In a large bowl, whisk together the milk, pumpkin puree, egg, vanilla, and maple syrup until smooth. Then fold in the oats, baking powder, pumpkin spice, cinnamon, and salt. Lastly, fold in the additional add in's, whatever you'd like them to be. Scoop the mixture evenly into the prepared muffin tins.
