How to Make Kelsey's Peanut Butter Bars

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a medium bowl, whisk together 1 ½ cups all-purpose flour, 1 teaspoon baking powder, and ½ teaspoon salt. Set aside.
  3. In a large bowl, cream together 1 cup creamy peanut butter and ½ cup (1 stick) unsalted butter until light and fluffy.
  4. Gradually add 1 cup granulated sugar and ¾ cup packed brown sugar, mixing well after each addition.
  5. Beat in 2 large eggs one at a time, then stir in 1 teaspoon vanilla extract.
  6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
  7. Pour batter into the prepared pan and spread evenly.
  8. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  9. Let the bars cool completely in the pan before adding the icing.
  10. **Icing:** In a medium bowl, combine 1 cup powdered sugar, 2 tablespoons milk, 2 tablespoons peanut butter, and ¼ teaspoon vanilla extract. Mix until smooth and creamy.
  11. Spread the icing evenly over the cooled peanut butter bars.
  12. Cut into squares and enjoy!
