Ingredients

Scale

Brownie Batter

  • ½ cup salted butter (melted and cooled)
  • 1 ½ cups granulated sugar
  • 2 teaspoons vanilla extract
  • 3 large eggs
  • ¾ cup all-purpose flour
  • ½ cup unsweetened cocoa powder
  • ½ teaspoon salt
  • ½ teaspoon baking powder

Filling

  • 24 full-size chocolate peanut butter cups

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) to prepare for baking the brownies.
  2. Prepare the Pan: Line a 9×13 inch rectangular baking pan with parchment paper and spray with nonstick cooking spray to prevent sticking.
  3. Mix Butter and Sugar: Using a hand mixer or standing mixer, beat together the melted and cooled butter with granulated sugar until creamy and combined.
  4. Add Vanilla and Eggs: Mix in the vanilla extract. Then add eggs one at a time, beating well after each addition to ensure a smooth mixture.
  5. Sift Dry Ingredients: Sift together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder to avoid lumps and promote even mixing.
  6. Combine Mixtures: Gradually add the dry ingredients into the wet butter and sugar mixture. Beat until the batter is fully combined and thick.
  7. First Layer of Batter: Spread half of the thick brownie batter evenly across the bottom of the prepared pan, using a spatula to cover the entire surface carefully.
  8. Add Peanut Butter Cups: Arrange the 24 full-size chocolate peanut butter cups neatly in rows on top of the batter to create a hidden filling layer.
  9. Top Layer of Batter: Spread the remaining half of the brownie batter evenly over the peanut butter cups, smoothing the surface to ensure complete coverage.
  10. Bake: Place the pan in the preheated oven and bake for 30 minutes. The brownies should be set in the middle, and a toothpick inserted in the center should come out with a few moist crumbs.
  11. Cool: Remove the brownies from the oven and allow them to cool completely in the pan to set properly.
  12. Serve: Lift the cooled brownies out of the pan using the edges of the parchment paper. Cut into pieces and serve your delicious peanut butter cup brownies.

Notes

  • Make sure the melted butter is cooled before mixing with sugar to prevent cooking the eggs.
  • Use parchment paper for easy removal of brownies from the pan.
  • For cleaner cuts, chill the baked brownies before slicing.
  • You can substitute salted butter with unsalted if preferred, adjusting salt accordingly.
  • Check the brownies early if your oven runs hot to avoid overbaking.
