Ingredients You’ll Need
Don’t be fooled by the simplicity here—all these ingredients play an essential role in crafting the perfect balance of sweetness, texture, and peanut buttery goodness in your cookies.
- Natural creamy peanut butter: Using peanut butter with no added sugar ensures a rich flavor without unwanted carbs.
- Granular erythritol or preferred keto sweetener: Provides the sweetness you want without spiking blood sugar.
- Large egg: Acts as a binder, giving the dough structure and chewiness.
- Vanilla extract: Adds a warm depth that complements the peanut butter’s nuttiness.
- Baking soda: Helps the cookies rise slightly and develop a light texture.
- Pinch of salt: Enhances all the flavors and balances the sweetness.
- Optional sugar-free chocolate chips: For a fun twist of melty pockets of chocolate without the carbs.
How to Make Keto Peanut Butter Cookies Recipe
Step 1: Preheat and Prepare
Begin by heating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This simple prep ensures your cookies won’t stick and bake evenly.
Step 2: Mix the Ingredients
In a medium bowl, combine the peanut butter, erythritol, egg, vanilla extract, baking soda, and salt. Stir gently but thoroughly until the dough is fully smooth and homogenous. If you’ve chosen to add sugar-free chocolate chips, now is the moment to fold them into that heavenly dough.
Step 3: Shape the Cookies
Using about a tablespoon of dough for each cookie, roll the mixture into balls. Place each ball on the prepared sheet with roughly 2 inches between them to give room for spreading.
Step 4: Press the Signature Pattern
Take a fork and lightly press down on each dough ball, creating that classic crisscross pattern peanut butter cookies are known for. This step is not only aesthetic but helps the cookies bake evenly.
Step 5: Bake and Cool
Bake for 10 to 12 minutes, watching for edges to set and turn a gentle golden brown. Once out of the oven, let the cookies cool on the baking sheet for about five minutes—this cooling period lets them firm up to the perfect chewy texture. Then transfer them to a wire rack to cool completely.
How to Serve Keto Peanut Butter Cookies Recipe

Garnishes
A light sprinkle of flaky sea salt on top just before baking can elevate these cookies by sharpening their sweet and nutty contrast. If you’re feeling extra indulgent, a drizzle of melted sugar-free chocolate adds a pretty, decadent touch and more complex flavor.
Side Dishes
These cookies pair beautifully with a cup of unsweetened almond milk or a rich bulletproof coffee for a satisfying snack or dessert break that keeps you in ketosis. You can also enjoy them alongside a small scoop of low-carb vanilla ice cream for a cool contrast.
Creative Ways to Present
Why not make a Keto Peanut Butter Cookie sandwich by slathering a bit of sugar-free cream cheese or whipped coconut cream between two cookies? This turns your cookie into a delightful mini treat perfect for parties or just spoiling yourself.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cookies fresh by storing them in an airtight container at room temperature for up to five days. The cookies maintain their chew nicely and can be enjoyed anytime without losing flavor or texture.
Freezing
If you want to prep ahead or make a big batch, these cookies freeze wonderfully. Place them in a freezer-safe container or bag, separating layers with parchment paper to prevent sticking, and freeze for up to three months.
Reheating
To bring frozen or refrigerated cookies back to life, pop them in a 300°F oven for about 5 minutes or microwave briefly in 10-second bursts until warm. Be careful not to overheat as they can dry out quickly.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add a delightful texture boost with little peanut bits in every bite. Just ensure it’s natural and unsweetened like the creamy version for the best keto-friendly cookie.
Is erythritol the only sweetener I can use?
Nope! You can substitute erythritol with your preferred keto-friendly sweetener such as monk fruit sweetener or allulose. Just keep the sweetness level similar to maintain the cookie’s balance.
Can I make these cookies nut-free?
Since peanut butter is the star here, swapping it out will change the recipe significantly. However, sunflower seed butter might be a viable alternative for a nut-free but similar flavor profile.
How can I make the cookies chewier?
Underbaking by a minute or two gives a softer, chewier texture. Also, using a slightly fresh egg and not overbaking are key tricks to keep them tender.
Are these cookies suitable for diabetics?
Because they are low-carb and use keto-friendly sweeteners that do not spike blood sugar, these cookies can be a good option for many diabetics. Nonetheless, always consult with a healthcare provider about your specific dietary needs.
