Step‑by‑Step Instructions for Easy Keto Peanut Butter Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, line a baking sheet with parchment paper or a silicone mat. This not only helps prevent the cookies from sticking but also ensures even cooking. The enticing aroma of warm cookies will soon fill your kitchen!
Step 2: Mix the Ingredients
In a large mixing bowl, combine 1.5 cups of natural peanut butter, 2 eggs, and 1/4 cup of erythritol or monk fruit sweetener. Using a spoon or spatula, stir the mixture until a smooth dough forms and all ingredients are fully incorporated. The dough should be thick and slightly sticky, embodying the essence of these Keto Peanut Butter Cookies.
Step 3: Form the Cookie Balls
With your hands, roll the dough into balls, about 1 tablespoon each, and place them onto the prepared baking sheet. Make sure to leave enough space between each ball, as they will spread out while baking. You’ll be creating perfectly portioned treats that are sure to be a hit!
Step 4: Flatten the Cookies
Take a wet fork and gently press each cookie down, flattening them to about 1/2 inch thick. This step not only helps shape the cookies but also creates a lovely criss-cross pattern on top. This visual cue adds a classic touch to your Keto Peanut Butter Cookies, making them as delightful to look at as they are to eat.
Step 5: Bake to Perfection
Place the baking sheet in the preheated oven and bake for 13 minutes. Keep a close eye on them; they should look slightly soft in the center when you remove them. If you prefer a firmer texture, bake for an additional 1-2 minutes, knowing they will firm up as they cool.
Step 6: Cool and Enjoy
After baking, allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. This cooling step is crucial, as it helps them set and enhances their chewy texture. Patience is key here—soon enough, you’ll have warm, delicious Keto Peanut Butter Cookies ready for indulgence!

Make Ahead Options
These Easy Keto Peanut Butter Cookies are perfect for meal prep, allowing you to enjoy them whenever a sweet craving strikes! You can mix the dough and refrigerate it for up to 3 days in an airtight container, keeping the flavors fresh and ready for action. Alternatively, you can pre-form the cookie balls and freeze them for up to 3 months; just place them on a baking sheet to freeze individually before transferring to a freezer bag. When you’re ready to savor your cookies, simply bake them straight from the freezer for an extra minute or two. This ensures that your Keto Peanut Butter Cookies remain just as delicious and satisfying, perfect for those busy weeknights when you want a homemade treat without the extra effort!

Easy Keto Peanut Butter Cookies Recipe FAQs
What type of peanut butter should I use?
Absolutely! It’s best to choose natural peanut butter that contains only peanuts and salt. Avoid brands with added sugars or hydrogenated oils, as they compromise the keto nature of the cookies. If you have nut allergies, you can substitute it with almond butter or sunflower seed butter, both of which work wonderfully in this recipe!
How should I store the cookies?
For short-term storage, place your Keto Peanut Butter Cookies in an airtight container at room temperature, where they will last for up to 1 week. If you prefer them chilled, they can also be stored in the fridge for up to 2 weeks. Always store them with some parchment paper in between layers to avoid sticking! For longer freshness, freeze them following the next tip.
Can I freeze the Keto Peanut Butter Cookies?
Yes, freezing is a great option! To freeze your cookies, first, place them in a single layer on a baking sheet and freeze until solid. Then, transfer the frozen cookies to a freezer bag or an airtight container, layering parchment paper between them if stacking. They can be kept frozen for up to 3 months. When you’re ready to enjoy them, just microwave for 10-15 seconds to regain that fresh-baked taste!
Why did my cookies spread too much while baking?
If your cookies spread excessively, it may be due to overly warm dough or not enough binding from the eggs. Ensure that your peanut butter was at room temperature and your dough isn’t too warm before baking. If the dough feels overly soft, you can chill it in the fridge for about 15-30 minutes before rolling and baking to help maintain their shape!
Are these cookies safe for people with nut allergies?
These Keto Peanut Butter Cookies are not suitable for individuals with nut allergies since they contain peanut butter. However, using alternatives like sunflower seed butter can provide a similar texture and flavor without the nuts, making them allergy-friendly! Just be sure to verify all ingredients and potential cross-contamination.
Can I add ingredients to cater to dietary needs?
Very! You can customize your cookies by adding sugar-free chocolate chips or chopped nuts if dietary permits. If you need a vegan option, substitute the eggs with flax eggs (1 tbsp flaxseed meal + 2.5 tbsp water per egg, let it sit until thick) for a delightful result! This flexibility allows you to adjust the recipe according to personal preferences and dietary constraints.
