The BEST Nutter Butter Bars Ingredients
For the Crust
- Nutter Butter cookies – The base for the crust that provides a unique peanut butter flavor; substitute with similar sandwich cookies if needed.

- Brown sugar – Adds sweetness and moisture, enhancing the flavor depth; white sugar works in a pinch.
- Salt – Balances sweetness and enhances flavors; flaky sea salt is preferable for texture.
For the Filling
- Sweetened condensed milk – Ensures creaminess in the filling; swap with coconut milk for a non-dairy version, but expect texture changes.

- Chopped Nutter Butters – Enhances the texture when added to the topping; additional peanut butter cookies can work as substitutes.

Step‑by‑Step Instructions for The BEST Nutter Butter Bars
Step 1: Preheat & Prepare Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms, line a 9×13-inch baking pan with parchment paper, allowing the edges to hang over for easy removal later. This will help ensure your Nutter Butter Bars come out perfectly without sticking to the pan.
Step 2: Make the Crust
Crush 32 Nutter Butter cookies into fine crumbs using a food processor or a rolling pin. In a mixing bowl, combine the cookie crumbs with brown sugar and a pinch of salt, then drizzle in the melted butter. Mix thoroughly until the crumbs are well coated, then press this mixture firmly into the bottom of the prepared pan to form a solid crust.
Step 3: Prepare the Filling
In a microwave-safe bowl, melt ¼ cup of creamy peanut butter for about 20-30 seconds until just soft. Stir in a can of sweetened condensed milk until smooth and well combined. The filling should be rich and creamy, ready to add a delicious layer on top of your crust in the next step.
Step 4: Assemble Bars
Sprinkle peanut butter chips and roasted peanuts evenly over the pressed crust. Carefully pour the rich peanut butter filling on top, spreading it out to create an even layer. To finish, add chopped Nutter Butters and Reese’s Pieces on top, gently pressing them into the filling to ensure an even distribution for each bite of The BEST Nutter Butter Bars.
Step 5: Bake
Place your assembled bars in the preheated oven and bake for 30-35 minutes. Keep an eye out for the edges turning golden brown, which signals they are nearly done. Once baked, remove the pan from the oven and set it on a wire rack to cool completely, allowing the filling to set perfectly.
Step 6: Finish & Serve
After cooling, drizzle any remaining melted peanut butter over the top of the bars for an extra treat. Cut into squares or bars, and enjoy the delightful blend of flavors and textures that make The BEST Nutter Butter Bars irresistible. Serve them fresh or chill in the refrigerator for a firmer texture.
