Ingredients
  

  • 1/2 cup unsalted butter melted
  • 1 cup creamy peanut butter
  • 1 cup brown sugar packed
  • 1/4 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1 cup butterscotch chips
  • 1/2 cup chocolate chips optional

Equipment

  • 9×13-inch baking dish
  • Parchment paper
  • Large mixing bowl
  • Small mixing bowl
  • whisk
  • spatula
  • Sharp knife

Method
 

  1. Preheat oven to 350°F and grease or line a 9x13-inch baking dish with parchment paper.
  2. In a large bowl, whisk together melted butter, peanut butter, brown sugar, and granulated sugar until smooth and glossy.
  3. Beat in eggs and vanilla until well combined and silky.
  4. In a separate bowl, whisk together flour, baking powder, and salt.
  5. Gently fold the dry ingredients into the wet ingredients until just combined.
  6. Fold in butterscotch chips and chocolate chips, if using.
  7. Spread the batter evenly into the prepared pan.
  8. Bake for 25 to 30 minutes, until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs.
  9. Let cool completely before slicing into bars.

Notes

Regular creamy peanut butter gives the most consistent texture.
Do not overbake; the center should stay soft and chewy.
Cool completely before cutting for clean slices.
Store in an airtight container at room temperature or in the refrigerator.
