If you’re on a keto diet or simply looking to reduce your carb intake without sacrificing delicious desserts, Keto Peanut Butter Cookies are an absolute game-changer. These cookies capture all the rich, nutty flavor of classic peanut butter treats, but with a low-carb, keto-friendly twist. Made with wholesome ingredients and free from grains and sugars, they’re perfect for satisfying your sweet tooth while keeping your macros in check.
In this article, we’ll dive into why Keto Peanut Butter Cookies are the ultimate guilt-free indulgence, share a detailed recipe, and offer tips for making the perfect batch every time.
Why Choose Keto Peanut Butter Cookies?
Traditional peanut butter cookies often rely on flour and sugar, both of which are off-limits or limited on keto and low-carb diets. Keto Peanut Butter Cookies swap these out for keto-friendly alternatives, offering several benefits:
- Low Carb & Sugar-Free: These cookies use natural sweeteners like erythritol or stevia, which don’t spike blood sugar or insulin levels. Almond or coconut flour replaces traditional wheat flour, keeping carbs minimal.
- High in Healthy Fats: Peanut butter is naturally rich in healthy fats, which help keep you full and support ketosis—a metabolic state where your body burns fat for fuel.
- Gluten-Free & Grain-Free: Ideal for those with gluten sensitivities or anyone avoiding grains.
- Simple Ingredients & Quick to Make: With just a handful of pantry staples, you can whip up these cookies in under 30 minutes, making them perfect for busy days or last-minute cravings.
- Delicious & Satisfying: Despite being keto-friendly, these cookies don’t compromise on taste or texture. They come out soft, chewy, and packed with peanut butter goodness.

Ingredients You’ll Need
Here’s what you’ll need to bake your own Keto Peanut Butter Cookies:
- Natural peanut butter (no added sugar or oils)
- Almond flour (or coconut flour for a different texture)
- Granulated erythritol or your preferred keto-friendly sweetener
- Egg (to bind the dough)
- Baking powder (to help the cookies rise slightly)
- Vanilla extract (optional, for flavor depth)
- Salt (a pinch to balance sweetness)
Step-by-Step Keto Peanut Butter Cookies Recipe
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
Step 2: Mix Wet Ingredients
In a mixing bowl, combine the peanut butter, egg, and vanilla extract (if using). Stir until smooth and creamy.
Step 3: Add Dry Ingredients
Add almond flour, erythritol, baking powder, and a pinch of salt to the wet mixture. Stir thoroughly until a thick cookie dough forms. The dough should be easy to shape but not too sticky.
Step 4: Shape the Cookies
Using a tablespoon or cookie scoop, form dough balls and place them on the prepared baking sheet. Flatten each ball gently with a fork, creating a classic crisscross pattern on top.
Step 5: Bake
Bake for 10-12 minutes or until the edges are golden and the cookies are set. Avoid overbaking to keep them soft and chewy.
Step 6: Cool and Enjoy
Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. This helps them firm up and achieve the perfect texture.
Tips for Perfect Keto Peanut Butter Cookies
- Choose the Right Peanut Butter: Use natural peanut butter with no added sugars or hydrogenated oils for the best flavor and health benefits.
- Adjust Sweetness: Taste your dough before baking and add a little more sweetener if you prefer a sweeter cookie.
- Add Mix-Ins: For extra flair, toss in sugar-free chocolate chips, chopped nuts, or shredded unsweetened coconut.
- Store Properly: Keep cookies in an airtight container at room temperature for up to 5 days or freeze for longer storage.
Variations to Try
- Chocolate Swirl Keto Peanut Butter Cookies: Add melted sugar-free chocolate swirled on top before baking.
- Keto Peanut Butter & Jelly Cookies: Spread a thin layer of sugar-free jam on half the cookies and sandwich them together for a nostalgic treat.
- Crunchy or Chewy: For crunchier cookies, bake a minute or two longer; for softer cookies, reduce baking time slightly.
