How to Make Keto Peanut Butter Cookies
Step 1: Prep the Dough
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. In a medium bowl, mix together peanut butter, powdered erythritol, egg, and vanilla extract until smooth and well combined.

Step 2: Shape the Cookies
Using a small cookie scoop or a tablespoon, portion out 1-inch balls of dough and arrange them on the prepared baking sheet, leaving about 2 inches between each.
Step 3: Classic Crosshatch
Flatten each cookie gently with a fork, making a crisscross pattern for that classic peanut butter cookie look.
Step 4: Bake and Cool
Bake in the preheated oven for 10-12 minutes, or until the edges are set and the tops are lightly golden. Let the Keto Peanut Butter Cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
