Preheat oven to 350.
In a large bowl, combine oats, cinnamon, flax seeds, vanilla, baking powder, and salt.
In a separate bowl, crack 2 eggs. Slowly add in maple syrup, milk and butter, whisking until combined.
Add wet to dry ingredients, stirring until oats are covered in liquid. Let sit for 5-10 minutes to absorb. Add raisins and chocolate chips in last.
Spray a muffin tin pan with cooking spray and pour oatmeal mixture among the 12 muffins tins, dividing evenly.
Bake for 25-27 minutes or until the tops are slightly brown. Let cool for 5 minutes before serving.
