How to Make Keto Peanut Butter Cookie
Now that you have your ingredients ready, let’s dive into the fun part—making these delicious Keto Peanut Butter Cookies! Follow these simple steps, and you’ll have a batch of cookies that will make your kitchen smell heavenly.
Step 1: Preheat the Oven
First things first, preheat your oven to 350 degrees Fahrenheit. This step is crucial because it ensures that your cookies bake evenly. If you skip this, your cookies might end up unevenly cooked, which can lead to a chewy or burnt disaster. Trust me, a well-preheated oven is the secret to perfect baking!
Step 2: Mix the Ingredients
In a large bowl, combine your all-natural peanut butter, large egg, and granulated Swerve. Use a sturdy spoon or spatula to mix everything together until it’s smooth and well-blended. If you find the mixture a bit thick, don’t worry! That’s normal for low-carb peanut butter cookies. Just make sure there are no lumps, as a smooth batter will yield the best results.
Step 3: Shape the Cookies
Now comes the fun part—shaping your cookies! Roll the dough into about 1-inch balls. This size is perfect for a bite-sized treat. Place them on a greased cookie sheet, leaving some space between each ball. Then, take a greased fork and gently press down on each ball to flatten it. This not only gives your cookies that classic look but also helps them bake evenly. Plus, it’s a great way to get the kids involved!
Step 4: Bake the Cookies
Pop your cookie sheet into the preheated oven and bake for 10-12 minutes. Keep an eye on them! They might not look fully baked when you take them out, but don’t be tempted to leave them in longer. They will firm up as they cool. Let them sit on the pan for about 5 minutes before transferring them to a wire rack. This cooling time is essential for achieving that perfect texture. Enjoy the aroma wafting through your kitchen—it’s pure bliss!

Tips for Success
- Use room temperature ingredients for better mixing.
- Don’t skip the cooling time; it’s key for the right texture.
- Experiment with different nut butters for unique flavors.
- For a sweeter cookie, add a bit more Swerve to taste.
- Store cookies in an airtight container to keep them fresh longer.
Equipment Needed
- Mixing Bowl: A large bowl for combining ingredients. A sturdy glass or ceramic bowl works well.
- Fork: For flattening the cookies. You can also use a potato masher if you prefer.
- Cookie Sheet: A baking sheet lined with parchment paper or greased for easy cleanup.
- Measuring Cups: Essential for accurate ingredient measurements, though you can eyeball it for simplicity.
Variations To Try
- Chocolate Chip Keto Peanut Butter Cookies: Add sugar-free chocolate chips to the dough for a delightful twist.
- Nut-Free Option: Substitute peanut butter with sunflower seed butter for a nut-free treat that’s just as delicious.
- Spiced Cookies: Mix in a teaspoon of cinnamon or a pinch of nutmeg for a warm, cozy flavor.
- Protein Boost: Add a scoop of your favorite low-carb protein powder to the mix for an extra nutritional punch.
- Fruity Delight: Incorporate a few crushed raspberries or blueberries for a fruity flavor that pairs beautifully with peanut butter.
Serving Suggestions
- Pair your Keto Peanut Butter Cookies with a glass of unsweetened almond milk for a delightful treat.
- Serve alongside fresh berries for a refreshing contrast to the rich peanut butter flavor.
- For a fun presentation, stack cookies on a decorative plate and sprinkle with a dusting of cocoa powder.
