add in the flour, cinnamon and baking soda and mix slowly to combine. fold in the chocolate chips.
fill the muffin tins evenly with batter, and top with a slice of banana.
bake at 425 degrees f for 5 minutes to get the tops a bit crunchy, and then reduce the temperature to 375 degrees f for about 15-20 minutes, until a toothpick comes out of the muffin center clean. enjoy!
