Ingredients

  • 1 cup natural unsweetened peanut butter (use natural almond butter for paleo / keto)
  • 1 large egg , room temperature
  • 1/2 cup granulated or golden monk fruit sweetener , plus more for sprinkling on the tops if desired (you can also use your preferred low carb sweetener)

Optional but HIGHLY recommended to bring out the flavor

  • 1 teaspoon vanilla extract
  • 1/8 teaspoon sea salt
  • 1/2 teaspoon ground cinnamon

Instructions

  1. Preheat oven to 350 degrees F. Line a baking sheet with parchment paper or a silicone mat.
  2. In a large bowl, beat together the peanut butter and monk fruit sweetener until smooth. Add the egg and mix until well combined. Add optional ingredients, as desired.

  3. Use a medium (1.5 tablespoon) cookie scoop to make about 14 cookies. If you like the crystallized crunch, sprinkle tops of cookies with additional granulated monk fruit sweetener.

    Place dough balls on prepared baking sheet at least 2 inches apart, and then use a fork to flatten and form a criss-cross pattern.

  4. Bake in preheated oven for 9 to 11 minutes, until the cookies are just slightly browned on the bottom. Be careful not to over-bake as the cookies will continue to cook. Allow to cool on the baking sheet for at least 20 minutes before transferring to a wire rack.
