s'mores brownies

I just felt like my our Thursday could use some chocolate.

And marshmallows.

And the butteriest (<–definitely a word) graham cracker crumble.

And more chocolate.

You understand.


It has been a sort of high stress week at work, where I am trying to tie up a lot of loose ends so I can get my paper written and submitted, and I am slightly ashamed to admit that this has turned me into a raving bitch lunatic.

Evvvveerryyyttthhhiiinnngg irritates me.



Namely: people who leave messes in common areas with no intention of cleaning them up,

people who use up the last of a common reagent and don’t tell anyone, and ummm.

People. Any and all.


It’s a problem, especially when you’re in the kind of work environment like I am, where everyone is in close quarters at all times.


And a chill pill.

And more chocolate.

(And tequila shots.)


Since I don’t see the majority of those things happening in the near future, I went with the one thing that I can control.


Brownies for me! Brownies for you! Brownies for my coworkers so they can remember that I am actually a nice person underneath this bitchy grouchy exterior! And brownies for my Leftovers Club partner, Johanna from Notes from A Messy Kitchen, because this recipe makes a LOT of very fudgy very RICH very DECADENT brownies and no one should be tasked with devouring all of them! It will be hard to resist because they are hella good…but trust me. This is a one and done situation. But it will be so satisfying.

Stress Free (Brownie Filled) Thursday? We got this.

S'mores Brownies
These s'mores brownies are THE ULTIMATE with a fudgy brownie base topped with gooey burnt marshmallows, a dreamy milk chocolate ganache, and a crunchy graham cracker crumble.
Yield: 16 brownies
For the graham cracker topping
  • 1½ cups graham cracker crumbs
  • ¼ cup sugar
  • 5 tbsp butter, melted
For the brownies
  • ⅔ cup butter
  • 5 oz unsweetened chocolate, coarsely chopped
  • 1¾ cups sugar
  • 2 tsp vanilla extract
  • 3 large eggs
  • 1 cup all purpose flour
  • 5 cups mini marshmallows
For the ganache
  • 6 oz milk chocolate, chopped
  • ⅔ cup heavy cream
  1. For the graham cracker topping, heat oven to 350F. In a medium bowl, whisk together the graham cracker crumbs and sugar. Stir in the butter until all the crumbs are moist. Line a baking sheet with parchment paper and press the crumb mixture into a 10-inch circle. Bake for 10 minutes. Let cool.
  2. For the brownies, heat the oven to 350F. Line a 9x13-inch pan with parchment paper. Set aside.
  3. In a microwave-safe bowl, melt the butter and chocolate together in 30 second intervals, stirring after each, util melted. Allow to cool to lukewarm.
  4. In the bowl of a stand mixer fitted with the paddle attachment, beat together the sugar, vanilla, and eggs on high speed for five minutes. Beat in the chocolate on low speed until combined, scraping down the bowl as necessary. Add in the flour and mix until just combined.
  5. Pour the batter into the prepared pan and spread in an even layer. Bake for 28 minutes. Remove the pan from the oven and scatter the marshmallows over the top. Bake for 12-14 more minutes or until the marshmallows are golden. Remove from the oven and let cool.
  6. To make the ganache, put the chocolate in a small heatproof bowl. Heat the heavy cream until it just starts to boil. Pour over the chocolate and let sit for a minute. Whisk the mixture until it comes together and is smooth. Let cool until lukewarm.
  7. Pour most of the ganache over the marshmallows. Sprinkle with the graham cracker crumble and then drizzle with the remaining ganache. Let cool in the fridge for a few hours to set up. Slice into squares before serving.

  8. Sues says:

    If I had these in front of me, I wouldn’t care about any messes or basically anything else at all. Tequila would still be nice though 🙂

  9. I don’t think there could be a more perfect brownie! Each layer looks amazing. That drizzle!

  10. I am freaking out! These brownies, man, I can’t handle it’s awesomeness! I’m asking for a transfer (and changing my career) – I’m arranging to be one of your co-workers! Brownies here I come!!

  11. Jen says:

    I’m loving the sound of a s’mores brownie. I mean just look at them. They look delicious!

  12. Trisha says:

    Joanne, I am DYING over these. I want to be your co-worker. I totally feel you on the lunatic craze with all the paper stress. When I am in the middle of exams, I get seriously annoyed by the smallest things. Chocolate makes everything better though. 🙂

  13. Marci says:

    These look so decadent and perfect. Tempted to cancel all of our activities today to make these.

