Mix the dry ingredients in a large bowl (flour, oats, baking powder, baking soda, salt, cinnamon).
Mix the wet ingredients in a small bowl (applesauce, egg, milk, vanilla).
Make a well in the dry mix, and add in the wet ingredients and chocolate. Stir the batter only until the dry ingredients are moistened (about 10-13 rotations of the bowl).
Using an ice cream scoop or 1/4 cup measurement, divide the batter among ten lined muffin cups.
Bake 12-16 minutes, or until springy to the touch.
Cool a bit and enjoy!
