Ingredients Notes

Peanut butter: I used a reduced sugar, creamy peanut butter. This gluten free peanut butter cookie recipe works best with a thicker peanut butter. I do not recommend using a natural peanut butter. (Try these Peanut Butter No Bake Cookies)
Sweetener: For this keto peanut butter cookie, I used a mix of monkfruit and erythritol for the sweetener. This is the brand I use. You can use any low carb sweetener that you prefer.
Egg: If you have an egg allergy and you need egg free peanut butter cookies, you can substitute the egg with a chia egg, a flax egg, or use this egg replacer.
Vanilla extract: To make these flourless keto peanut butter cookies, I recommend using pure vanilla extract instead of imitation vanilla extract. You could also use caramel extract or almond extract.

Step by Step Instructions

STEP 1: Preheat the oven to 350°F. Line a cookie sheet with a silicone baking mat or parchment paper. Place all of the ingredients in a large mixing bowl. Using a hand mixer, mix until the ingredients are well incorporated and form a thick dough.

STEP 2: Shape the dough into 1 ½ to 2 inch balls (12 total). Place the dough balls on the cookie sheet, about 2 inches apart.

STEP 3: Use a fork to flatten the cookies and make crisscross marks on top. Bake for 10 minutes, or until the edges are firm but the centers are still soft.

STEP 4: Remove the baking sheet from the oven and place it on a cooling rack. Allow the cookies to cool on the pan before eating.

My kids loved these, which is a win because they aren’t doing low carb like me. I enjoyed mine with a few Lilly’s chocolate chips and a bit of cream without the guilt! Will be making plenty more of these!
