Essential Ingredients

To create these delightful peanut butter cookies without sugar and carbs, you will need the following key ingredients:

  • Natural peanut butter: Choose a smooth, drippy variety with no added sugar.
  • Keto-friendly sweetener: Options include allulose, monk fruit, or erythritol. Feel free to pick your favorite.
  • Egg: Make sure to use a room temperature egg for optimal results.

How to Create Keto Peanut Butter Cookies

Step 1: Preparing the Dough

Combine the peanut butter, sweetener, and egg in a mixing bowl and stir until thoroughly mixed.

Step 2: Baking the Cookies

Using a 2-inch cookie scoop, arrange portions of the dough on a lined baking sheet. Bake the cookies in the oven for 10-12 minutes, or until the edges become firm. Allow the cookies to cool completely on the pan.

Tips to Make the Finest Grain-Free Recipe

To create the perfect grain-free treat, take care not to over-bake your cookies; they’ll still firm up as they cool. Steer clear of crunchy or extremely thick peanut butters, as they make dough difficult to shape. Enhance your treat by folding in chocolate chips, dried fruit, or a chopped candy bar. Enjoy your delectable creation!

Storing Guidelines

Wondering how to store leftovers? Here’s a friendly guide to keeping your treats fresh:

  • To maintain freshness, place cookies in an airtight container at room temperature. They should stay good for up to 2 weeks. If you prefer to refrigerate them, they can last up to a month.
  • When freezing cookies, wrap them in parchment paper, then place them in a ziplock bag or shallow container. They’ll maintain their taste and quality for up to 6 months.

Using a Silpat cookie sheet makes baking and cleanup a breeze, while a cookie scoop ensures consistently-sized treats. Parchment paper is great for storing cookies in the freezer or lining a baking tray.
