One of our very favorite back to school treats are these blueberry oatmeal breakfast bars. This breakfast bar recipe is great for rushed school mornings. We will often make a batch, enjoy a few fresh out of the oven and then wrap and freeze the rest.

Blueberry oatmeal bars also great paired with coffee or tea. These blueberry oatmeal bars are a sweet treat that are also delicious paired with ice cream or homemade Cool Whip.

How this breakfast bar recipe comes together

These breakfast bars are not only delicious, they’re also super-easy to make. The blueberry filling can be made with either fresh or frozen blueberries, great for any time of the year. The oatmeal crust is amazing, as the brown sugar and oatmeal keep all the juices in the bar perfectly.

You’ll begin my mixing together the oatmeal brown sugar crust by combining the oatmeal, flour, brown sugar, soda and salt. Melt the butter, and pour over the oatmeal mixture. Mix together until incorporated and crumbly. Press 2/3 of the oatmeal mixture into a 9×13 pan, saving the other 1/3 for the topping.

Mix together the blueberries and sugar, and pour over the bottom crust, making sure the berries are evenly distributed over the crust. Then, top the berries with the remaining 1/3 of the crust. Simply crumble over the top of the berries.
