Instructions

Step 1: Prepare Your Baking Environment

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat. This prevents sticking and ensures even baking.

Step 2: Mix the Dough

  1. In a medium mixing bowl, combine the peanut butter, erythritol, and egg. If you’re adding vanilla extract or other optional ingredients, mix them in now.
  2. Use a spatula or wooden spoon to mix the ingredients until a smooth dough forms. The consistency should be thick and slightly sticky.

Step 3: Portion the Dough

  1. Use a cookie scoop or tablespoon to divide the dough into 12 equal portions. Roll each portion into a ball with your hands.

Step 4: Arrange and Flatten

  1. Place the dough balls onto the prepared baking sheet, spacing them about 2 inches apart to allow for slight spreading.
  2. Using a fork, press down on each ball to create a crisscross pattern. This helps flatten the cookies for even baking and gives them a classic peanut butter cookie look.

Step 5: Bake the Cookies

  1. Place the baking sheet in the preheated oven and bake for 10–12 minutes. The cookies will be slightly soft in the center but will firm up as they cool.
  2. Keep an eye on them to prevent overbaking, as keto-friendly sweeteners can brown quickly.

Step 6: Cool Completely

  1. Remove the cookies from the oven and let them rest on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This step is essential for the cookies to firm up properly.

Tips for Success

  1. Choose the Right Peanut Butter: Use natural peanut butter with no added sugar or oils. Stir well before measuring to incorporate the natural oils.
  2. Sweetener Choice: Erythritol or monk fruit sweetener works best for this recipe as they don’t leave a bitter aftertaste. Adjust sweetness to your preference.
  3. Don’t Overbake: These cookies may look underdone when you first take them out, but they will firm up as they cool. Overbaking can make them dry.
  4. Storage: Store cookies in an airtight container at room temperature for up to 5 days, or freeze them for up to 3 months.

Why These Cookies Are Perfect for Keto and Weight Watchers

  1. Low in Carbs: With only 2 grams of net carbs per cookie, they fit perfectly into a keto diet.
  2. High in Healthy Fats: Peanut butter provides a good dose of healthy fats, keeping you full longer.
  3. Low SmartPoints: Carefully measured ingredients result in only 2 WW SmartPoints per cookie (on all plans).

Customization Ideas

  1. Add Crunch: Use crunchy peanut butter or sprinkle chopped nuts on top before baking.
  2. Chocolate-Lovers: Stir in sugar-free chocolate chips or drizzle melted sugar-free chocolate over the cooled cookies.
  3. Holiday Twist: Add a pinch of cinnamon or nutmeg for a festive flavor profile.
