Ingredients

Scale

Brownie Batter

  • 1 cup unsalted butter (melted)
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons vanilla extract
  • 4 large eggs
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup peanut butter cups (chopped)

Peanut Butter Swirl

  • 1/3 cup creamy peanut butter (melted)

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line it with parchment paper to ensure easy removal of the brownies once baked.
  2. Melt Butter and Mix with Sugar: In a medium saucepan over medium heat, melt the butter. Remove from heat and immediately stir in the granulated sugar and unsweetened cocoa powder until the mixture is smooth and well combined.
  3. Add Eggs and Vanilla: Stir in the vanilla extract. Then add the eggs one at a time, beating well after each addition to create a smooth, glossy batter.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this dry mix into the wet ingredients, stirring gently until just combined—be careful not to overmix.
  5. Fold in Peanut Butter Cups: Gently fold the chopped peanut butter cups into the brownie batter, making sure they are evenly distributed throughout.
  6. Pour Batter and Add Peanut Butter Swirl: Pour the batter into the prepared baking pan, spreading it evenly. Drizzle the melted creamy peanut butter over the top and use a knife or skewer to swirl it into the batter, creating a marbled effect.
  7. Bake: Place the pan in the preheated oven and bake for 25-30 minutes. To check doneness, insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter.
  8. Cool and Serve: Allow the brownies to cool completely in the pan on a wire rack before slicing into squares. Serve and enjoy your rich peanut butter cup brownies!

Notes

  • For extra fudgy brownies, avoid overbaking; remove them as soon as a toothpick comes out with moist crumbs.
  • Use parchment paper with overhang for easy lifting and removal from the pan.
  • You can substitute peanut butter cups with chopped peanut butter chocolates or Reese’s candies if preferred.
  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
