Peanut Butter Chocolate Brownies

Peanut Butter Brownies > Regular Brownies – FACT!

Everyone needs a good brownie recipe in their back pocket. I’ve been making the same fudge brownies for years and LOVE them. I decided to give my recipe a bit of a makeover to the tune of a peanut butter swirl. To up the ante, I folded in chopped peanut butter cups. The result was rich, decadent, and uber delicious. I love being able to tweak my existing recipes just a bit to create something entirely different but just as good! Do you ever experiment with recipes that you make over and over again?

Peanut Butter Chocolate Brownies

  • Author: kelsey nixon
  • Yield: 24 servings 1x


  • 1 cup unsalted butter, melted
  • 3 cups granulated sugar
  • 1 tablespoon vanilla extract
  • 4 large eggs
  • 1 1/2 cups all-purpose flour
  • 1 cup unsweetened cocoa powder
  • 1 teaspoon salt
  • 1 cup peanut butter cups, chopped plus more for topping, if desired

Peanut Butter Swirl

  • 1 cup smooth peanut butter
  • ½ cup powdered sugar
  • 4 tablespoons unsalted butter, softened


Preheat oven to 350 degrees F . Lightly grease a 9 x 13 baking dish or line with parchment paper or foil leaving an overhang so that you can easily lift brownies out of pan after baking.

Combine the melted butter, sugar, and vanilla in a large bowl. Beat in the eggs, one at a time, mixing well after each, until thoroughly blended.

Whisk together the flour, cocoa powder, and salt. Gradually stir the dry mixture into the wet mixture until blended. Batter will be thick. Stir in the chopped peanut butter cups.

In a separate bowl, using an electric mixer, combine the peanut butter, powdered sugar, and softened butter until smooth.

Transfer chocolate batter and peanut butter batter to prepared baking dish dropping large spoonfuls in an alternating fashion. Using a the tip of a butter knife, swirl the two batters together. Using a rubber spatula, fill in the corners of the pan – it doesn’t have to be perfect. Top with additional chopped peanut butter cups, if desired

Bake in preheated oven until an inserted toothpick comes out clean, 35 to 40 minutes. Remove, and cool pan on wire rack before cutting.
