Ingredients

Scale

Wet Ingredients

  • 1 cup unsalted butter (softened to room temperature)
  • 1 cup creamy peanut butter
  • 1½ cups light brown sugar (tightly packed)
  • ½ cup granulated sugar
  • 1 large egg
  • 1 large egg yolk
  • 2 teaspoons vanilla extract
  • 2 tablespoons milk

Dry Ingredients

  • 2¾ cups all-purpose flour
  • 1 teaspoon cornstarch
  • ½ teaspoon baking powder
  • ¼ teaspoon salt

Add-ins

  • 2 cups chocolate chips (semisweet or milk chocolate)

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease and flour the pan to prevent sticking.
  2. Cream butter, peanut butter, and sugars: In a large mixing bowl, use a hand mixer to cream together the softened unsalted butter, creamy peanut butter, light brown sugar, and granulated sugar until the mixture is light and fluffy, ensuring even incorporation of ingredients.
  3. Add eggs and vanilla: Beat in the large egg, egg yolk, and vanilla extract to the creamed mixture, mixing thoroughly to blend all wet ingredients smoothly.
  4. Combine dry ingredients: In a separate medium bowl, whisk together all-purpose flour, cornstarch, baking powder, and salt until well combined to ensure even distribution of leavening and seasoning.
  5. Mix dry into wet ingredients: Gradually add the dry ingredient mixture to the wet ingredients, mixing steadily until fully combined and a consistent dough forms with no streaks of flour.
  6. Add milk and stir: Pour in the milk and stir the batter again until the moisture is evenly absorbed and the dough achieves the desired softness and consistency.
  7. Fold in chocolate chips: Gently fold in the chocolate chips with a spatula, distributing them evenly throughout the dough without overmixing to avoid melting.
  8. Transfer and spread batter in pan: Transfer the cookie dough to the prepared pan. Use a spatula to spread it evenly and smooth the surface for uniform baking.
  9. Bake: Bake in the preheated oven for 35 to 40 minutes, or until the edges turn just golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs attached.
  10. Cool and serve: Allow the cookie bars to cool completely in the pan on a wire rack before slicing into bars and serving to ensure they set properly.

Notes

  • For a nuttier flavor, you can use crunchy peanut butter instead of creamy.
  • If you prefer, substitute milk with almond milk or another dairy-free alternative.
  • Use semisweet or milk chocolate chips depending on your sweetness preference.
  • Make sure the butter is softened, not melted, for better texture in the bars.
  • Store cooled bars in an airtight container at room temperature for up to 4 days or refrigerate for up to a week.
