Peel, cut, and mash the bananas in a bowl (I prefer to do this with a masher or my washed hands).
Add all dry ingredients into the same bowl. Add oil in the end.
Mix with a electric mixer. Add more cinnamon if needed.
Line the bottom of a 8" pan with a circular 8" piece of wax paper and pour batter in the pan (you can also use a bread pan, but i prefer using a circular pan). Sprinkle some cinnamon on top before baking.
Bake bread in oven for 50-55 minutes.
Let bread cool completely and turn over onto a rack or cutting board. Peel off the wax paper and cut into square pieces or slices! Enjoy cold or hot!
Notes
For a healthier option, try one or more of the following options:
Use whole wheat flour instead of white flour
Instead of 3/4 cup sugar, use 1/3 cup sugar + 4 tbsp applesauce
Gluten-Free Option - use a gluten free all-purpose baking mix (such as from Arrowhead Mills or Bobs Red Mill)
