Preheat oven to 375 degrees F. Spray a muffin tin with non-stick baking spray or line with paper liners.
In a large mixing bowl, add the flours, oatmeal, baking powder, baking soda, cinnamon, salt, and turbinado sugar. Whisk together to combine.
Grate the apple and put it into a large bowl. Add the almond milk, egg, vanilla, and coconut oil to the bowl and mix them with a spatula.
Pour the wet ingredients into the bowl with the dry ingredients and mix with a spatula until they are combined.
Fill the muffin tin equally, about 2/3 of the way full each.
Bake the muffins in a preheated oven for 14-16 minutes. Insert a toothpick into the center, and if it comes out clean they are done
Let the muffins cool in the tin for 10 minutes and then remove and place on a wire rack or large plate to finish cooling.
