Description

These Keto Peanut Butter Cookies are a quick and easy low-carb treat perfect for satisfying your sweet tooth while staying within your keto lifestyle. Made with natural peanut butter, erythritol, and a hint of vanilla, they bake up soft, chewy, and delicious with a classic criss-cross fork pattern on top.


Ingredients

Scale

Dry Ingredients

  • ½ cup granulated erythritol or monk fruit sweetener
  • ¼ teaspoon salt (optional, if peanut butter is unsalted)

Wet Ingredients

  • 1 cup natural peanut butter (no added sugar)
  • 1 large egg
  • 1 teaspoon vanilla extract


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent the cookies from sticking.
  2. Mix Ingredients: In a medium bowl, combine the natural peanut butter, granulated erythritol or monk fruit sweetener, large egg, vanilla extract, and salt (if using). Stir everything together until you form a smooth and consistent dough.
  3. Form Dough Balls: Using a tablespoon, scoop out portions of dough and roll each into a ball with your hands. Place these balls onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading during baking.
  4. Flatten and Create Pattern: Press down on each dough ball with a fork to flatten it slightly and create the classic criss-cross pattern on the top of each cookie.
  5. Bake Cookies: Bake the cookies in the preheated oven for 10 to 12 minutes, or until the edges are set but the center is still soft.
  6. Cool: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This helps them set properly and improves texture.

Notes

  • Use natural peanut butter with no added sugar to keep the recipe low carb and keto-friendly.
  • If your peanut butter is unsalted, adding ¼ teaspoon of salt enhances flavor, but it’s optional.
  • Store cookies in an airtight container at room temperature for up to 5 days or refrigerate for longer freshness.
  • Substitute erythritol with monk fruit sweetener for a different keto-approved sweetener option.
  • For a crunchier texture, bake an extra 1–2 minutes but be careful not to over-bake as they can become dry.
