In a large bowl, stir together the oats, coconut, baking powder and cinnamon.
In a separate small bowl, whisk together the eggs, coconut milk, coconut oil, and maple syrup. Pour the liquid ingredients into the oats mixture and stir well to combine.
Pour into a greased 8x8" or 9x9" square baking pan.
Bake for 40-45 minutes, until lightly browned at the edges and dry in the middle.
