Peanut Butter Oatmeal Cookie Bars
These peanut butter oatmeal cookie bars are inspired by my wildly popular Flourless Cookies.

These gluten free cookie bars are all things delicious! Not only are they yummy, but they are naturally gluten free, can be made dairy free, and have an added bonus of protein too!
In fact, the ingredients in these bars are so clean that I don’t feel bad letting my kids eat them for breakfast. Each bar has 9 grams of protein!

Serve these cookie bars for breakfast, as a snack, or as dessert and you can’t go wrong. They never last long in our house!
