For a girl who drinks sparingly at best…

…these moon pies pack a seriously alcoholic punch.

Bailey’s, Guinness, and whiskey.  All wrapped up in one marshmallow-filled, chocolate-covered TRIPLE.DECKER. cookie sandwich.

Suffice it to say, these are not for the faint of heart.

Or the diabetic.

Or the recovering AA member.

Or any child under 21 years of age.  (18, if you’re my mother who still believes that that is the legal drinking age. I’m neglecting to tell her otherwise.  For my sister’s sake.)

But a group full of scientists at 10AM on a lazy Wednesday morning who are supposed to be discussing the metabolic state of cancer cell microenvironments and showing graph upon graph full of negative and completely meaningless results (ummm that last part was just me)?

Well, let’s just say that completely not statistically significant data looks much more promising after you’ve gotten your Irish car bomb moon pie buzz on.  For realz.

I’m fairly certain this holds true for just about any work meeting environment…so go forth and bake…and then force what you’ve baked upon your unsuspecting coworkers.  And if you happen to neglect to mention just how much alcohol was in these babies until everyone is back at their lab benches and too tipsy to hold a pipette…

…I’ll tell you to join the club.  Shrug.  Oops!


Okay, but the real deal with these is that if you are anyone other than a constantly-slightly-dehydrated 25 year old female…these will like not have any effect on you other than the placebo type.  Which is to say that all this sugar and chocolatey deliciousness will rush to your head and make you very.very.happy.

Which isn’t such a bad deal either.


They’re also perfect for those of us who are absolutely prohibited from drinking on St. Patrick’s day this year…due to the whole running-13.1-miles-at-7:30-in-the-morning-the-next-day half marathon thing.

(Not that we were really going to anyway…but at least now we have a less lame excuse than “I don’t wanna!”)


To be totally honest with you, these are seriously time consuming but in a totally worth your while kind of way.  The chocolate guinness cookies are the easiest roll-out cookies I’ve ever worked with.  I rolled them out on parchment paper and didn’t have to flour either the table or my rolling pin.  That kind of easy.

The marshmallow creme frosting requires boiling sugar and a candy thermometer…but don’t be scared.  Once you get over the fear of pouring 230 degree sugar all over your limbs, it’s really smooth sailing.  Wear a rubber body suit if you’re really concerned…maybe the one from Britney’s “Oops! I Did It Again” video.  It’s a classic.

And once you get through all that…the chocolate glaze is a piece of cake.  Err moon pie.  Same difference.

Irish Car Bomb Moon Pies
Makes about 2 dozen, cookies adapted from here, marshmallow creme and chocolate glaze adapted from here


For the Chocolate Guinness Cookies:

    • 24 oz guinness
    • 1/2 cup brown sugar
    • 6 cups AP flour
    • 1 1/3 cup unsweetened cocoa powder
    • 1 tsp salt
    • 1 tsp baking powder
    • 2 cups unsalted butter, softened
    • 3 cups sugar
    • 2 large eggs


For the Bailey’s Marshmallow Creme:

    • 2 egg whites
    • pinch of cream of tartar
    • pinch of salt
    • 2/3 cup light corn syrup
    • 2 tsp vanilla extract
    • 1/4 cup Bailey’s Irish Creme
    • 2 1/2 cups confectioner’s sugar

For the Whiskey Chocolate Glaze:

