2 Ingredient Keto Peanut Butter Cookies (No Special Flours or Sugar)

These keto peanut butter cookies are made with just 2 ingredients. Plus, you don’t need any special low-carb flour or sweeteners.  The dough takes only five minutes to prepare, and you don’t even need an electric mixer.

If you’re looking for a low-carb keto treat that doesn’t use any sugar (like erythritol) or flour alternatives, these cookies are for you. They taste good even though they are completely sugar-free peanut butter cookies. They have a pure peanut butter flavor and are crunchy and crumbly, like biscuit cookies.


  • Peanut Butter
  • Egg

Peanut Butter: I made these with natural peanut butter. This is the kind of peanut butter you need to stir before using, and has only peanuts and salt in the ingredient list. You can use unsalted peanut butter, but I think the salt gives these cookies flavor. Peanut butter can be substituted with almond butter.

Egg: This is the binder that holds the cookies together. I have not tested this recipe with other egg substitutes.

How to Make Them

This recipe makes 12 cookies, and the cookie dough is so easy to make. It takes less than five minutes to prepare.

Just mix the peanut butter and egg until a cookie dough forms. Scoop onto a baking sheet and bake!

Cookie Texture and Taste

These cookies have a crunchy, crumbly texture. Because they are made with so few ingredients, they do fall apart more easily than your typical cookie. But they still taste great.

They are similar to biscuit cookies, except that they crumble more easily.

These cookies do not contain any sweetener, so do not expect them to taste sweet. These cookies might not be for you if you are expecting something sweet. If you prefer sweet peanut butter cookies, I do have a recipe for sweeter low carb peanut butter cookies.

These cookies taste savory. I don’t always enjoy savory cookies, but I think it works when using peanut butter because peanut butter has such a strong flavor and can be enjoyed without adding sweetness.

  • 3/4 cup (192 g) natural unsweetened peanut butter
  • 1 large egg


  • Preheat oven to 350°F (177°C). Line a large baking sheet with parchment paper.
  • Add peanut butter and egg to a large mixing bowl. Mix until egg is fully incorporated, no egg white streaks remain and the mixture forms a thick dough.
  • Use a 1.5 tbsp cookie scoop to scoop out dough and place onto the prepared baking sheet. Use the back of a fork to make criss-cross pattern onto the surface of each dough ball. Each cookie should be a thick round disk after making the criss-cross pattern. If it's not, you can use your fingers to shape the edges as needed. Place cookies into the oven and bake for about 12 minutes.
  • Let cookies cool on cookie sheet. Do not attempt to remove them before they are cooled because they will break. Once cookies are cooled you should be able to remove them from baking sheet. Cookies do break easily so be gentle when transferring them.


  • These cookies are not sweet. They are savory peanut butter cookies. They have a texture similar to biscuit cookies though they are more crumbly because they are made of so few ingredients. See post for more details on taste and texture.
