How to Make Peanut Butter Cake Bars

  1. Preheat oven to 350°F (175°C). Grease a 13x9 inch baking pan.
  2. In a large bowl, cream together 1 cup (2 sticks) unsalted butter, 1 cup creamy peanut butter, 1 ½ cups granulated sugar, and ¾ cup packed brown sugar until light and fluffy.
  3. Add 2 large eggs one at a time, beating well after each addition.
  4. Beat in 1 teaspoon vanilla extract.
  5. In a separate bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and ½ teaspoon salt.
  6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
  7. Stir in 1 cup semi-sweet chocolate chips.
  8. Spread the batter evenly into the prepared baking pan.
  9. Bake for 45-50 minutes, or until a wooden skewer inserted into the center comes out clean.
  10. Let the bars cool completely in the pan on a wire rack before cutting into bars.