  • 12 oz semisweet chocolate
  • 1/4 cup vegetable oil
  • 2 tbsp whiskey



For the cookies


    1. Add the beer and brown sugar to a medium saucepan.  Reduce the liquid over medium high heat until it thickens to a syrup and measures approximately 1/3 cup.  This will take about 30-45 minutes.  Allow to cool slightly before using.
    2. Preheat oven to 350.  Sift together flour and cocoa powder into a large bowl. Whisk in salt and baking powder until evenly incorporated.
    3. Cream butter and sugar in the bowl of an electric stand mixer fitted with a paddle attachment until light and fluffy, about 3 minutes. Add eggs one at a time, until well incorporated, scraping the sides after each addition.
    4. Add the Guinness syrup and beat until incorporated. Turn dough onto a lightly floured work surface. Divide into four pieces with a knife or bench scraper. Shape each mound of dough into a ball, flatten into a disk, wrap in plastic wrap, and chill for at least one hour.
    5. Roll out one disk of cookie dough onto a sheet of parchment paper until 1/4 inch thick. Cut into circles using a 2-inch cookie cutter. Re-roll out scraps of dough and cut into cookies until all is used.  Repeat the rolling/cutting process with the remaining disks of dough. Bake cookies on a parchment-lined baking sheet for 8 to 11 minutes, until the edges are firm and the centers are slightly soft and puffed.
    6. Transfer to a wire rack to cool.

For the marshmallow creme:

  • Using a mixer with the whisk attachment, beat the the egg whites with the cream of tartar and the salt until firm peaks form, gradually increasing from medium-low speed to medium-high speed as the egg whites gain volume. Meanwhile, in a small saucepan, boil the corn syrup over high heat without stirring until it registers 230 to 235 degrees F on a candy thermometer. Slowly drizzle the hot corn syrup into the egg whites and beat at high speed until glossy, about 2 minutes. Reduce the speed to medium-low, beat in the vanilla extract, Bailey’s, and the powdered sugar.
  • Using a small cookie scoop, mound the marshmallow filling into the center of 1/3 of the cookies.  Top with another cookie and press lightly to spread the marshmallow to the edges.  Add another mound on top of this cookie and top with a third cookie, pressing down to fill the edges again.  Repeat with remaining cookies.


For the glaze:

  • Using a double boiler, heat the chocolate and the vegetable oil until melted and completely smooth.  Stir in the whiskey.  Place the assembled cookies on a wire rack set over a sheet of wax paper.  Spoon the melted chocolate over each cookie so that it drips down the sides and covers most of the cookie (nudge it if you have to!).  Allow to set up at room temperature for at least two hours before serving.

Speaking of eggs, can we talk about eating them raw for a second?  And no, I’m not talking Gaston from Beauty and the Beast style consumption, but rather…the ingestion of tempered eggs.  Eggs that you think you’ve scrubbed of all their salmonella by bringing them into contact with warm liquids.  Eggs prepared such as those in ice cream or mousse or swiss meringue buttercream or…this marshmallow creme frosting.  Well…we were wrong about them.  As it turns out, they’re not as safe to eat as we’ve always believed.  And while it will probably be okay for those of us with totally efficient immune systems to ingest them, the same is not true for the immunodeficient – those on chemo, small children, and pregnant women, to name a few.

Thankfully, as I learned at an amazing event hosted by Rose Levy Beranbaum a few weeks ago…there is now a solution – Safe Eggs.  These eggs are pasteurized, making them totally safe to eat raw.  Not only that, but they behave exactly the same as non-pasteurized eggs in baking and cooking (and even make for more stable meringues, according to Rose!).  I used them in this marshmallow creme frosting with great results.  And it definitely helped me sleep at night knowing that there was not a single chance that anyone was going to get a bacterial infection from ingesting them.  Score.  I’ll definitely be using them in the future for all my raw egg needs!

Thanks so much to Safe Eggs for inviting me to attend the event and to Rose for being so amazing! She was full of the most insane baking tips and was one of the nicest people I’ve ever met, staying afterwards to talk shop with my friend Lauren and me long after the event had ended.  And did I mention that she baked us a cake?  (It was good.  Seriously so.)

  1. First of all, these look just as amazing as I thought they would be! Second, love your shots from the egg event. Now I want more of that cake… er… really the frosting!

  2. Time consuming but seemingly so worth it! These moon pies look to-die-for!! Have a fabulous race on Sunday!! Looking forward to hearing about it 🙂

  3. I dare you to eat three of these and race!

  4. Epicurea says:

    i’m still speechless in face of all the possibilities of these cookies – bailey’s, guinness AND whiskey!! plus thx for the safe egg info!

