    This recipe for the easiest 4-Ingredient Peanut Butter Cookies is almost unbelievable. I had my doubts that I could make peanut butter cookies without either flour OR sugar. You'll be surprised at how easy they are to make and how good they taste!

    I like to make these sugar-free peanut butter cookies for my grandkids who can't have peanut butter in their school lunches when their classmates have a peanut allergy. They understand how serious a peanut butter allergy can be, but they love to devour these cookies when they visit me.

    🛒 4 simple ingredients for the easiest 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 like using creamy peanut butter in this recipe, but you can use crunchy peanut butter if you'd like. I use the Kirkland brand from Costco.
    • eggs: you'll need 2 large eggs at room temperature.
    • sweetener:  to keep it keto, use a 0-calorie sweetener like Lacanto Monkfruit with Erythritol (or granulated sugar, brown sugar, or coconut palm sugar if you're not on a Keto diet.)
    • pure vanilla extract

    🥄 How to make peanut butter cookies without flour

    First mix all ingredients in a bowl. This recipe doesn't need a stand mixer, but if you have one, it makes the cookie dough very easy to mix.

    Stir in add-ins, like chocolate chips or crushed peanuts, if you'd like.

    Mixing cookie dough with a spoon

    Using a small cookie scoop or your hands, form cookie dough balls and place them on prepared baking sheets lined with parchment paper or silicone baking mats.

    Using a cookie scoop to put cookies on a baking sheet

    Use the tines of a fork to flatten the balls, creating a criss-cross or cross-hatch pattern.

    Bake for 12 - 15 minutes at 350° F.

    Remove the cookie sheet from the oven and let the cookies cool for 5 minutes before transferring them to a wire rack to cool completely. These homemade peanut butter cookies will harden slightly as they cool.

    🔁 Variations

    This recipe is so versatile!

    • Add ½ cup chocolate chips (use a Stevia-sweetened brand like Lily's for Keto diet)
    • Add ½ finely chopped peanuts or walnuts.
    • Sprinkle with Himalayan sea salt just before baking.

    If you love cookies as much as I do, try these Keto Almond Butter Chocolate Chip Cookies.

    🥶 Storing and freezing your flourless peanut butter cookies

    These cookies can be stored in an airtight container on the counter for up to 5 days. They freeze well, too! Stack in an airtight container and freeze for up to 3 months.

    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 (or granulated sugar or coconut sugar if not on a keto diet)
    • 2 teaspoon 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 the tines of 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.

    Notes

    Add ½ cup chocolate chips or finely chopped nuts to the batter before rolling, if you'd like.

      You're right. These are super easy and really good. I'm going to make them with almond butter next time, just for a change.

        Great idea. I've done that too (and added extra chopped almonds.) They're delicious!
