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 & Topping

  • 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
  • 2 tablespoons creamy peanut butter (for drizzle)

Instructions

  1. Preheat Oven: Set your oven to 350°F (175°C) and line a 9 x 13-inch baking pan with parchment paper to prevent sticking and allow easy removal of the bars.
  2. Prepare the Crust: Crush 32 Nutter Butter cookies into fine crumbs using a food processor, blender, or place them in a zip-top bag and crush with a rolling pin until you get about 4 cups of crumbs. In a large bowl, mix the cookie crumbs with brown sugar and salt. Pour in the melted butter and stir thoroughly. Press the crumb mixture evenly into the bottom of the prepared pan using a glass or the bottom of a flat measuring cup to create a compact crust layer.
  3. Make the Filling: In a microwave-safe bowl, melt 1/4 cup of creamy peanut butter for about 30 seconds until smooth. Stir in the entire can of sweetened condensed milk until fully combined and creamy.
  4. Assemble the Bars: Sprinkle peanut butter chips and roasted peanuts evenly over the crust. Pour the peanut butter and condensed milk mixture over these toppings. Next, distribute the chopped Nutter Butter cookies and Reese’s Pieces candy across the filling. Using a spatula or fork, gently press all toppings into the peanut butter mixture so they stick together. If desired, sprinkle with flaky sea salt for an added flavor contrast.
  5. Bake: Place the pan in the oven and bake for 30 to 35 minutes or until the edges turn golden brown and the filling is set. Remove the pan and allow it to cool on a wire rack completely. Then refrigerate the bars to chill and firm up further.
  6. Serve: Just before serving, melt 2 tablespoons of creamy peanut butter in the microwave and drizzle it generously over the chilled bars for an extra peanut butter kick and attractive finish.

Notes

  • For best results, ensure the crumb crust is firmly pressed to avoid crumbling when cutting the bars.
  • You can substitute Reese’s Pieces with other peanut butter candies or chocolate chips if preferred.
  • Chilling the bars overnight enhances the flavor and texture.
  • The flaky sea salt is optional but highly recommended to balance the sweetness with a subtle salty crunch.
  • Use parchment paper with overhang to lift bars easily out of the pan for clean slicing.
