3 Ingredient Peanut Butter Cookies (Gluten-Free)

3 Ingredient Peanut Butter Cookies

These are my new go-to treat! They are gluten-free and they require very simple ingredients. All you need is eggs, brown sugar, and peanut butter! I chose to cut down the usual amount of sugar to make the cookies much healthier. However, this made the cookies chewy as opposed to crispy! If you want to cut down on the sugar without compromising the crunch you can add 3 tablespoons of coconut flour which will soak up a lot of moisture! Personally, I loved the chewy, fudge-like texture! 

Three ingredients for peanutbutter cookies

The batter will look pretty moist. This is because there is nothing to soak up the moisture so you can add 3 tablespoons of coconut flour or another half cup of sugar!
