Instructions

  1. Step 1: Preheat oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. Step 2: In a large bowl, cream together 1/2 cup softened unsalted butter, 1/2 cup granulated sugar, 1/2 cup packed brown sugar, and 3/4 cup creamy peanut butter using an electric mixer on medium speed until smooth and fluffy, about 2 minutes.
  3. Step 3: Beat in 1 large egg and 1 tsp vanilla extract until fully incorporated.
  4. Step 4: In a separate bowl, whisk together 1 1/4 cups all-purpose flour, 1/2 tsp baking soda, and 1/4 tsp salt.
  5. Step 5: Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.
  6. Step 6: Fold in 3/4 cup semi-sweet chocolate chips evenly throughout the batter.
  7. Step 7: Spread the batter evenly into the prepared pan, smoothing the top with a spatula.
  8. Step 8: Bake for 22-25 minutes until the edges are set and a toothpick inserted into the center comes out with moist crumbs.
  9. Step 9: Allow to cool completely in the pan on a wire rack before lifting out using the parchment paper and cutting into bars.
