Summer equals s’mores and s’mores equals summer. At least for me! There is just nothing better than a bonfire on a summer night complete with a delicious s’mores in hand. I was inspired by the classic summertime treat, to create these S’mores Brownies. They are everything a brownie should be and more! I’m talking fudgy, gooey, rich, messy, decadent, and absolutely loaded with chocolate. I mean is there anything more you could want?

These S’more Brownies have a buttery graham cracker crust, a gooey brownie middle, and a toasted marshmallow top. They are pretty much the ultimate brownie and trust me they will leave everyone wanting s’more! I know … corny joke, but it’s the truth and I had to do it.

  4. Transfer the graham cracker mixture to a parchment paper lined 8×8 baking dish and flatten.

  6. While the graham cracker crust is in the oven, begin working on the brownie batter.  Start by melting the chocolate chips and butter.
  7. Add the melted butter and chocolate to a large mixing bowl and combine until smooth.  Add in the eggs, sugar, and vanilla extract.  Combine again.
  8. Next add the cocoa powder, flour, baking powder, and salt and mix until smooth.  
  9. Remove the graham cracker crust from the oven and pour the brownie batter on top.  Spread evenly.
  10. Bake for 30 minutes.
  11. Remove the brownies from the oven and add the mini marshmallows on top.
  12. Place back in the oven and bake for another 13-15 minutes.  Make sure to keep an eye on the marshmallows to prevent them from burning.
  13. Remove from the oven and let cool completely.

Tips & tricks for the perfect S’mores Brownies…

These brownies were a little tricky to nail down, but after three attempts I have all the secrets for the perfect brownies. They’ll come out fudgy and delicious each and every time!

  • The perfect graham cracker crust! I have a few tips for you to make the perfect graham cracker crust for your s’mores brownies. First, for the perfect crushed graham crackers add them to a bag and whack with a spoon. It’s honestly fun and an easy way to crush your crackers until fine! My second tip for the perfect crust is to add extra melted butter if needed. A good way to check if your crust is good to go, is if the crust mixture holds together when you squeeze it in your hand!
  • Don’t burn the marshmallows! Trust me, you want to keep an eye on your marshmallows. My first attempt at these brownies resulted in burnt marshmallows, which was very sad. Bake these brownies as the instructions describe for perfectly toasted & golden marshmallows!
  • Cool completely! This is very very important. These triple layered brownies have a lot going on and could fall apart if you cut into them before they have cooled completely! They will still be a little messy no matter what, but cooling these brownies helps to set them and really keep their form.
  • Use parchment paper! Lining the baking dish with parchment paper makes for such easy removal of these brownies. You just grab the paper and lift to remove the brownies from the pan with minimal mess and effort! Easy peasy lemon squeezy!

How to store S’mores Brownies…

You can store these brownies on the counter in an airtight container for about 5 days! If you want to keep these fudgy brownies fresh for longer, I recommend storing in the refrigerator in an airtight container. These will keep for 1-2 weeks in the fridge!
