Rich and decadent, Reese's Peanut Butter Cup Brownies are a dream dessert. With creamy peanut butter mixed into the fudgy batter and tons of peanut butter cups on top, the combination of flavors is irresistible and incredibly satisfying.

Instructions
 

Peanut Butter Cup Brownies

  • Preheat oven to 350 degrees. Line an 8 x 8 metal baking pan with parchment paper and set aside.
  • In a large bowl, whisk together melted butter, both sugars, vanilla and peanut butter until combined.
  • Add eggs, one at a time, whisking vigorously after each addition until well incorporated.
  • Stir in cocoa powder, salt, and flour until *just* combined.
  • Spoon batter into parchment-lined baking pan then level the top with a spatula.
  • Bake for 25 minutes or until a tester inserted into center of brownies comes out with a few moist crumbs. Do not overbake or brownies will be dry.
  • Remove pan from the oven and place on a wire rack to cool.
  • Remove wrappers from peanut butter cups. After brownies have cooled for 10 minutes, gently push peanut butter cup bottoms into the brownie crust.
  • Allow brownies to cool to completely at room temperature before slicing.
    *If the peanut butter cups are still a bit melty after brownies have cooled, refrigerate a few minutes until firm.
  • If desired, sprinkle peanut butter cups with sea salt.
  • Cover and store leftovers at room temperature up to 1 week.
