I always buy a bunch of bananas. I like to freeze some smoothies and I used to have to find the patience to wait for the rest to get super ripe to make banana bread. But if you're in the same waiting boat, I have some tips for ripe bananas FASTER.
You can ripen bananas faster two ways. 1) Leave them in a paper bag. This will still take a day or two, but will ripen them faster than if you just leave them out on your counter. 2) Baking them at a lower temperature in the oven. This will turn the outside of the banana black, but don't worry, the inside will be perfectly ripe for your banana bread.
