Ingredients

The following ingredients have 9 Servings
  • 2 1/2 cups all-purpose flour
  • 2 tsp baking powder
  • 1/4 tsp salt
  • 1 cup (2 sticks) unsalted butter, room temperature
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 2 tsp vanilla
  • 1 cup Reese's Pieces candy
  • 3/4 cup peanut butter chips ((or chocolate if you prefer))
  • 1/2 cup (1 stick) unsalted butter, room temperature
  • 1/4 cup cocoa powder
  • 2 1/2 cups confectioners' sugar
  • 1-2 Tbsp whole milk

Instruction

  • Pre-heat oven to 350 degrees. Line a 9-inch cake pan with parchment paper.
  • In a medium bowl, whisk together flour, baking powder, and salt.
  • In the bowl of a stand mixer or in a large bowl with a hand mixer, cream together butter and both sugars until light and fluffy.
  • Add eggs and vanilla and mix to combine.
  • Add the flour mixture to the wet ingredients and mix until just combined.
  • Fold in the Reese's Pieces and peanut butter chips.
  • Press cookie dough into the prepared pan, as evenly as possible.
  • Bake at 350 degrees for 22-25 minutes, until edges are turning golden, but cookie is still nice and gooey in the middle.
  • Remove from oven and set on a wire rack to cool. Once cooled, use a knife to loosen edges of cookie and turn out onto a cake plate or platter.
  • Put frosting in a pastry bag and pipe along the edges. Add additional Reese's Pieces if desired.
