First preheat the oven to 350 degrees.
Mash the bananas and melt the butter. Add the butter to the mashed bananas in a large mixing bowl. Add the remaining wet ingredients (discard, eggs, vanilla extract).
Mix the wet ingredients using a stand mixer and paddle attachment, hand mixer, or whisk.
Next, in a medium mixing bowl, mix the dry ingredients (flour, sugar, baking soda, salt, cinnamon).
Slowly add the dry ingredients to the wet ingredients and mix well. Do not over mix. If using, fold in chocolate chips or pecans.
Grease the bread loaf pan with non-stick spray (or line with parchment paper) and pour the batter into the pan.
Bake the banana bread in the preheated oven for 50-60 minutes, until a toothpick or butter knife inserted into the center comes out clean.
Allow to cool for 15 minutes on a wire rack before cutting. Serve warm with butter!
Store in an airtight container on the counter for up to a week, or leave in loaf pan covered with aluminum foil or plastic wrap.
