This keto peanut butter cookie is soft and has a robust peanut butter flavor. The best part is, it is super easy to make, and it makes exactly one serving. All you need are six ingredients and a microwave! The ingredients include almond flour, peanut butter, coconut flour, monk fruit blend sweetener, softened butter, and salt. You may have also noticed what is not on this list – egg! This recipe is an egg-free, vegan-friendly (if you use vegan butter) recipe for a delicious peanut butter cookie. The single-serving recipe is also perfect for portion control and allows you to enjoy desserts moderately.

There are lots of microwave cookie recipes out there, but many are mug cookies (really, it’s just a smaller mug cake, though). With this recipe, we don’t need egg so we don’t have to bake the cookie in a mug.

Benefits of Portion Control

Many keto diet recipes make large batches of cookies or desserts, making it difficult to prevent overeating, especially if you are the only one in your house that eats keto. With lots of leftover desserts, you can end up wasting ingredients, or even worse, eating just for the sake of finishing the leftovers. When you eat all of the desserts to prevent throwing them out, it can hinder weight loss and negate your keto diet.

That’s why I love portion controlled, single serve recipes. You can still enjoy a keto cookie without having to go overboard and halting all of your hard work. Check out my mini pumpkin pie recipe or chocolate mug cake recipe if you are looking for more keto desserts for one.

Is Peanut Butter Keto?

Although peanut butter is higher in carbs than the other kinds of nut butters, you can still eat peanut butter in small quantities while on a keto diet. Two tablespoons of peanut butter has 7g total carbs and 3g net carbs, and while the carb count is not exceptionally high, it is still important to portion control the amount of peanut butter cookies you eat.

You can also use other types of nut butter to make a keto cookie. For example, almond butter or macadamia nut butter has less net carbs than peanut butter. And if you don’t particularly love peanut butter or are craving a different taste, almond butter and macadamia nut butter are fun kinds of nut butter to try. Since this microwave cookie recipe quickly makes one cookie, you can even make a handful of cookies with different types of nut butter to decide which you and your family like the best.

A delicious addition is to add a keto peanut butter cup to the center of this cookie.

  1. I really enjoyed this recipe. I made one change. I added 2 Tsp Sukrin gold. This took care of my cookie craving. I’ve also tried your individual chocolate chip cookie recipe. Thanks a bunch!?

  2. I love this recipe, however, I’ve sadly concluded that I really need to avoid dairy. Can I sub coconut oil for the butter? Or is there enough oil in the pnb so as to not need to add extra? Thanks!

    1. I have actually made 3 ingredient peanut butter cookies in microwave a few weeks ago … 1 cup peanut butter, 1 large egg and 1/2 to 1 cup sugar. I’ve placed 12 balls (which I’ve then lightly pressed down with a fork) on a greased dinner plate. A bit brittle, but quick and yum. (My microwave is really ‘weak’ (700 watts), so use the above recipe’s microwave directions and see.
