Keto Peanut Butter Cookies

Low-carb, flourless peanut butter cookies sweetened with a sugar-free alternative—perfect for a keto-friendly treat.

Ingredients

Units Scale
  • 1 cup natural peanut butter (no sugar added)
  • 1/2 cup erythritol or monk fruit sweetener
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking powder
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a bowl, combine peanut butter, sweetener, egg, vanilla, baking powder, and salt. Mix until smooth.
  3. Roll dough into 1‑inch balls and place on the prepared sheet.
  4. Flatten each ball with a fork, making a crisscross pattern.
  5. Bake 10–12 minutes until edges are lightly golden. Centers may seem soft but will firm up.
  6. Let cool on baking sheet for 5 minutes before transferring to wire rack.

Notes

  • Use crunchy peanut butter for texture.
  • Substitute almond butter to reduce peanuts.
  • Add 1/4 cup sugar‑free chocolate chips or chopped nuts if desired.
  • Store cooled cookies in an airtight container at room temperature up to 5 days, or freeze for longer shelf life.
