These Keto Peanut Butter Cookies are a quick and delicious low-carb treat perfect for those following a ketogenic lifestyle. Made with simple ingredients like peanut butter, powdered erythritol, and egg, these cookies are easy to prepare and only require about 20 minutes from start to finish. The cookies have a delightful chewy texture with a classic peanut butter flavor and are sweetened naturally with erythritol, making them sugar-free and keto-friendly.

Ingredients

Ingredients

  • 1/2 cup crunchy unsweetened peanut butter (preferably Costco brand)
  • 1/4 to 1/3 cup powdered erythritol or Swerve Confectioners
  • 1 large egg

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
  2. Mix Ingredients: In a mixing bowl, combine the peanut butter, powdered erythritol, and egg. Use a spatula to mix thoroughly until the mixture is uniform and well combined.
  3. Shape Cookies: Using a 1.5 tablespoon cookie scoop, portion out the dough and roll into balls. Place the balls evenly spaced on the prepared baking sheet. Press each ball gently with a fork to create a crisscross pattern on the top of each cookie.
  4. Bake: Place the baking sheet in the preheated oven and bake for 12–15 minutes or until the tops are set and lightly golden around the edges.
  5. Cool: Remove the cookies from the oven and let them cool on the baking sheet for about 10 minutes. This helps them firm up and improves the texture before serving.

Notes

  • For sweeter cookies, use 1/3 cup powdered erythritol; for less sweetness, stick to 1/4 cup.
  • Use crunchy peanut butter to add texture, or smooth peanut butter for a softer cookie.
  • Ensure the peanut butter is unsweetened and natural to keep the recipe keto-friendly.
  • Letting cookies cool completely helps them set and prevents crumbling.
  • Store cookies in an airtight container at room temperature for up to one week or refrigerate for longer freshness.
