Grease a 6 muffin muffin tin.

Beat the egg, milk, oil, and vanilla together in a mixing bowl.

Blend the flours, cinnamon, baking powder, and salt together well.

Peel, core and chop the apple. Toss the apple pieces in the flour mix to coat and separate.

Pour the dry mixture into the wet one, and stir until completely blended. Pour into the prepared muffin tin.
