Ingredients

Scale

Crust

  • 32 Nutter Butter cookies (approx. 4 cups crumbs)
  • 1/2 cup melted butter
  • 2 tablespoons brown sugar
  • 1/4 teaspoon salt

Filling and Toppings

  • 1 can sweetened condensed milk (14 oz.)
  • 1/4 cup creamy peanut butter
  • 1 cup peanut butter chips
  • 1/2 cup roasted peanuts
  • 12 Nutter Butter cookies (chopped)
  • 3/4 cup Reese’s Pieces candy
  • Flaky sea salt, optional

Drizzle

  • 2 tablespoons creamy peanut butter

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C). Line a 9 x 13-inch baking pan with parchment paper to prevent sticking and for easy removal of the bars later.
  2. Prepare the Nutter Butter crust: Crush 32 Nutter Butter cookies into approximately 4 cups of fine crumbs using a food processor, blender, or by placing them in a zip-top bag and crushing with a rolling pin. In a large bowl, combine the cookie crumbs, brown sugar, and salt. Pour in the melted butter and stir well until all crumbs are evenly coated. Use a glass or flat-bottomed measuring cup to firmly press the crust mixture into the bottom of the prepared pan, creating an even layer.
  3. Make the peanut butter filling: In a medium microwave-safe bowl, melt 1/4 cup of creamy peanut butter by microwaving for about 30 seconds. Stir until smooth. Add the entire can of sweetened condensed milk to the melted peanut butter and mix thoroughly until fully combined.
  4. Assemble the bars: Evenly sprinkle the peanut butter chips and roasted peanuts over the crust in the pan. Pour the peanut butter and sweetened condensed milk mixture evenly on top. Next, sprinkle the chopped 12 Nutter Butter cookies and Reese’s Pieces candy over the filling. Using a spatula or fork, gently press the toppings into the peanut butter mixture to help everything stick together. If desired, sprinkle flaky sea salt on top to enhance the flavors.
  5. Bake the bars: Place the pan in the preheated oven and bake for 30 to 35 minutes, or until the edges are golden brown and the bars are set. When done, remove from the oven and transfer the pan onto a wire rack to cool completely. After cooling, chill the bars in the refrigerator to firm up.
  6. Serve with peanut butter drizzle: Before serving, melt 2 tablespoons of creamy peanut butter in the microwave until smooth and warm. Drizzle this peanut butter over the chilled bars to add an extra layer of flavor and visual appeal. Cut into 24 servings and enjoy!

Notes

  • Ensure the crust is pressed firmly for a sturdy base to hold the filling and toppings.
  • Chilling the bars before serving helps them firm up and makes cutting easier.
  • You can substitute Reese’s Pieces with other peanut butter candies or chocolate chips if preferred.
  • Store bars in an airtight container in the refrigerator for up to 5 days.
  • For a nut-free version, omit the roasted peanuts and use allergy-friendly toppings.
