Reese's Brownies with Peanut Butter Buttercream
Author: Nikki
The perfect dessert for chocolate peanut-butter lovers!
  • 1 box of your favorite brownie mix, prepared according to package directions or you can use your favorite brownie recipe. I love my mom's brownie recipe found HERE
  • 24 Mini Reese's Peanut Butter cups, unwrapped
  • ½ cup butter, softened
  • 3 cups powdered sugar
  • 1 tsp. vanilla
  • 3 Tbsp. milk, more if needed to reach desired consistency
  • ¼ cup peanut butter
  • 7 Mini Reese's Peanut Butter cups, unwrapped and chopped
  1. Preheat oven to 350 degrees F.
  2. Prepare brownies as directed on packaged.
  3. Spray a 9x13 with cooking spray and spread half of the brownie batter on the bottom.
  4. Place align unwrapped Mini Reese's cups 6x4 evenly across pan (6 down by 4 across).
  5. Carefully spread remaining half of brownie batter over the top. I find it easiest to drop by spoonfuls evenly over the top and then spread to connect the spoonfuls evenly.
  6. Bake at 350 degrees F for 20-25 minutes (or how every long your package specifies) or until batter is cooked through and toothpick comes out clean. Don't overcook and make sure to do the toothpick test in the batter and not a Reese's cup :)
  7. Let cool completely.
  8. While brownies are cooling, make Peanut Butter Buttercream Frosting. To make: Beat butter, powdered sugar, vanilla, milk and peanut butter until smooth or creamy. Add more powdered sugar/milk to reach desired consistency.
  9. Spread frosting over cooled brownies and top with chopped Mini Reese's cups.
