Ingredients

Cookie Dough

  • 6 tablespoons salted butter, at room temperature
  • 1/2 cup creamy peanut butter
  • 1/4 cup dark brown sugar
  • 2 teaspoons vanilla extract
  • 1 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • Flaky sea salt (optional)

Peanut Butter Filling

  • 3/4 cup creamy peanut butter
  • 6 tablespoons salted butter, at room temperature
  • 3-4 tablespoons honey

Instructions

  1. Prepare and preheat: Preheat your oven to 350 degrees Fahrenheit. Line an 8x8 inch square baking pan with parchment paper to prevent sticking and ease removal after baking.
  2. Make the cookie dough: In a large mixing bowl, cream together 6 tablespoons of butter, 1/2 cup peanut butter, dark brown sugar, and vanilla extract until the mixture is smooth and creamy. Then, add the flour and baking powder, beating until combined and the dough begins to come together in a ball. If the dough is crumbly, gradually incorporate 2-3 teaspoons of water to help it bind; if it feels too moist, add 1-2 tablespoons more flour to achieve the right consistency.
  3. Form the base layer: Press half of the cookie dough evenly into the prepared baking pan, smoothing it out to create an even base layer.
  4. Prepare the peanut butter filling: In a separate bowl, beat together 3/4 cup peanut butter, 6 tablespoons of butter, and 3 to 4 tablespoons honey until the mixture is smooth and well combined.
  5. Assemble the layers: Spread the peanut butter filling evenly over the cookie dough base in the pan. Then, crumble the remaining cookie dough over the top of the filling, distributing it as evenly as possible to create a crumbly top layer.
  6. Bake: Place the pan in the preheated oven and bake for 25 minutes, or until the top is set and lightly golden. If desired, immediately sprinkle flaky sea salt over the warm bars for a flavor contrast.
  7. Cool and serve: Allow the bars to cool completely in the pan before carefully cutting into 16 bars. Handle gently as they are on the crumbly side. Enjoy your rich and delicious Nutter Butter Cookie Bars!

Notes

  • Ensure butter is at room temperature for easy creaming and better texture.
  • If the dough is too dry or crumbly, add a small amount of water to help it come together.
  • For a stronger peanut butter flavor, use natural creamy peanut butter without added sugar.
  • Sprinkling flaky sea salt is optional but enhances the overall flavor by balancing the sweetness.
  • Use parchment paper to avoid sticking and make bar removal easier.
  • Bars are delicate; handle with care when cutting and serving.
