In a separate, medium bowl, whisk the sugar and coconut oil until blended. Add the eggs and beat until smooth. Add the bananas and milk and whisk to blend, then add the baking soda, cinnamon, vanilla and salt and whisk to blend. Add the oats and with a rubber spatula, mix in the flour a little at a time until it is combined. Add the chocolate chips and stir, reserving a handful to sprinkle on the top.
