Peanut butter. Use sugar free peanut butter to keep the cookies low carb and keto approved.

Lily’s Dark Chocolate Chips. This is our favorite brand of chocolate chips for low carb baking. They’re keto, paleo and gluten free!

Easy Instructions

Make the peanut butter cookie dough:

Combine all the ingredients (except the chocolate) in a stand mixer until well combined.


Roll the dough into balls and place them on a parchment lined baking sheet. Use a fork to press a criss-cross pattern on the top of each unbaked cookie.

Bake in a 350 degree oven for 10 – 12 minutes, then allow to cool completely.

You can enjoy them plain or add a chocolate touch!

For chocolate dipped cookies:

Melt the chocolate chips in the microwave, stirring at regular intervals. Dip each cookie in the chocolate, covering as much of the cookie as you like.

Place dipped cookies on parchment paper while the chocolate sets.

Tips and Tricks

  • For a smoother and softer chocolate coating, add 1/4 teaspoon of coconut oil to the melted chocolate chips.
  • If you prefer a less sweet peanut butter cookie, reduce the monkfruit to 1/4 cup.
  • Add a sprinkle of sea salt to the cookies before baking to bring out even more peanut flavor.
