What are S’mores Brownies

S’mores brownies have all the key ingredients you’d find in the classic campfire treat. There’s the graham crackers, the chocolate, and of course, the toasted marshmallows. 

Here is a breakdown of these brownies:

  1. Graham crackers
  2. Fudge brownies
  3. Chocolate
  4. Toasted marshmallows

This dessert starts with a crispy graham cracker base which gets topped with a thick layer of rich, fudgy brownies. While the brownies are still hot, we melt some chocolate squares over top of them and then top the whole thing off with marshmallows. The marshmallows get a quick flash under the broiler or with a kitchen torch to give them a beautiful char. 

S’mores Brownies Ingredients

Marshmallows, eggs, sugar, butter, cocoa powder, salt, flout, chocolate, vanilla, graham crackers on a gray surface.
  • Graham crackers: Use your favorite brand of graham crackers. They can be original or cinnamon flavored. Or, if you are a real choc-aholic, use chocolate graham crackers!
  • Chocolate: For this recipe, I like to use bittersweet or dark chocolate to balance out the sweetness of the marshmallows. If you prefer the classic, use milk chocolate.
  • Marshmallows: You can use any size marshmallows you like – mini, regular, or jumbo.

Step by Step Instructions

  1. Base: Arrange graham crackers on the bottom of the lined pan.
  2. Brownie layer: Prepare the brownie batter and pour the batter over the graham crackers. Bake for 30 minutes.
  3. Chocolate layer: After 30 minutes, remove the pan from the oven and top with chopped chocolate. Allow the chocolate to sit for 3-5 minutes and then use a small offset spatula to spread the chocolate over the top of the brownies.
  4. Marshmallows: Arrange the marshmallows on top in rows and then return the pan to the oven for 5 minutes. After 5 minutes, remove the pan from the oven and use a kitchen torch to toast the tops of the marshmallows, or position the pan to the top rack of your oven and broil for 15-30 seconds. 
  5. Allow the brownies to cool for 20-30 minutes before cutting into squares. Enjoy!