  5. Louisa says:

    I made Irish Car Bomb cupcakes last year for St Patricks day. This year I want t make these. Moon pies are a “thing” in my family. Moon Pie was my sister’s nickname when she was little.

  6. OohLookBel says:

    I’m too scared of boiling sugar to attempt these amazing pies, so I’ll just gaze at your pics for now. PS: Pasteurised eggs, what will they think of next?

  7. Ahhhh the chocolate glaze makes this really look fabulous. Awesome idea!

  8. Jeanette says:

    What a treat for St. Patrick’s Day, and how cool to get to meet Rose Levy Beranbaum and to taste one of her cakes!

  9. Good luck on your marathon, Joanne. 🙂

  10. Johanna GGG says:

    yum – wish someone would bring these sort of treats to my workplace – and love the marshmallow creme with no gelatine – plus the info about those eggs – I have always wondered if eggs that are in contact with hot liquid but not cooked are still raw – though it seems we have good immune systems in our family or good luck because a favourite slice has these sort of uncooked eggs in hot liquid! BTW I think maybe you need one of these moon pies after your run

  11. Awesome, what a cool experience. And double awesome on these killer moon pies! A. Maze. Ing. and sinful. want one!

  12. kelsey says:

    Dear God woman you are going to kill me. I need this.

  13. Kim says:

    I’m excited to read about the safe eggs because I do worry about making things with raw eggs. And, how awesome that you got to meet Rose! Even better that she was so nice.

    Those car bomb moon pies look killer right now. I’m loving how original and unique they are.

  14. The car bomb looks so delish. I have never had a moon pie! I think I should change that!!

  15. Adrienne says:

    These look absolutely delicious. I’m sure my family would flip if I made these. Maybe I should start running half marathons on March 18th so I have a good excuse not to drink too!

  16. Hehe! I made Irish Car Bomb CUPCAKES last night! As I was leaving the liquor store the guy behind the counter snickered and said “enjoy your car bombs…” and I was like “I’M MAKING CUPCAKES!”

    You get points for being WAY more original than me by making moonpies 🙂 I was too scared to bring mine into work since they smell so boozy, even if I doubt they’ll give anyone a buzz.

  17. Danielle says:

    oh my goodness these look crazy good!

  18. Ooooohhhh these sound perfect for the weekend! I might just make the Guinness cookies and dunk them in straight up Baileys…

  19. Ranjani says:

    These look insane! I do love booze in baked goods so I’m going to have to give these a try. btw, I’m not drinking on Saturday for the same reason as you (yay, my first half!)

  20. Amy says:

    Maybe this is what all the politicians in Washington are high on, making them delusional!

  21. Good luck on your half marathon, Joanne!!! I’m sure you’ll do great 🙂

    These look positively amazing but I think I’m too lazy to attempt them, hehe.

  22. Oh my, these look insanely good!

  23. They look absolutely fantastic! Could I have more chocolate on the side for dipping?
    Cool you got to hang out with Rose Levy Beranbaum.

  24. Jenna says:

    Pasteurized eggs! Fascinating. That would allow me to eat all the cookie batter I want without my husband crying “salmonella” in the background . . . score!

  25. Faith says:

    Oh wow, I thought they looked amazing before the chocolate glaze! And then I saw that second photo…if I had been standing, I know I would have been weak in the knees, lol!

  26. Margarita says:

    A booze-filled dessert! Nothing can be more crazy awesome than this… Wish I lived next door to you so I can just knock on your door and ask for one or two of these. By the way, what kind of delicious cake did the awesome lady make for you? It looks delish!

  27. Gloria says:

    look amazing Joanne!!

  28. Pam says:

    My husband would dig all the alcohol and chocolate in those babies. They look decadent and delicious. Happy St. Patrick’s Day! Good luck tomorrow!!!

  29. Sippity Sup says:

    Great looking whoppie Pies, with a very strange name. PS I would trust Rose on any baking matter at all. GREG

  30. Nicole, RD says:

    Too funny – my mom thinks the drinking age is 19…because that’s when you could get into bars in college. Silly moms.

