Peanut Butter Cookie Ingredients
You’ll only need 3 simple ingredients for these delicious peanut butter cookies!

- Peanut butter – natural unsalted peanut butter that has no added sugars. Check the nutritional information carefully because lots of store-bought peanut butter have added sugar.
- Erythritol – to help add sweetness to the cookies, we’ll use Erythritol. Feel free to substitute with any of your preferred sugar-free sweeteners.
- Egg – one large, preferably free-range egg at room temperature to help bind everything together.
How To Make Keto Peanut Butter Cookies
- Preheat your oven to 350 degrees Fahrenheit (180 degrees Celsius) and line a baking tray with baking paper.

In a mixing bowl, combine the peanut butter, egg, and Erythritol.

Use a spatula (or your hands!) to mix the ingredients together thoroughly until they form a cookie dough.

Shape the dough into balls in the palms of your hands. I made 15 cookies with this recipe, and I feel they were a perfect size.

Transfer the balls onto the lined baking tray leaving space in between each ball.

- Decorate the cookies. Press down on the balls with the back of a fork. You can also use the back of your hand or experiment with various other shapes for different patterns!
- Bake the keto peanut butter cookies for 10 minutes until golden brown..
