Preheat oven to 375 degrees.

Spray a 9X9 ceramic baking dish with cooking spray, or lightly oil.

Dice the bananas into the dish, in a single layer. Sprinkle 1 cup of the blueberries over top of the bananas. Drizzle the blueberries and bananas with 2 tablespoons of honey.  I didn’t measure, just a drizzle over the top.  Sprinkle with half of the cinnamon.

Bake in the oven for 15 minutes to soften the bananas.

Meanwhile, in a medium bowl mix oats, ¼ of walnuts, salt and baking powder.

In a small bowl, whisk remaining honey, milk, vanilla and egg.

Once fruit has been removed from the oven, sprinkle oat mixture evenly over top of fruit.  Pour egg and milk mixture over the oats using a spatula to push into the corners. Sprinkle remaining blueberries and 2 tablespoons of walnuts over the top.

Bake for about 20 minutes, remove from oven and sprinkle with sugar (if using) and return to the oven to complete cooking. It will bake for 30-35 total or until it is golden brown on top and oatmeal is set. The sugar adds a little bit of crunch to the top, but you can easily skip this step.

Serve with additional milk or cream, I used soy milk. This is nice and sweet, you can serve with syrup or honey on the side, but try it without. I find it doesn't need the extra sweetness.
