Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper.
02 -
In a large bowl, mix the flour, baking soda, baking powder, salt, and cinnamon (if using).
03 -
In a separate bowl, whisk together the mashed banana, yogurt (or additional banana), maple syrup (or honey/agave), oil (or milk), and vanilla extract.
04 -
Pour the wet ingredient mixture into the dry ingredients. Stir until just combined to form a batter.
05 -
Transfer the batter to the prepared loaf pan. Smooth out the top and, if desired, press some chocolate chips into the surface.
06 -
Bake on the center oven rack for 40 minutes. Without opening the oven, turn off the heat and let the bread sit in the closed oven for an additional 10 minutes.
07 -
If the bread is not fully cooked after this time, cover the top with foil. Turn the oven back on and bake in 5-minute increments until a toothpick inserted into the center comes out clean.
08 -
Let the bread cool completely. Cover and refrigerate overnight for improved taste and texture. Leftovers can be sliced and frozen for up to a month.
