Preheat the oven to 350 degrees F. Lightly oil a 8" x 8" baking dish.

Stir together the rolled oats, coconut, baking powder, cinnamon and sea salt in a mixing bowl.

Whisk together the eggs, coconut milk, vanilla extract, and maple syrup in a seperate mixing bowl. Add the oat mixture to the bowl with the wet mixture and stir well to combine. Stir in the frozen blueberries and pour the mixture into the prepared baking dish.

Place on the center rack of the oven and bake for 55 to 65 minutes, or until oatmeal has set up and is cooked through.

Remove from the oven and allow baked oatmeal to cool 20 to 30 minutes before serving (Note: if you don't allow the oatmeal to sit after it comes out of the oven, it will fall apart).
