Ingredients

  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon fine sea salt
  • 1/2 cup unsalted butter , softened
  • 1/2 cup creamy peanut butter
  • 3/4 cup sugar
  • 3/4 cup light brown sugar , packed
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/2 cups peanut butter chips
  • 1 1/2 cups semi-sweet chocolate chips

Instructions

  • Preheat the oven to 375°F. Line a 9x13 baking pan with parchment paper and set aside.
  • Sift together the flour, baking powder, and salt, set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment or a large mixing bowl using an electric hand mixer, cream together the butter and peanut butter until smooth.
  • Add the sugar and brown sugar to the bowl and mix until combined. Add the eggs, one at a time, until fully mixed. Add the vanilla, mixing again.
  • Add the dry mixture slowly and blend until just mixed. Fold in the chocolate chips and peanut butter chips by hand.
  • Press the cookie dough into the prepared baking pan. Bake for 25-30 minutes or until it passes the toothpick test. If you like them chewy, cook for 5 minutes less.
  • Let the bars cool completely on a wire cooling rack, then lift the bars out using the parchment paper as a sling. Cut into bars and serve.
