3 Ingredient Keto Peanut Butter Cookies

Yield: 12
Prep time: 10 MinCook time: 10 MinTotal time: 20 Min
Low-carb peanut butter cookies with a sugar-free peanut butter cup in the center for anyone watching their carbs. A healthier cookie that's easy and has only 3 ingredients!
Ingredients
- 1 cup sugar-free creamy peanut butter
- 1/2 cup brown sugar substitute (any brand of sugar-free brown sugar you prefer, our preference is swerve brand)
- 1 large egg
Instructions
- Preheat the oven to 350 degrees and prepare a baking sheet with parchment paper.
- In a microwave-proof bowl add the peanut butter with sugar substitute and hit for around 25 seconds.
- Mix to combine them both.
- Using a fork beat in the egg and it because a dough formed.
- Roll into balls and add to cookies.
- Gently pat dough to form a pattie shape and add fork tines on top.
- Bake for around 10 to 12 minutes.
- Don't overbake I usually test one on a pie plate first (every oven seems a little different).
- Cool then remove from the baking sheet.
- The cookies crumble easily as they are very fragile, but taste great.
- Optional: sugar-free peanut butter mini cups (we usually do that but these are optional) place one on each cookie when they come out of the oven in the center.
