Easy Keto Peanut Butter Cookies Recipe (Low Carb)

The secret to staying on your keto diet is having recipes ready to use when your sweet tooth hits. Those cravings are hard to ignore and you don’t want to derail your hard efforts. I practice a keto diet alongside Intermittent Fasting and I’ve seen great results.

Each week I meal prep and make a few of my favorite recipes ahead of time, so I won’t be tempted to grab junk. That includes something sweet too!

Peanut Butter Cookies are a favorite when I’m not on my keto diet, so why not have an alternative that I can still enjoy? These cookies are easy to make and really satisfy my sweet tooth. 

Basically, you make the dough and press the cookies down with a fork to get that signature peanut butter cookie look that everyone loves. My kids will even help me make these cookies because they’re just fun and easy to throw together.

The best part? My Husband adores the taste of these Keto Peanut Butter Cookies. He doesn’t follow a ketogenic diet and I had to tell him that these are low carb cookies. He would’ve never known! They just taste that good.

How Long Do Keto Peanut Butter Cookies Last?

This recipe will make 1 dozen cookies. I eat 1-2 cookies per sitting and they’ll last me about a week or two. The key is to store your cookies in an air-tight container. You don’t have to refrigerate your cookies. They can sit out.

How Many Net Carbs Are In Each Cookie?

Each cookie has 2g of net carbs. You want to find a low sugar peanut butter. Skippy and Jif peanut butter brands work too, but that won’t give you the low net carbs. As a sugar substitute, I use the granular Swerve sugar. You can purchase it off of Amazon. It has a six month shelf life.

Can I Freeze The Cookies Or The Cookie Batter?

Since this recipe is so easy to make, you won’t need to freeze the batter ahead of time. You literally just dump and stir into a dough. However, if you want to freeze the cookies after they’re baked, that’s totally doable! You can make a batch and freeze them for 3-4 months. I did a test batch.

After you freeze your Keto Peanut Butter Cookies, you can just let one thaw for 1-2 hours at room temperature before eating. If you like to eat one warm, just nuke in the microwave for about 10-15 seconds after thawing.
