These chewy peanut butter cup cookie bars feature a gooey, peanut buttery base with melty chocolate chunks, perfect for a quick and easy homemade treat.

Ingredients

Scale
  • 1 cup creamy peanut butter
  • 3/4 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1/2 cup (1 stick) unsalted butter, softened
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup chocolate chunks (mix of bittersweet and milk chocolate)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan or line it with parchment paper, leaving some overhang for easy removal.
  2. In a large bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar using an electric mixer on medium speed for 2-3 minutes until light and fluffy.
  3. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed or folding gently with a spatula until just combined. Avoid overmixing.
  6. Fold in the chocolate chunks carefully to distribute evenly without breaking them up.
  7. Transfer the dough into the prepared baking pan and spread evenly with a spatula.
  8. Bake for 20-25 minutes, checking at 20 minutes with a toothpick. It should come out with a few moist crumbs but no wet batter.
  9. Allow the cookie bars to cool completely in the pan, about 30 minutes.
  10. Lift the bars out using the parchment paper overhang and cut into squares or rectangles.

Notes

Do not overmix the dough after adding flour to keep bars chewy. Use room temperature ingredients for best results. Softened butter is preferred over melted for lighter texture. Cool bars completely before cutting to prevent crumbling. Adjust baking time slightly based on oven temperature. For gluten-free, substitute flour with gluten-free blend and add almond flour for chewiness. For dairy-free, use coconut oil instead of butter and dairy-free chocolate chunks.
