First, preheat your oven to 325 degrees and grease a 12-cup muffin tin well with butter or cooking spray. Whichever you prefer!
In a small bowl add the coconut oil and maple syrup and mix well. Add the eggs and mix to combine. Add the mashed banana, milk, and vanilla and stir to combine. Add the soda, salt, cinnamon, whole wheat flour, and oats. Stir until the mixture just comes together! Add the chocolate chips and stir!
Place your mix into each muffin cup, sprinkle the tops with a few chocolate chips and some raw oats if you'd like! Bake for 23-25 minutes or until you use a toothpick to see when they're ready!
Let the muffins cool in the pan. And enjoy!
