Keto Peanut Butter Cookies
When I first discovered keto baking, I thought my cookie days were over. These keto peanut butter cookies completely changed that! I’ve perfected this recipe over months of testing, and I can honestly say they rival any traditional peanut butter cookie I’ve ever made.
What makes these cookies truly special is their incredible simplicity. With just six basic ingredients, you can whip up a batch in under 30 minutes. I’ve served these to non-keto friends who are always shocked when I tell them each cookie contains less than 1 net carb!
Why You’ll Love This Recipe
No compromises on taste or texture. These cookies are soft, chewy, and packed with rich peanut butter flavor. Unlike other keto cookies that often turn out dry and crumbly, these are perfectly moist and satisfying.
Incredibly versatile. While I use peanut butter below, I’ve successfully made these with almond butter, cashew butter, and even sunflower seed butter for nut allergies. Each variation brings its own delicious twist.
Guilt-free indulgence. Each cookie contains less than 1 net carb, making them perfect for ketogenic, low-carb, or diabetic-friendly eating plans. They’re naturally gluten-free and easily made vegan.
The Secret to Perfect Keto Cookies
After countless batches, I’ve discovered the key secrets:
Temperature matters. Always use room-temperature peanut butter for smooth mixing. If it’s too thick, warm it gently in the microwave for 10-15 seconds.
Don’t overbake. These cookies should look slightly underbaked when removed from the oven. They’ll firm up as they cool, creating that perfect chewy texture.
Quality ingredients make a difference. I use natural peanut butter without added sugars and super fine almond flour for the best texture. The powdered erythritol dissolves beautifully without any aftertaste.
Unlike traditional cookies requiring eggs and butter, this recipe strips down to essentials while delivering maximum flavor. The dough is safe to eat raw (no eggs!), so I always sneak a few spoonfuls while baking.
These cookies freeze beautifully and are perfect for meal prep. I keep a batch in my freezer because they thaw quickly and taste fresh. Whether you’re new to keto baking or experienced, this foolproof recipe will become your go-to dessert!

Why These Ingredients Work
Peanut butter provides both flavor and structure. I’ve tested various nut butters – almond butter creates nuttier flavor, cashew butter makes them extra creamy, and sunflower seed butter works for nut allergies.
Almond flour replaces wheat flour perfectly. I use finely ground almond flour for smoother texture. The natural oils keep cookies moist, which is often challenging in keto baking.
Powdered erythritol dissolves seamlessly, creating sweetness without carbs. I use powdered rather than granulated because it incorporates easily without gritty texture.
Step-by-Step Instructions
Preparation
Step 1: Preheat oven to 325°F (163°C). Line a baking sheet with parchment paper.
Step 2: Ensure peanut butter is room temperature and easily stirrable. Warm gently if needed.
Making the Dough
Step 3: In a medium bowl, whisk together almond flour, powdered erythritol, salt, and baking soda until well combined.
Step 4: Add peanut butter and milk. Stir until cohesive dough forms. If too dry, add extra teaspoon of milk. If too wet, add tablespoon more almond flour.
Pro tip: Taste the dough! It’s safe since there are no eggs. Add more salt if using unsalted peanut butter.
Shaping and Baking
Step 5: Roll dough into 8 walnut-sized balls. Place on baking sheet, spacing 2 inches apart.
Step 6: Using a fork, gently press crosshatch pattern on each cookie. Don’t flatten completely.
Step 7: Bake 12-15 minutes until set around edges but still soft in center. Don’t let them brown.
Step 8: Cool on baking sheet for 10 minutes before transferring. They’ll firm up during cooling.
Storage Tips
Store in airtight plastic container for soft cookies or glass container for crispier texture. They stay fresh up to one week at room temperature. For longer storage, freeze individually wrapped for up to 3 months – they thaw quickly and taste fresh-baked!
Variations, Tips & FAQ
Troubleshooting Common Issues
Cookies spreading too much: Peanut butter is too warm or dough too wet. Use room-temperature (not hot) peanut butter and avoid extra milk unless necessary.
Cookies too crumbly: Not enough moisture. Add extra teaspoon of milk or use creamier peanut butter brand.
Cookies too hard: Overbaked. Remove when edges are set but centers still look soft – they continue cooking on the hot pan.
Delicious Variations
Chocolate Chip: Fold in 2 tablespoons sugar-free mini chocolate chips after forming dough. Lily’s brand works perfectly.
Almond Butter Cookies: Replace peanut butter with equal amount almond butter for more delicate, sophisticated flavor.
Cinnamon Spice: Add 1/2 teaspoon ground cinnamon and pinch of nutmeg to dry ingredients for fall-inspired cookies.
Double Peanut Butter: Stir in 2 tablespoons chopped sugar-free peanut butter chips for extra flavor and texture.
Make-Ahead Tips
Freezer dough balls: Roll into balls and freeze on baking sheet. Transfer to freezer bag once frozen. Bake directly from frozen, adding 2-3 extra minutes.
Pre-mixed dry ingredients: Prepare several batches of dry mixture in mason jars. Just add wet ingredients when ready to bake.
Refrigerated dough: Prepared dough keeps 3 days in fridge, covered. Let come to room temperature before shaping.
Nutritional Benefits
Each cookie provides approximately 3g protein from peanut butter and almond flour, making them more satisfying than traditional cookies. Healthy fats help stabilize blood sugar, preventing energy crashes. Almond flour contributes vitamin E, magnesium, and fiber. At less than 1 net carb per cookie, they fit perfectly into low-carb lifestyles.
Frequently Asked Questions
Can I substitute almond flour with other flours? Other nut flours like pecan or hazelnut work with same measurements. Coconut flour requires major adjustments (use only 1/4 cup) because it absorbs much more liquid. Add liquid gradually if experimenting with coconut flour.
What if I don’t have powdered erythritol? Grind granulated erythritol in food processor until powdery. Powdered monk fruit sweetener works with same measurements. Regular powdered sugar is fine if not following keto.
Can these be made vegan? Yes! Use plant-based milk like almond or coconut milk. Ensure peanut butter doesn’t contain honey for fully vegan cookies.
How do I know when they’re perfectly baked? Cookies should be set around edges but still look slightly soft in center when removed. They should NOT be golden brown. They firm up considerably while cooling.
Can I scale this recipe? Absolutely! Recipe doubles or triples beautifully. Just ensure adequate baking sheet space or bake in multiple batches to avoid overcrowding.
These keto peanut butter cookies have become a household staple, bringing joy without compromising health goals. The perfect combination of simplicity, incredible taste, and keto-friendly ingredients makes them ideal for any occasion!
