Introduction
Nutter Butter Bars are a peanut butter lover’s dream—rich, chewy, and packed with the nostalgic flavor of Nutter Butter cookies and Reese’s Pieces. These bars combine a crunchy cookie crust with a creamy peanut butter filling and a delightful candy topping, making them irresistible treats perfect for any occasion.

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 to prevent sticking.
- Step 2: Make the crust by crushing 32 Nutter Butter cookies into 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. Stir in the melted butter until the mixture is well combined. Press the crumbs firmly into the bottom of the prepared pan using a glass or flat-bottomed measuring cup.
- Step 3: Prepare the filling by microwaving 1/4 cup creamy peanut butter in a medium microwave-safe bowl for about 30 seconds until melted. Stir in the sweetened condensed milk until smooth and fully combined.
- Step 4: Sprinkle the peanut butter chips and roasted peanuts evenly over the crust. Pour the peanut butter and condensed milk mixture on top, spreading it gently. Add the chopped Nutter Butter cookies and Reese’s Pieces candy. Using a spatula or fork, gently press the toppings into the filling so they stick. If desired, sprinkle with flaky sea salt for a hint of savory contrast.
- Step 5: Bake the bars for 30 to 35 minutes, or until the edges turn golden brown. Remove from the oven and transfer the pan to 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 bars for an extra peanut buttery finish.
Tips & Variations
- For a crunchier texture, toast the roasted peanuts lightly before adding them on top.
- Substitute Reese’s Pieces with chocolate chips or M&Ms for a colorful twist.
- If you prefer a thicker crust, use 40 cookies instead of 32 for the base.
- Use natural peanut butter for a more intense peanut flavor, but note the texture may be different.
Storage
Store the Nutter Butter Bars in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze the bars for up to 2 months, thawing them in the fridge before serving. Reheat slightly in the microwave if you prefer a softer texture.

FAQs
Can I use a different type of cookie instead of Nutter Butters?
While Nutter Butter cookies provide a distinct peanut flavor, you can substitute with other peanut butter-flavored cookies or graham crackers for a different texture and taste.
Is it necessary to chill the bars after baking?
Yes, chilling helps the bars set firmly, making them easier to cut and enhancing their chewy texture. However, you can enjoy them slightly warm if preferred.
