Description

These 3-Ingredient Peanut Butter Cookies are a quick and simple treat perfect for any occasion. Made with just peanut butter, egg, and brown sugar (or a keto-friendly sugar substitute), these cookies are deliciously soft with a classic fork-pressed pattern, baked to golden perfection in just 8 minutes.


Ingredients

Units Scale

Standard Ingredients

  • 1 cup creamy peanut butter
  • 1 large egg
  • 1/2 cup firmly packed brown sugar

Keto / Sugar-Free / Low Carb Ingredients

  • 1 cup creamy peanut butter (just peanuts or peanuts and salt - lowest net carb count)
  • 1 large egg
  • 1/2 cup brown sugar alternative (Purecane Sugar Substitute Brown Sweetener recommended)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it is hot and ready when your cookie dough is prepared.
  2. Mix Ingredients: In a large mixing bowl, combine the peanut butter, egg, and brown sugar (or sugar substitute for keto). Whisk thoroughly until the mixture is smooth and fully incorporated.
  3. Shape Dough: Scoop tablespoon-sized portions of the dough and roll each into balls with your hands to ensure even sizing.
  4. Arrange on Baking Sheet: Place the dough balls on a parchment-lined baking sheet, spacing them about 2 inches apart to allow for spread during baking.
  5. Flatten & Pattern: Using the back of a fork, press down each dough ball to flatten slightly and create a characteristic cross-hatch pattern on top of each cookie.
  6. Bake Cookies: Bake the cookies in the preheated oven for 8 minutes until they are set and lightly golden around the edges.
  7. Cool: Remove the baking sheet from the oven and transfer the cookies to a wire rack to cool completely before storing or serving.

Notes

  • The nutritional values provided in the recipe card account for the entire batch, including both standard and keto variations.
  • For a firmer dough, firmly pack the brown sugar when measuring, or adjust the amount to ¾ to 1 cup depending on the moisture of your peanut butter.
  • If the dough is too soft, try chilling the peanut butter before mixing or using granulated sugar instead of brown sugar to thicken the dough.
  • Using large eggs is important for the correct dough consistency; medium eggs may result in a softer dough.
