  • 5 tablespoons salted butter melted
  • 3 ounces baking chocolate melted
  • 1 cup sugar
  • 2 large eggs
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 1/2 teaspoons vanilla extract
  • 3/4 cup all-purpose flour

Peanut Butter Crunch Topping

  • 1 cup creamy peanut butter
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 tablespoon butter melted
  • 1 cup rice krispie cereal*


  • Preheat your oven to 350 degrees and spray a 9x9 glass pan with nonstick cooking spray or line with parchment paper.
  • In a large mixing bowl, use a hand mixer to mix together melted butter, melted chocolate, and sugar. Add in the eggs, and vanilla and mix until combined.
  • Add in salt, baking powder, and flour and mix until just combined.
  • Pour the brownie batter into the prepared pan and bake for 20 to 25 minutes. Remove from oven and spread peanut butter on top. Let cool 1 hour.
  • In a microwave-safe mixing bowl, melt chocolate chips with butter in 15 second increments in the microwave, stirring in between, until chocolate is melted and smooth. Stir in rice krispie cereal.
  • Spread chocolate mixture on top of peanut butter layer. Transfer pan to the fridge and allow to cool completely until set, about 30 minutes.



*Increase Rice Krispie cereal to 1 1/2 cups total if you like an extra crispy topping.
*After spreading the peanut butter, you can speed up the cooling process by placing your pan directly in the freezer for a few minutes while you make the Rice Krispy topping.
