(177°C). Grease a standard 9×5-inch loaf pan and add a strip of parchment paper for easy removal, if desired.
In a large mixing bowl, mash the bananas with a fork or hand mixer.
Add the softened butter, sugar, vanilla, and cinnamon (if using) to the bananas. Mix well.
Add the flour, then sprinkle in the salt and baking powder. Gently mix until just combined (avoid over-mixing). Fold in any optional mix-ins.
Pour into a loaf pan and bake for 55-65 minutes, until a toothpick inserted in the center comes out clean. Enjoy!
