Low Carb Keto Peanut Butter Cookies

These low carb keto peanut butter cookies combine crunchy peanut butter, granulated sweetener, egg, sea salt, and optional cinnamon for a dense, slightly chewy cookie. The cookies are formed into small balls, flattened, and baked until their edges firm while maintaining a soft center. Once cooled, they develop a crisp texture, making them suitable as a keto-friendly treat that balances sweet and salty flavors.

Ingredients

  • 1 cup peanut butter 250g, crunchy, 100% peanuts
  • ½ cup granulated sweetener (100g)
  • 1 egg large
  • pinch of sea salt
  • cinnamon optional; ½ teaspoon

Instructions

    Cup of Yum
  1. Preheat oven to 180 Celsius / 350 Fahrenheit.
  2. Put all ingredients in a bowl and mix with a fork.
  3. Roll small balls of dough (about 15g each) with your hands (or use a small cookie scoop) and flatten them on a baking sheet.
  4. Wet a fork and press on cookies to create a criss cross pattern.
  5. Bake 8 -10 minutes, until the edges are firm. (8 minutes = soft centre, 10 minutes = overall crunchy)
  6. Let cool completely before eating. They are very soft when just out of the oven, but will become crunchy once cooled.
  7. Store in an airtight container.

Notes

  • Each cookie contains about 6 grams of net carbs, suitable for low carb diets.
  • Choose peanut butter that contains only peanuts without other ingredients for best results.
  • You can make your own peanut butter using a food processor if desired.
  • Incorporating sea salt into the dough and sprinkling some on top balances sweetness with a salted caramel effect.
  • Store cookies in an airtight container to keep them fresh.
