Ingredients

Scale

Brownie Batter

  • 1 Pillsbury family size brownie mix (19.5 ounces)
  • 1 large egg
  • 4 ounces cream cheese, softened
  • 1/4 cup salted butter, softened

Add-ins

  • 16 full-size Reese’s peanut butter cups, frozen

Peanut Butter Frosting

  • 1/2 cup salted butter, softened
  • 1 cup creamy peanut butter
  • 2 cups powdered sugar
  • 3 tablespoons 2% milk

Chocolate Drizzle

  • 2 ounces semi-sweet chocolate

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350ºF. Line an 8×8-inch baking pan with parchment paper or generously spray with cooking spray to prevent sticking.
  2. Make brownie batter: In a stand mixer or with an electric mixer, combine the brownie mix, egg, softened cream cheese, and 1/4 cup softened salted butter. Mix well until fully combined and the batter is thick. Use a rubber spatula to scrape down the sides of the bowl as needed. Spread this dense batter evenly in the prepared baking pan.
  3. Insert peanut butter cups: Press the frozen Reese’s peanut butter cups into the batter in a 4×4 grid pattern, arranging 16 cups total. Push each one gently enough so the top of the peanut butter cups sits flush with the batter surface. This layering ensures gooey chocolate and peanut butter centers.
  4. Bake the brownies: Place the pan in the preheated oven and bake for about 28 minutes. The brownies should be set and a toothpick inserted near a peanut butter cup comes out mostly clean with a few moist crumbs. Remove from oven and allow to cool completely.
  5. Prepare peanut butter frosting: While the brownies bake, blend 1/2 cup softened salted butter, 1 cup creamy peanut butter, 2 cups powdered sugar, and 3 tablespoons 2% milk in a stand mixer. Beat for 2-3 minutes until the frosting is light, fluffy, and spreadable.
  6. Frost the brownies: Once brownies are fully cooled, generously spread the peanut butter frosting evenly over the top layer.
  7. Melt chocolate for drizzle: Place 2 ounces of semi-sweet chocolate in a microwave-safe bowl and heat in 15-second intervals, stirring well between each to prevent burning. Continue until chocolate is fully melted and smooth.
  8. Drizzle and set: Drizzle the melted chocolate decoratively over the frosted brownies. Allow the chocolate to set at room temperature before slicing and serving.

Notes

  • Use frozen peanut butter cups to help them retain their shape while baking.
  • Ensure the brownies are completely cool before frosting to avoid melting the frosting.
  • If desired, substitute 2% milk in frosting with almond milk for a dairy alternative.
  • Chocolate drizzle can be replaced with chocolate chips melted with a small amount of butter for extra shine.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
