Ingredients

The following ingredients have 4 Servings
  • 3/4 cup unsalted butter (softened)
  • 3/4 cup brown sugar (light or dark)
  • 3/4 cup white sugar
  • 1 cup smooth peanut butter* (do not use homemade or natural)
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 3/4 cup chocolate chips*
  • 3/4 cup peanut butter chips* (or replace the peanut butter chips with more chocolate chips)

Instruction

  • Preheat the oven to 350F degrees.
  • Lightly spray a 9x13 inch (23x28 cm) pan non-stick cooking spray and then with parchment paper, leaving an overhang around the edges. Lightly greasing the pan first stops the parchment from sliding around.
  • In a large bowl beat together the butter, brown sugar and white sugar until no lumps remain.
  • Beat in the peanut butter until smooth. Then mix in the eggs and vanilla extract.
  • Turn the mixer down to low speed and mix in the flour, baking powder and salt. Turn of the mixer and scrape down the sides of the bowl as needed.
  • Stir in the chocolate chips and peanut butter chips.
  • Spoon the batter into the prepared pan and smooth the top.
  • Place in the preheated oven in the middle rack and bake for 30 minutes, or until an inserted toothpick comes out clean or with a few crumbs. It may take anywhere between 25-35 minutes, depending on your oven.
  • Remove from the oven and place the pan on a wire rack to cool, keeping the bars in the pan. Cool for at least 45 minutes, or cool the pan is room temperature for clean cuts (what's pictured).
  • To slice the bars, lift them out of the pan using the parchment paper overhang. Place on a cutting board and slice. Store cooled bars in an airtight container for up to 4 days at room temperature.
