These Low Calorie 3 Ingredients Peanut Butter Cookie Recipe are easy and fun to make!You can use any peanut butter you like, but I recommend no sugar added, creamy peanut butter for best results.Special Tip: If you don't want the pattern on the tops of the cookies you can skip that. You can also add a Hershey's kiss to the top of all or half to mix it up a bit.
