Step‑by‑Step Instructions for Nutter Butter Peanut Butter Cookie
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial to ensure the Nutter Butter Peanut Butter Cookies bake evenly and achieve the perfect chewy texture. While the oven heats up, gather your mixing bowl and beaters to make the cookie dough.
Step 2: Combine the Ingredients
In a mixing bowl, combine the low carb peanut butter, egg, Swerve confectioners sugar substitute, and vanilla extract. Using an electric mixer, beat these ingredients on medium speed until the mixture is smooth and creamy, about 2 minutes. The batter should be thick enough to form shapes, signaling it’s ready for the next step.
Step 3: Shape the Cookies
Once your dough is mixed, divide it into 20 equal pieces. Roll each piece into an oblong shape, pinching the center to create the iconic peanut shape. Set each shaped cookie onto a parchment-lined baking sheet, leaving a little space between them to allow for spreading as they bake.
Step 4: Create the Criss-Cross Pattern
Take a fork and gently press down on each cookie to create a criss-cross pattern on top. This not only adds a decorative touch but also helps the Nutter Butter Peanut Butter Cookies cook uniformly. Make sure to apply gentle pressure to maintain their shape.
Step 5: Bake the Cookies
Place the baking sheet in your preheated oven and bake for 10-12 minutes. Keep an eye on them—you’re looking for a golden color and the edges set, indicating they’re ready. Once baked, remove them from the oven and allow the cookies to cool on the sheet for a few minutes before transferring to a wire rack.
Step 6: Prepare the Cookie Filling
While the cookies cool, prepare the filling. In a clean mixing bowl, mix the low carb peanut butter, softened butter, Swerve confectioners sugar substitute, and a splash of vanilla extract. Blend until it reaches a creamy consistency, which should take about 2 minutes, ensuring it’s smooth and luscious.
Step 7: Assemble the Cookies
Spread a generous amount of the creamy filling on the flat bottom of one cookie, then top it with another cookie, flat side down, to create a sandwich. Press gently to secure the filling inside. Repeat this process with all cookies to assemble your delightful Nutter Butter Peanut Butter Cookies.
Step 8: Chill the Cookies
Finally, to help the filling set and maintain shape, place the assembled cookies in the freezer for 30 minutes. This brief chilling time solidifies the filling, making each bite of your Nutter Butter Peanut Butter Cookie an irresistible indulgence. After chilling, they’re ready to serve!

Tips for the Best Nutter Butter Peanut Butter Cookies
-
Measure Carefully: Always measure your low carb peanut butter accurately; too much can make your dough overly sticky or spread too much during baking.
-
Chill Dough: For perfectly shaped cookies, chill the dough for 15 minutes before shaping; this helps the Nutter Butter Peanut Butter Cookies hold their form.
-
Use Parchment Paper: Line your baking sheet with parchment paper to prevent sticking and ensure even baking for every cookie.
-
Don’t Overbake: Keep an eye on the cookies during the last couple of minutes; they continue to cook slightly as they cool, so remove them when they’re just golden.
-
Filling Consistency: Make sure your filling is creamy, not runny; this ensures it stays inside the cookies without spilling out.
-
Experiment with Flavors: Feel free to try different nut butters or flavored extracts to make unique Nutter Butter Peanut Butter Cookies that match your taste preferences!

- Freezer: To preserve them even longer, freeze the assembled cookies for up to 2 months. Place them in a single layer in a freezer-safe container with parchment paper between layers to prevent sticking.

Nutter Butter Peanut Butter Cookie Recipe FAQs
What type of nut butter should I use for these cookies?
Absolutely! While low carb peanut butter is the star ingredient, you can experiment with other nut butters like almond or cashew if you prefer a different flavor. Just ensure that any substitute you choose is also low in carbs to maintain the keto-friendly aspect of your cookies!
How should I store my Nutter Butter Peanut Butter Cookies?
For room temperature storage, keep them in an airtight container on the counter for up to 3 days. If you wish to extend their freshness, pop them in the fridge where they can last up to 1 week. For longer-term storage, freeze the cookies for up to 2 months. Just make sure to layer them with parchment paper in a freezer-safe container to prevent sticking.
Can I freeze these cookies? If so, how?
Yes, absolutely! To freeze your assembled Nutter Butter Peanut Butter Cookies, place them in a single layer in a freezer-safe container, making sure to add parchment paper between layers. This will keep them from sticking together. They can be stored for up to 2 months. When you’re ready to enjoy, just take them out and let them thaw at room temperature or microwave for a few seconds for a warm treat.
What should I do if my cookie dough is too sticky?
Very! If your dough feels too sticky, you might have added too much nut butter or not enough sweetener. Try chilling the dough in the fridge for about 15 minutes; this should help firm it up. If it remains sticky, consider adding a bit of almond flour or coconut flour, one tablespoon at a time, until the desired consistency is reached.
Are these cookies safe for people with nut allergies?
If you know someone with a nut allergy, it’s best to steer clear of these cookies altogether as they mainly use nut butters. However, for a safe alternative, you might consider experimenting with sunflower seed butter, which is often a suitable replacement in cookies for nut-free diets. Just ensure that it fits within the dietary goals you’re targeting!
What can I do if my filling is too runny?
To fix a runny filling, try adding a bit more of the Swerve confectioners sugar substitute. Start with a tablespoon and mix thoroughly until you reach the desired creamy consistency. If it’s still too soft, refrigerate the filling for about 15-30 minutes before spreading it between the cookies. This little trick will solidify the filling and keep it neatly inside!
