Lightly coat muffin liners with vegetable oil spray
In one bowl, combine flour, baking soda, baking powder, salt and cinnamon.
In another bowl, mash bananas with fork. Mix in oil, brown sugar, egg replacer, vanilla and soy milk.
Add the flour to the banana mixture and mix until just incorporated (don’t overmix or it will be tough).
Fold in chocolate chips.
Evenly spoon batter into the 10 muffin liners. 10 muffins gives you a nice size dome; 11 would give a more moderate size muffin.
Bake for 5 minutes at 425, and lower to 350 for 15 additional minutes. Check to see if it springs back. If it does, remove from pan and put on cooling rack. Otherwise, cook up to 5 minutes more.
