Description

Peanut Butter Cookie Bars are soft, chewy dessert bars packed with sweet and nutty flavor. Baked in one pan, they deliver all the goodness of classic peanut butter cookies without the need for scooping or rolling—perfect for quick baking, lunchboxes, and peanut butter lovers everywhere.


Ingredients

  • 1 cup creamy peanut butter
  • ½ cup unsalted butter, softened
  • ¾ cup granulated sugar
  • ¾ cup brown sugar
  • 2 large eggs
  • 2 tsp vanilla extract
  • 2 cups all-purpose flour
  • 1 tsp baking powder
  • ½ tsp salt
  • Optional: 1 cup chocolate chips or chopped peanuts

Instructions

  1. Preheat oven to 350°F (175°C) and grease or line a 9x13-inch baking pan.
  2. In a large bowl, cream together peanut butter, butter, granulated sugar, and brown sugar until light and fluffy.
  3. Beat in eggs one at a time, then add vanilla extract.
  4. In a separate bowl, whisk together flour, baking powder, and salt.
  5. Gradually add dry ingredients to wet mixture, stirring until combined.
  6. Fold in chocolate chips or chopped nuts, if using.
  7. Press dough evenly into the prepared pan and smooth the top.
  8. Bake for 22–28 minutes, until golden and a toothpick inserted in the center comes out clean.
  9. Let cool completely before slicing into squares.

Notes

  • For a PB&J twist, swirl a few spoonfuls of jam over the top before baking.
  • Use crunchy peanut butter or add chopped peanuts for extra texture.
  • Top with melted chocolate or peanut butter glaze for a dessert-style finish.
  • Freeze individually wrapped bars for easy snacks later.
