Oatmeal Brownies

These oatmeal brownies are some of the best, healthy, easy brownies we've ever tasted and they travel extremely well.

In addition to being easy to make they are full of heart-healthy oats.

Did you know that quick-cooking and old-fashioned rolled oats are interchangeable unless the recipe calls for a specific type.

On the other hand, instant oatmeal is not the same and should not be used for baking.

Bake up a batch of these sweet and wholesome brownies with oatmeal for your next casual gathering, picnic, or potluck.

This recipe makes a big batch of Oatmeal Brownies so you will have plenty for sharing. These brownies are perfect for tucking into lunch boxes too!
