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.

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!
