I am a true marshmallow lover. Are you? I love all things with marshmallows. And at the very top of my list is s’mores. Give me ALL the s’mores, please!

But let’s not stop at traditional s’mores. I love mashups. Like these brownies. There’s nothing better than a brownie, unless it’s covered in toasted marshmallow and has a graham cracker crust!! These brownies are INCREDIBLE! And they can be made with all store bought ingredients.

The Ingredients in Gluten Free S’mores Brownies

These brownies aren’t difficult at all. Even though there are 3 layers, store bought alternatives can be taken for each layer.

For the Graham Cracker Crust:

  • Gluten free graham crackers–there are several brands on the market currently that are great for making crumbs. I used Schar brand.
  • Granulated sugar
  • Melted butter

For the Brownies:

You could take the easy way out and use a gluten free boxed brownie mix, OR you could make homemade brownies in one bowl using these ingredients:

  • Melted butter
  • Brown sugar
  • Granulated sugar
  • Canola oil
  • Eggs
  • Vanilla extract
  • Gluten free flour blend–use Kim’s gluten free flour blend or a store bought blend containing xanthan gum
  • Cocoa powder–if you have a Lidl near you, their cocoa powder is dark and rich (and cheap, too!). It’s my favorite cocoa.
  • Salt
  • Chopped milk chocolate or milk chocolate chips–the traditional chocolate used in s’mores is milk chocolate. So instead of putting semi-sweet chips throughout the brownies, sprinkle milk chocolate (chips or chopped) on top of the graham cracker crust. They give another layer of flavor in the brownies.

For the Marshmallow:

Store bought mini marshmallows work great and are perfect if you want to make these brownies as easy as possible. Sprinkle them on top of the brownies. Then pop them back in the oven under the broiler to get nice and toasted!
