Delight in these soft and chewy Peanut Butter Cookie Bars, a perfect blend of creamy peanut butter and sweet brown sugar, enhanced with optional semi-sweet chocolate chips. Baked to golden perfection, these bars make a deliciously easy dessert or snack that everyone will love.


Ingredients

Scale

Butter and Peanut Butter Mixture

  • 1/2 cup unsalted butter (softened)
  • 1/2 cup creamy peanut butter
  • 1 cup packed light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt

Optional Add-in

  • 1/2 cup semi-sweet chocolate chips


Instructions

  1. Preheat the oven: Set your oven to 350°F (175°C) and grease or line an 8×8-inch baking pan with parchment paper to prevent sticking.
  2. Cream the wet ingredients: In a large bowl, beat the softened butter, peanut butter, and brown sugar together until the mixture is smooth and fluffy. Add the egg and vanilla extract, mixing thoroughly until combined.
  3. Combine dry ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt to ensure even distribution.
  4. Mix wet and dry ingredients: Gradually add the dry ingredients to the wet mixture, stirring just until combined to keep the batter tender. Fold in the chocolate chips if using.
  5. Prepare to bake: Spread the cookie dough evenly into the prepared baking pan, smoothing the top with a spatula.
  6. Bake: Place in the oven and bake for 22–25 minutes or until the top is golden and a toothpick inserted in the center comes out with a few moist crumbs.
  7. Cool and serve: Allow the bars to cool completely in the pan before cutting into 16 squares for serving.

Notes

  • For an intensified peanut butter flavor, consider drizzling melted peanut butter over the bars before serving.
  • If doubling the recipe to fit a 9×13-inch pan, extend the baking time by 5 to 7 minutes to ensure proper cooking.
