What is Keto?

“Keto” refers to the ketogenic diet, which is a low carb lifestyle similar to Atkins. Essentially, one would limit the amount of carbs eaten in a day to kick the body into ketosis, where fat is burned for fuel.

Is Peanut Butter Keto?

This is one of the number one questions I get about this recipe…is peanut butter really keto??

The good news is that YES, in most cases, peanut butter is totally cool on a low carb or keto diet, in moderation of course.

As with any dessert, it’s a treat! If you eat one or two cookies, those carbs should easily fit into your daily allowance. The whole batch of cookies? Not so much.

How Many Carbs Per Cookie?

Based on our nutrition calculations, each cookie has 6g total carbs, or 2g net carbs. Generally, net carbs is what is used for figuring out how many carbs in a day for keto.

To find net carbs, take the total carbs per serving and subtract fiber per serving and sugar alcohol (if any) per serving.

How to Make Keto Peanut Butter Cookies

Preheat oven to 350°F and prep your baking sheet with a non-stick silicone baking mat or parchment paper.

Combine peanut butter, eggs, and sugar in a non-slip mixing bowl. Stir together until a smooth dough forms. You can stir with a wooden spoon or use an electric hand mixer to make the process a little easier.

Roll into balls (about 1 Tablespoon each) and place on your prepped baking sheet.

TIP: We love these non-stick silicone baking mats because they’re washable and nothing sticks to them – we use them for almost all of our baking projects!

Using a fork, press cookies down so they are about 1/2″ thick, making a criss-cross pattern.

TIP: Wet fork before pressing so that the fork doesn’t stick to the dough. We keep a small dish of water at our work area so it’s ready between each press.

How Long to Bake

All cooking times use an oven temperature of 350°F.

• For a chewy cookie: Bake for 12-13 minutes
• For a shortbread-like texture: Bake 14-15 minutes

Can You Use Stevia Instead?

Our original recipe actually did use Stevia. However, we were never 100% satisfied with the flavor, as stevia can sometimes leave a bit of an aftertaste.

After a bit of experimentation, we found that using monk fruit (Lakanto) or erythritol (Swerve) had a much better texture and flavor, in our opinion.

If you prefer stevia, you’ll want to use 2-4 teaspoons, as opposed to the 1/4 cup of other sweeteners. Other than the measurement difference for sweetener, the recipe is prepared exactly the same.
