Here is how you can make low-carb peanut butter cookies in your style:
Nut-Free Option
Love sugar-free peanut butter cookies but can’t tolerate tree nuts?
Cashew flour can be used instead of almond flour, and sunflower seed butter instead of peanut butter. So the cookies are perfect for anyone on a keto or diabetic diet, even though they are nut-free. The taste is equally good, and the cookies stay tender and chewy.
Vegan Variation
Looking for butterless peanut butter cookies that are also egg-free?
Replace the egg with the same amount of a chia egg or flax egg (a mixture of a tablespoon of ground flax or chia with three tablespoons of water). These key ingredients help the dough stick together which leads to a tasty keto and plant-based cookie.
You can also try these peanut butter cookies without baking soda, just use almond flour; the egg substitute and the texture of the almond flour will support the structure instead.
Chocolate Lovers
Turn this into a low-carb chocolate peanut butter cookie by adding a handful of sugar-free chocolate chips. This is a game-changer for anyone craving keto cookies peanut butter and chocolate style. You can even melt extra chips on top for a gooey finish!
Crunchy Peanut Version
If you don’t like soft cookies, add some crushed roasted peanuts for the classic crunch. So, they taste similar to the classic diabetic peanut butter cookies, but without the excess sugar or carbs.
Low FODMAP Friendly
Need a low-calorie peanut butter cookie that won’t upset your gut?
Use peanut butter made from blanched peanuts (no skins), and skip erythritol, which can trigger digestive issues. Instead, sweeten with allulose—a FODMAP-safe, diabetic-friendly sugar substitute that still delivers a sweet taste without raising blood sugar.

If you are wondering: Why are my 6-ingredient peanut butter cookies falling apart?
Wait for them to completely cool down before taking them off the baking sheet. Due to keto ingredients, these cookies crumble easily, that why it is best to let them cool down before touching them.
Another interesting substitute ingredient for these peanut butter cookies are bananas. That’s right! You can use bananas instead of eggs for this recipe and it turns just so well. It gives this extra rich and delicious flavour to the cookies.
What ingredient can replace peanut butter?
There are a lot of other options that you can try instead of peanut butter, such as tree nut butters, such as almond, walnut, cashew, pecan butters, and hazelnut. But then you can’t call these cookies Keto Peanut Butter Cookies, naturally.
