Preheat ya oven to 350°F.
Mix together the bananas, egg, oil, vanilla, and yogurt until fully combined.
In a separate bowl, combine the flour, baking powder, baking soda, salt, cinnamon, brown sugar and granulated sugar.
Mix the wet ingredients into the dry ingredients until just combined.
Fold in the chocolate chips, and equally portion out the batter into the sprayed muffin top pan.
Sprinkle on more chocolate chips if you see fit. I always like a few to pop out on top.
Bake for about 20 minutes or until the muffin tops are golden brown and bounce back when slightly pressed on.
Remove from oven and let cool (at least a little bit) before devouring.