    I love everything about these moon pies! Happy weekend, love!

    P.S. If those goes through…my comment got eaten 3x 🙁

  31. Shannon says:

    what amazing pies those are… might just have to make them for my next lab meeting 😛

  32. Isn’t it funny when you have to give a disclaimer for food? Loved your kitchen photos.

  33. You’ve outdone your self with these, Joanne. And your photos are so creative, this is just a pinnable post from beginning to end! I discovered Safe Eggs last week and I’m so excited, I’m a complete wimp when it comes to food poisoning 😉

  34. RJ says:

    oh lovely! I just bought up some guinness to make some boozy cupcakes, can’t wait to try these cookies with the leftovers 🙂

  35. Amazing looking dessert. I bet the presentation by the scientists was really interesting, for the first time ever:) Wish I had a few of these when I was forced to read Shakespeare.
    I was excited until I saw the ingredients – 1/4 cup Bailey’s and 2 tbsp whiskey. This is suitable for babies:) If you eat the whole batch you may get tipsy, maybe, only just.
    I read that pasteurised eggs were quite common these days, not sure if some or most of them are (over here anyway).

  36. Reeni says:

    I would totally overdose on these and get tipsy and then pass out. All before noon. But it would be worth every delectable bite! Good luck on Sunday! I’ll be silently cheering you on.

  37. These look AWESOME!! you recipes are fantastic -I get hungry every time I get you r emails. Also some friends of mine from Garden City will be running in the half marathon this Sunday too. good luck!

  38. Mary says:

    I love the cookies. How can you not love something with that name:-). Good luck on Sunday. Blessings…Mary

  39. Chris says:

    I feel a buzz just from reading the list of glaze ingredients. These are wicked things, in a great way! Good luck on your run sunday.

  40. Lynn says:

    The title alone would make me want to try those. 🙂

  41. Christine says:

    As many have already said, the title alone made me look! These sound totally decadent!
    Happy St. Pat’s Day, hope you have a super run!!!

  42. Donna says:

    Who needs green beer tomorrow when you can have these babies instead? Luck ‘o the Irish to Ye!

  43. Julia says:

    Good thing I fall into none of the categories that would prevent me from eating my fair share of drunkard cookies. Oh wait, that’s not the official name of them?!?!

  44. Elizabeth says:

    Daaang. Also Rose’s cake looks excellent too.

  45. Hannah says:

    I’m a total lightweight (1 glass of champagne has seen me tripping over the toilet, BOTH of two times I’ve ever imbibed) so I have no doubt these would knock me out. It’d be so worth it though.

  46. annie says:

    Your moon pies look and sound delicious! Very lovely photos! I’ve never heard of safe eggs, but happy to learn about them.

  47. Candace says: There are no words for how wonderful these desserts look. My diet is in danger tonight in a huuuuuuuuuuuge way.

  48. Gracie says:

    OMG…I want one or 20 of those!!! Yum.

  49. Now that is a St. Patrick’s Day recipe that I’d love! They look incredible! When my daughter was pregnant I would only buy pasteurized eggs when I made anything egg-related for her. I also made sure cheeses were pasteurized too. Great advice! Now, I’m ready for a moon pie!

  50. Lora says:

    These are AMAZING! Wow oh wow.

  51. Carolyn Jung says:

    Bring ’em! LOL I am ready for those make-my-knees-quiver moon pies. 😉

  52. Oh these look so delicious. After I read your posts I am ready to go back in the kitchen and start cooking again!!

  53. sophia says:

    Um, hell yes. I know one friend who would totally flip over these. They are BOMB!

  54. As you saw, I discovered the Guinness tastes pretty amazing IN a recipe. Now that I tried it for a savory glaze, I’ve been debating trying it with chocolate. You hit this one right out of the ballpark. Chocolate and marshmallow. My weakness. All my life, I’ve never been nervous about eating egg whites. So far, so good. But, it’s nice to know that there are options. What a fun event for you to attend. So, um, what kind of cake is that? Looks great in itself.

