I LOVE s’mores and these S’mores Brownies are a simple way to get all of that chocolate-y, marshmallow-y, graham cracker goodness without having to sharpen stick and build a fire. S’mores brownies have all of the amazing s’mores flavors baked into delicious brownies. Perfectly toasted marshmallows without the need for an open flame :). In my opinion s’mores are the perfect dessert all year long but these S’mores Brownies are especially awesome for summer and fall parties, or a simple treat for family night.

Step-by-step instructions for making S'mores brownies

How to make S’mores Brownies:

  2. Place a layer of graham crackers on the bottom of a greased 9 x 13 inch pan (or whatever size pan your brownie mix calls for).
  3. Pour 1/2 of the brownie mix over the graham crackers.
  4. Add a second layer of graham crackers.
  5. Pour the remaining brownie mix over the graham crackers.
  6. Bake brownies according to package instructions or until a toothpick inserted in the center comes out clean.
  7. Top brownies with a layer of marshmallows that have been cut in half and broil for 2-3 minutes until marshmallows are perfectly toasted.

When the S’mores Brownies come out of the oven those marshmallows on top are all meted and perfectly toasted. You won’t be able to resist cutting into them right away! This is such an easy way to make s’mores for a crowd. Smores’ and brownies are irresistable, put them together and you have the ultimate dessert!

Tips for making S’mores Brownies:

  • We took standard size marshmallows and cut them in half to make our top layer but you can use any size marshmallows you like.
  • I love the graham cracker part of s’mores so I made two layers of graham crackers so you really get the flavor. Melinda likes a little less so she eliminates that second layer of graham cracker. It’s totally up to you!
  • If you want to change it up a little you can also use chocolate graham crackers to make your S’mores Brownies!
