Why I Love These Peanut Butter Oat Flour Cookies

Ingredients

Coconut Sugar:
These cookies are sweetened with coconut sugar instead of refined white sugar.
Substitute coconut sugar for brown sugar, date sugar, or any granulated sugar.
Oat flour:
Made from rolled oats, oat flour is a great source of fiber, which can help improve digestion and keep you feeling full.
You can use all-purpose flour, whole wheat flour, or almond flour instead of oat flour.
Peanut butter:
Peanut butter acts as the binder in this recipe.
You can use any nut butter (almond butter, sunflower butter, cashew butter) instead of peanut butter if you are allergic to peanut butter.
Baking powder:
These cookies don't rise a lot, but the baking powder helps add a little lift and create a better texture.
You can also use 1 egg if you don't have baking powder.
What is the best peanut butter to use?
I like to use all natural peanut butter without added sugars or oils because I enjoy the taste and I can feel good about consuming peanut butter that does not contain any added preservatives or ingredients.

What is Oat Flour?
Oat flour is a type of flour that is made from rolled oats. It is a great alternative to regular flour for anyone who is gluten-free or looking for a more nutritious flour option.
Oat flour is high in fiber, protein, and other nutrients, making it a great addition to any diet.
To make oat flour, simply grind rolled oats in a food processor or blender until you achieve a fine, flour-like consistency.
I love using oat flour in many of my desserts including oat flour biscotti, oat flour banana bread, and oat flour strawberry protein bars.