  55. Dining Alone says:

    I have seen so many recipes that include guinness this week, but this one might be the best.

  56. Jamie says:

    That Bailey’s Marshmallow Creme sounds amazing!! I have always worried about the whole raw-egg issue also – I’m so glad you were able to give me that information so I can make this recipe now!

  57. I was all set to comment on the cookies, until I saw photos of Rose and freaked out. FREAKED! I can’t believe you met her and she made you a cake! I would have died. What an insane opportunity. I have her cake Bible and love her eggwhite chocolate buttercream (raw egg whites) but I’ve never had anyone get sick from it. Although, if I find Safe Eggs around here, I will use those next time! Anwyay, back to those beautiful cookies! I love that you incorporated all three ingredients of an Irish car bomb–wish I would have done that with my Guiness & Bailey’s creations b/c it would have made naming them a lot easier-lol–my titles are like a page long-haha. So what did you do with your extra booze? Do you HATE Guiness as much as I do? OMgosh, it’s so gross I just had to toss it despite having a distaste for waste. Let me know if you have any brilliant idea for the leftover Bailey’s!

  58. Julie says:

    Happy St. Pat’s Day! This looks delicious.

  59. Nina says:

    Wow….these are sinful. The pictures are drool worthy:)

  60. Oooooh my. These look AMAZING!!! I hope you’ll stop by and link these up at my St. Patrick’s Day blog hop! And thanks for the info re: safe eggs. Very interesting.

  61. That Girl says:

    This is definitely more cake than cookie

  62. Anonymous says:

    Although they look yummy, I find the name of these to be offensive.

    • Joanne says:

      Anonymous – I know the name isn’t exactly PC…I just named them after the drink since they feature the same three alcoholic ingredients (bailey’s, whiskey, and guinness). I’m sorry you find it offensive! that was never my intention.

  63. Barbara says:

    Thankfully, I CAN drink tonight. And will. But I sort of wish I had time to make these this afternoon. Saving this recipe, for sure.
    Now…as for Rose Levy Beranbaum: you lucky girl, you. I would KILL to have been there. Next to Maida Heatter, she is the queen of baking. And even Maida says she is the best. Now why didn’t she make the game-changer list??? So many talented women did not get on that list.
    (BTW: PC has gone mad in this country. And why anonymous?)

  64. OMG they looks devilishly delicious 🙂 Chocolate goodness I am way tooooo tempted.

    Yumm !!!


  65. Your pictures are out of this world. These look fabulous and I can’t tell you how badly, I want one or two or……

  66. Mary says:

    Ok, I had so many brilliantly witty things to say (oh, wait, before I forget AGAIN, GOOD LUCK tomorrow!) and then I saw Rose. Holding the cake in the AIR whilst frosting it. I’m so completely in awe. I’m such a frosting klutz in the first place… just imagining holding a layer aloft has me laughing. I would have loved to be in that class!

  67. Happy St. Pat Pat’s Day!! Looks really great!! I love the chocolates drizzle and love how messy the chocolate looks on it!

  68. Katerina says:

    You found the best way to celebrate St. Patrick’s Day Joanne! They are totally addictive and look super delicious!

  69. Maureen says:

    I can still remember the first time I had a moon pie. It was in Knoxville, Tennessee in 1971. Now that dates me, doesn’t it? 🙂

    These look SOoooo good!

  70. Bailey’s marshmallow cream. Wow. Want!

  71. Jenn Kendall says:

    oh wow these look awesome!! yum!

  72. Ben says:

    Drinking age? What’s that? Hehehe. I could totally get drunk on that cake. It looks just superb!

  73. These look like the perfect cure for non statistically significant data – you must have been extremely popular with your coworkers for these!!

  74. marla says:

    A MUCH better choice then green beer 😉 LOVE the moon pies!

  75. These. look. insane. And, by insane, I mean absolutely delicious!!

  76. Ahh Joanne these decadent treats look amazing and as usual, I truly enjoy your wit. I also love the way you-all pun intended-sandwich these delectable morsels in between healthful bowls of green beans in Thai Curry, eggs over legumes and swiss chard and a quick mention of a half marathon to offset the marshmallow!!! Everything in moderation, right?