  14. This is seriously rich and divine! I love the gorgeous layers.

  15. Heather says:

    It’s recipes like this that make going sugar-free impossible for me. I contemplate it and start planning and then… I see something like this and don’t even want to think about a world without rich gooey brownies.

  16. Damn girl these are goooooooood! GANACHE- that is why! I want to eat these NOW!

  17. Emma says:

    This recipe is really NOT appreciated because I’m moving in three weeks and trying to use up what’s in my pantry and now I’m going to have to go out and buy ingredients to make these ASAP.


  18. Johanna says:

    Hmm, about that one and done thing… THESE WERE AMAZING! And you removed all the calories for me… right? 😉

  19. Susan says:

    Co-workers are the worst but I always found you can buy them back with brownies and these look like they’d do the trick.

  20. Julia says:

    Ohhhhh girl, I’m sorry to hear you’re having a rough week! And yes, people in general tend to piss me off, so I can understand the need for space + a clean environment that no one else is muddying up, ha! Hang in there and in the meantime: s’mores brownies + tequila 😀

  21. I heart you for making time to see me when your week is so crazy!! And gah these brownies…. holy yes!

  22. Ala says:

    Pahaha maybe if you threw a tray of these brownies into the common areas and then set up a booby-trap for anyone who takes some without cleaning up, it would solve the problem? Regardless, hope the rest of your week gets better – we’re almost there! LOVE this chocolate boost!

  23. These look like a cure for just about any problem (irritation, journal papers, work, people, life…) as well as a way to make even the good days better!

  24. Chocolate sure cures all problems (especially these brownies)! So sorry that things at work are super stressful lately! I’ll be glad to be your tequila shots buddy if you need one! 😉

  25. Faye says:

    Amazing as usual! You never cease to impress!!

  26. If I’m being honest, s’mores are my favorite part of camping – so, obviously, you have my full attention with these gorgeous brownies!!

  27. i could totally go for one of these brownies today. yummm!

  28. I’m feeling the lab stress! I ran around for 30 minutes the other day looking for a solvent that “should” have come in weeks ago — only to later find out that the person who needed it never actually ordered it. I usually bring in a homemade treat or buy bagels once every 2 weeks or so to remind everyone that I’m a decent human being and not always stressful ‘n sassy. these would be a perfect summery treat.

  29. Having kids makes you more accepting of messy spaces. (<< total lie.) Can every day be Thursday? Because I need these brownies.

  30. Kate says:

    Smores are the new black. For real, I think I’ve seen smores flavored just about everything this week!

  31. I wish I had a couple in front of me right now! Definitely would help make this stressful week a bit better!

  32. Kelly says:

    Wow! Look at those gorgeous layers! These brownies would sure make my week better. Sorry about the stressful week, hopefully these helped somewhat 🙂

  33. Elizabeth@ Food Ramblings says:

    Now I want to go camping 🙂 These look AMAZING!

  34. Definitely adding these to my bake list – they look sooooooooooooo delicious:-)

  36. Oh dear god I thought for a moment that I forgot to mail out my goodies this month before remembering that I didn’t sign up this month. Phew. While I am not writing a paper at the moment (but of course I can relate) I have had quite the week and am ready to sit on the couch and not talk to anyone. But with it being my birthday week that will not happen just yet as there are festivities to attend this weekend. Not that I am complaining really :-). Except that I do not have one of these bars in front of me.

  37. Wow these look amazing! I could always use some brownies especially is they are stuffed with marshmallows! Yum!

  47. Oh, I hear you! Some days or weeks are just like that. I’m sure you’ll feel better, especially if you make another batch of these brownies. Such a great idea!

  48. Foodiewife says:

    I can’t even… I’ve been obsessing with creating a S’Mores brownie recipe. Mine’s a bit different, in fantasized execution. But these… O.M.G. These are so damn tempting, you minx. Mine!

  49. Shaina says:

    Oh my god these look insane. Got any left over leftovers!?!?! 😉

  50. Chocolate is the best cure all 🙂

  51. These look seriously delicious! I love that you have the crumb topping made with graham crackers! I just need to get graham crackers and then I have all the ingredients! This is at the top of my list of new desserts to try!

  52. I know that these brownies would make me happy. Yum!

  53. Lynn says:

    I’m SO making these!

  54. elly says:

    I loooove that these have a graham cracker crumble instead of a crust on the bottom. Can’t wait to make them!
