Lightly coat an 8x8 inch baking dish with cooking spray (bottom/sides). Preheat oven to 325° F.
In a large bowl, combine oats, 3/4 cup chopped pecans (reserve remaining pecans), cinnamon, salt and baking powder. Stir until ingredients are mixed. Set the bowl aside.
In a separate bowl, place milk, egg, plain Greek yogurt, maple syrup, melted coconut oil and some vanilla extract. Whisk these "wet" ingredients together, until fully blended and creamy. Set the bowl aside.
Evenly distribute the blueberries and then chopped apples on the bottom of the prepared baking dish. Sprinkle the oats and pecan mixture evenly over the fruit layers, to cover. Pour the milk/yogurt mixture over the oats. Using the back of a spoon, press down firmly all over the surface of the oats, so the dry oat mixture is submerged into the liquid. Sprinkle the remaining 1/2 cup chopped pecans evenly over the oats.
Bake at 325° F. for approximately 40-45 minutes. When done, the top of the oatmeal will be a nice golden brown color, and the oats will be "set", not sloshy. Remove pan from the oven. Let it cool on a wire rack. Blueberry baked oatmeal can be served warm, or at room temperature (our favorite=room temp.). When ready to serve, slice into 8 portions, transfer to plates, and enjoy!
