I love these brownies because you can make them in advance, and they will stay delicious in the fridge for up to 3 days. Just let the brownies come to room temperature before serving.

Ingredients

For the Brownies:

  • 1 bag (12-ounce) semi-sweet chocolate chips
  • 1 cup butter (2 sticks)
  • 1 1/2 cups granulated sugar
  • 1 teaspoon vanilla
  • 1/2 teaspoon salt
  • 4 large eggs
  • 1 1/3 cups gluten-free 1:1 baking flour

For the Peanut Butter Crunch:

  • 1 jar 7-ounce jar marshmallow crème
  • 1 cup peanut butter
  • 1 cup semi-sweet chocolate chips
  • 3 cups Cocoa PEBBLES™ cereal

Instructions 

  • Preheat the oven to 350F. Line a 9x13 baking pan with tin foil. Grease with cooking
    spray and set aside.

Make the Brownies:

  • Place the chocolate chips and butter in a medium-sized microwave safe bowl.
    Microwave on 50% power for 2-3 minutes, stopping every 30 seconds to stir until
    completely smooth and melted. You can also melt the butter and chocolate together
    over low heat on the stove.
  • Add the sugar, vanilla and salt to the chocolate mixture. Whisk to combine. Add the
    eggs one at a time, whisking until fully incorporated after each egg. Stir in the gluten-
    free flour until incorporated.
  • Pour the batter into the prepared baking pan. Smooth into an even layer. Bake for 30-35
    minutes until set and a toothpick inserted into the center of the brownies comes out
    clean. Let the brownies cool completely.

Make the Peanut Butter Crunch:

  • Spread the marshmallow creme over evenly over the cooled brownies.
    In a saucepan over medium-low heat add the peanut butter and chocolate chips. Stir
    until melted. Remove from the heat and stir in the cocoa Pebbles cereal.
  • Smooth the crunch mixture over top of the brownies. Refrigerate for 30 minutes to set. Cut into bars and serve. Brownies can be stored in the fridge for up to 3 days. Enjoy!

    So amazing, Erin! We had dinner with an individual who has celiacs disease and I brought these! They were amazing!! The crunch on top gave the perfect balance to the fudgy brownie! It all worked so well together!

  2. 5 stars
    I only made the brownie part, and not the topping but the brownie is delicious and holds together really well. The texture is more like fudge or a flourless torte. So if you prefer a cake-y brownie, as I do, you may be slightly disappointed with the texture. Based on the flour content, I anticipated this going in. I added 1/2 cup unsweetened cocoa to this recipe because I like a really chocolate-y brownie.

  3. Hi Erin,

    These look amazing! Would it be possible to substitute the eggs for something else, like flax eggs?

    Thanks!

    K these are soooo rich and delicious, yum! The crunch gives it the perfect texture and I love how gorgeous the layers look.

  5. 5 stars
    These are seriously so dreamy! There is nothing like a chocolatey, crunchy, and delicious treat! You won’t believe how easy they are to make.

    1. Yes that should work! I would probably do half vegan butter half coconut oil though. That would work well with texture/flavor!
