Ingredients

  • 1 cup salted butter melted, room temperature
  • 1 cup creamy peanut butter not natural style
  • 1 ½ cups light brown sugar
  • ½ cup granulated sugar
  • 2 tsp vanilla extract
  • 2 ⅓ cup all-purpose flour
  • 1 tsp baking soda
  • 1 tsp baking powder
  • ½ tsp kosher salt
  • 1 cup Reese's Pieces
  • extra Reese's Pieces for topping

Instructions

  • In a large bowl, whisk together melted butter and peanut butter until smooth. Add brown sugar and granulated sugar and mix until fully combined. Add eggs, egg yolk and vanilla. Mix until smooth.
  • Stir in flour, baking soda, baking powder and salt. Mix just until combined. Do not over mix. Fold in Reese's Pieces, cover and chill dough for 30-45 minutes.
  • Preheat the oven to 350℉ while the cookie dough is chilling. Bake for 11–12 minutes, until edges are set and centers look slightly underbaked. Immediately press more Reese's Pieces into the tops. Let cookies cool on the baking sheet for 10 minutes before transferring to a wire rack.
