I recommend using a ripe banana to bring as much sweetness as possible to your loaf! If yours are still kind of green, don't worry. Here are some tips on how to quickly ripen your bananas: If you have a day or two before you’re planning to bake, put your bananas in a brown paper bag overnight. Bananas naturally release ethylene as they ripen. The bag traps the ethylene, allowing the ripening process to happen faster. Adding an apple, pear, or avocado to the bag will also speed up the ripening process.  If you need to ripen your bananas ASAP, you can also use your oven! Preheat to 350°F and bake your bananas with the peel on for 20-30ish minutes until they’re browned and soft. Allow your bananas to cool in the fridge before peeling and using them in this recipe.
