There is something reassuring about having the kind of breakfast that you bake once and eat throughout the week. I am all about trying to multi-task, meal prep, and plan ahead when I can all while avoiding as much pre-packaged foods as possible. Starting the day with a warm breakfast like this Blueberry Banana Oatmeal Bake never fails to be a hit. This laid-back casserole version of a traditional bowl of oatmeal has been pretty popular lately.
Prepare your 9 x 9" pan with non-stick spray and pre-heat the oven to 350F or Gas Mark 4.
In a medium mixing bowl, mash the bananas very well with a fork and combine with eggs, milk, maple syrup and vanilla. Make sure the eggs are also well beaten. Set aside.Note: You can also mix the wet ingredients in the blender for a few pulses just to make sure the eggs and bananas are fully incorporated.
In another medium mixing bowl combine the oats, baking soda, salt, and cinnamon.
Add the dry to the wet ingredients and mix well. Gently fold in 1 1/2 cups blueberries and pour the mixture into your prepared baking pan and spread out evenly. It will be very liquidy, the oats will soak it up as it bakes.
Top off with the remaining 1/2 cup blueberries and bake on the middle rack for 40-45 minutes. It should be set in the middle and lightly browned.
Let rest and cool for 10 minutes then cut into 9 squares. Store in an air-tight container in the refrigerator for up to 7 days.
