Preheat the oven to 375°F.
Spray an 8-inch square baking dish with cooking spray.
In a large bowl, mix together the oats, baking powder, cinnamon, nutmeg, and salt.
Add in the milk, maple syrup, egg, coconut oil, vanilla and bananas. Stir well to combine.
Fold in 1 cup of blueberries.
Pour oatmeal mixture into the prepared baking dish.
Add the remaining blueberries across the top and top with pecans if desired.
Bake for 40 to 55 minutes or until the middle of the bake is golden. Let cool for a few minutes and serve warm! Top with ice cream, if you must! No judgment here!
