Nutter Butter Bars Recipe
Introduction
Nutter Butter Bars are a decadent treat that combine the crunchy, peanut buttery flavor of classic Nutter Butter cookies with a rich, creamy filling. Perfect for peanut butter lovers, these bars are easy to make and irresistibly delicious.

Ingredients
- 32 Nutter Butter cookies (approx. 4 cups crumbs)
- 1/2 cup melted butter
- 2 tablespoons brown sugar
- 1/4 teaspoon salt
- 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 drizzling)
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Line a 9 x 13 inch baking pan with parchment paper for easy removal.
- Step 2: Crush 32 Nutter Butter cookies into fine crumbs using a food processor, blender, or by placing them in a zip-top bag and rolling with a pin. In a large bowl, combine the cookie crumbs, brown sugar, and salt. Pour in the melted butter and stir until the mixture is evenly moistened. Press this crust mixture firmly into the bottom of the prepared pan.
- Step 3: In a medium microwave-safe bowl, melt 1/4 cup of creamy peanut butter for about 30 seconds. Stir in the sweetened condensed milk until fully combined to create the filling.
- Step 4: Evenly sprinkle the peanut butter chips and roasted peanuts over the pressed crust. Pour the peanut butter and condensed milk mixture over the toppings. Scatter the chopped Nutter Butter cookies and Reese’s Pieces candy on top. Gently press everything into the filling using a spatula or fork so it sticks together. If you like, sprinkle flaky sea salt over the top for an extra flavor pop.
- Step 5: Bake the bars for 30 to 35 minutes, or until the edges turn golden brown. Remove from the oven and place the pan on a wire rack to cool completely. Once cooled, chill the bars in the refrigerator to set.
- Step 6: Before serving, melt 2 tablespoons of creamy peanut butter in the microwave and drizzle it over the chilled bars for a finishing touch.
Tips & Variations
- For a crunchier crust, toast the cookie crumbs lightly before mixing with butter.
- Substitute Reese’s Pieces with chopped peanut butter cups or your favorite candy for variation.
- If you prefer a less sweet bar, reduce the brown sugar slightly in the crust.
- Use crunchy peanut butter in the filling for added texture.
Storage
Store the Nutter Butter Bars in an airtight container in the refrigerator for up to one week. For longer storage, freeze the bars for up to 2 months. To enjoy after freezing, thaw in the refrigerator and add the peanut butter drizzle before serving. These bars are best served chilled but can be left at room temperature for about 30 minutes before eating to soften slightly.

FAQs
Can I use another type of cookie instead of Nutter Butters?
Yes, you can substitute similar peanut butter cookies or even graham crackers, but the unique flavor of Nutter Butters really complements the bars best.
Is it necessary to chill the bars before serving?
Chilling helps the bars set and hold together better, especially because of the sweetened condensed milk filling. Serving chilled also improves the texture and flavor balance.

Ingredients
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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
