Ingredients
  

Base Ingredients

  • 1 cup unsalted butter, softened Forms the rich base of the bars.
  • 1 cup granulated sugar Adds sweetness to the bars.
  • 1 cup brown sugar, packed Contributes a deeper flavor and moisture.
  • 1 cup creamy peanut butter Gives the bars their signature flavor.
  • 2 large eggs Acts as a binder for the bars.
  • 2 teaspoons vanilla extract Enhances the flavor.

Dry Ingredients

  • 2 cups all-purpose flour Provides structure to the bars.
  • 1 teaspoon baking powder Helps the bars rise slightly.
  • 1/2 teaspoon salt Enhances flavors.

Topping Ingredients

  • 1 cup semi-sweet chocolate chips For the luscious topping.
  • 1/4 cup creamy peanut butter (for topping) Adds an additional layer of flavor.

Instructions
 

  • Preheat your oven to 350°F (175°C). Prepare a 9x13 inch baking pan by greasing it lightly or lining it with parchment paper.
  • Cream together the softened butter, granulated sugar, and brown sugar until smooth and fluffy (2-3 minutes).
  • Add the creamy peanut butter and mix until fully incorporated.
  • Crack in the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
  • In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add to the wet ingredients, mixing on low speed until just combined.
  • Pour the batter into the prepared baking pan and spread evenly.
  • Bake for 25-30 minutes, or until edges pull away and a toothpick comes out clean.
  • While baking, prepare the chocolate topping by melting the chocolate chips and 1/4 cup peanut butter in a microwave-safe bowl.
  • Once the bars are done, let them cool for 10-15 minutes, then pour the melted chocolate mixture over the top.
  • Allow to cool completely, then refrigerate for at least 1 hour to set.
  • Remove from the pan and cut into squares or rectangles. Serve and enjoy!

Notes

For variations, consider using crunchy peanut butter, adding chocolate chips to the batter, or drizzling with white chocolate.
