4-Ingredient Peanut Butter Cookies
This recipe makes a large batch (about 30 cookies.) Halve the recipe if you only want 15. You probably have everything you need to make these without a trip to the store:
- peanut butter: a smooth, natural variety. I used the Kirkland brand from Costco.
- eggs: large
- 0-calorie sweetener: like Swerve, Lacanto Monkfruit with Erythritol (or granulated sugar or coconut palm sugar if you’re not on a Keto diet.)
- pure vanilla extract
How to Make 4-Ingredient Peanut Butter Cookies
First mix all ingredients in a bowl, either by hand or with an electric mixer. Stir in add-ins, like chocolate chips or crushed peanuts, if you’d like.
Using a cookie scoop or your hands, form into balls and place on baking sheets lined with parchment paper or silicone baking mats.
Use a fork to flatten the balls, creating a cross-hatch pattern. Bake for 12 – 15 minutes at 350° F.
Remove and let cool for 5 minutes on the baking sheet before transferring to a cooling rack to cool completely. Cookies will harden slightly as they cool.
Variations
- Add 1/2 cup chocolate chips (use a Stevia-sweetened brand like Lily’s for Keto diet)
- Add 1/2 finely chopped peanuts or walnuts.
- Sprinkle with Himalayan sea salt just before baking.

Easiest 4-Ingredient Peanut Butter Cookies
Ingredients
- 2 cups natural peanut butter stirred to incorporate the oil
- 2 large eggs
- 1 cup zero-calorie sweetener like Monkfruit with Erythritol or Swerve
- 2 tsp pure vanilla extract
Instructions
- Preheat oven to 350° F. Line 2 baking sheets with parchment paper or silicone baking mats.
- In a large bowl, combine all ingredients with a spoon or an electric mixer. Stir until well blended.
- Use a cookie scoop to form balls about 1 inch in diameter, or roll in your hands. Transfer the balls to the prepared baking sheets and space them apart evenly.
- Use a fork to flatten the balls, creating a cross-hatch pattern.
- Bake for 12 - 15 minutes or until cookies are golden brown. Remove from oven and let sit on the cookie sheet for 5 minutes or so. If you move them too soon, they will be too soft and will crumble. Once firm, transfer to a cooling rack to cool completely. Cookies will firm up as they cool.
