these peanut butter chocolate chip cookie bars combine two of the best flavors together for an easy, one-bowl dessert that everyone is sure to love.


  • 1 cup (2 sticks) unsalted butter, room temperature or softened
  • 1 cup + 2 tablespoons granulated sugar
  • 2 eggs
  • 2 teaspoons vanilla
  • 3/4 cup unsalted creamy peanut butter (see note)
  • 2 1/4 cup unbleached all-purpose flour
  • 2 teaspoons baking soda
  • 1/4 teaspoon salt
  • 1 cup chocolate chips


  1. Preheat the oven to 350 degrees F and grease a 9×13 inch baking pan.
  2. In a large mixing bowl, add room temperature (or softened) butter and sugars.  Use an electric hand mixer or a stand mixer and cream together until light and fluffy (about 1-2 minutes).
  3. Add in eggs, one at a time beating each for 30 seconds.
  4. Add in vanilla and peanut butter and beat for another minute or until combined.
  5. Place a wire sifter over the large mixing bowl containing the wet ingredients.  Into the sifter add flour, baking soda and salt.
  6. Sift into the wet ingredients then use a rubber spatula and gently fold together until just combined (it’s okay if a few flour chunks remain).
  7. Fold in chocolate chips, stirring until no more flour chunks remain then turn dough out into prepared baking pan and use the spatula to evenly spread throughout the pan.
  8. Bake for 20-22 minutes or until edges are lightly browned and a knife inserted in the center comes out clean.


  • If using natural peanut butter, ensure it has been stirred and refrigerated so that the oil is not separated out from the nuts.
  • Bars will keep for about 3 days in an airtight container on the counter or 3 months in a freezer safe bag in the freezer.