  77. JasmyneTea says:

    Those safe eggs are really interesting! I always feel sorry for my pregnant friends when I make mousse or something and they can’t have any, lol. The moon pies look great!

  78. grace says:

    moon pies are fun, but these are spectacular! there’s nothing good about car bombs unless they’re irish. 🙂

  79. Camila Faria says:

    Beautiful Joanne! That’s why I love the irish!

  80. Let’s get drunk on cookies 😀 quite possibly THE best way to get drunk haha

  81. daphne says:

    oooo… chocolate and alcohol- perfect combo! The thing to bring to a scientist meeting for sure 😉
    And i didn’t know that about eggs! It’s 7:25am now and I learned something new for the start of the day!

  82. I can’t think of a better pairing. In terms of eating raw eggs, I understand the need to be careful, but I also think it’s important to get eggs that are raised locally and that come from chickens that are treated fairly.

  83. Catherine says:

    Dear Joanne, What a great Moon Pie!! Certainly kicked up a notch since I was a kid. I just don’t eat raw eggs. It is something that I just can’t bring myself to do.
    Have a wonderful evening. Blessings my dearest, Catherine xoxo

  84. sally says:

    Oh my! Alcohol and chocolate–what a great combo for moon pies!

  85. kyleen says:

    These moon pies look like just the thing to wake me up tomorrow morning–I need a kick of happy for the first day back to school after March Break. And I didn’t know that tempering the eggs like when making a buttercream didn’t count as cooking! I’ll definitely have to look out for Safe Eggs.

  86. Oh my word, I haven’t had a carbomb in FOREVER! Thank you for reminding me, I think these days I’ll take the moon pie over the drink thanks!

  87. These look WAY too dangerous for words. 😉

  88. Hotly Spiced says:

    Those cookies look amazing and I’m sure they’re filled with wonderful flavour. Your work meetings sound very intense – not wonder you have to resort to such decadence and alcohol soaked treats. And what a great name for a cookie! xx

  89. Okay first of all yeah for safe eggs! with a toddler and new baby I will definitely be investing in these eggs as I hate the idea of them getting sick off bad eggs. Secondly, did you say irish car bomb and moon pies in the same sentence? YUMMMM!

  90. Lucky you attending this class. I am not sure where we are up to on the Pasteurised eggs in Australia. The cookies look amazing and I always wanted to know how to make that mashmellow icing

  91. Beth says:

    It must have been a thrill to meet her. I love her pie cookbook, and hope that someday that’s what will get me over my fear of pastry.

  92. How exciting to meet her!! and hey pass me three of these bad boys..momma needs a break!!

  93. Holy moly…these look amazing!

  94. Love the sound of these cookies! I was wanting to make those car bomb cupcakes but have yet to do that. And now I want to make both the cupcakes and these cookies!

  95. Elizabeth says:

    That’s fascinating about the pasteurized eggs. And I thought it must be possible to pasteurize eggs at home. I know one can’t believe everything on the internet but this looks like a viable solution for someone who would like to have pasteurized eggs but not pay the hefty markup:

  96. Elizabeth says:

    They look delicious – but as you probably know I’m always up for anything that calls for whiskey. 🙂

  97. Holy COW. These are amazing! And your comment about your mom and sis made me laugh! I wish my mom had thought that…

  98. Blue Sky says:

    Waitaminnit! 24 oz. reduced to 3 oz.? Really? reduce by 8X? Sounds crazy, and I want to make sure I’ve got that right before I sacrifice 24 oz. of my milk stout to the cause. Do I really boil 24 oz. of beer (and sugar) down to a mere, smear 3 oz.? Please advise!

    • joanne says:

      Yes, it is definitely 24 oz reduced down to ~1/3 cup. You want the flavor to be very concentrated, so you’re basically just boiling off water. If you add more liquid than this, the cookies will be too cake-like and not thin and crispy like you need for these.
