Tips for making Banana Bars:
How do you ripen bananas quickly?
To ripen bananas quickly, just pop your bananas in a paper bag, fold over to close and check in a day. The enclosed environment traps ethylene, the compound responsible for ripening bananas. For even better results, add an apple to the bag (it also releases ethylene). Don’t want to wait a day? You can ripen bananas in minutes or hours using an oven or freezer.
What are some alternatives to cream cheese frosting?
It’s hard to go wrong with a creamy caramel frosting. Feeling a bit more adventurous? Why not go Elvis-inspired with a chocolate peanut butter frosting? Spread over the top, then sprinkle the banana bars with chopped peanuts or crumbled cooked bacon!
What other toppings can you add to banana bars?
Try your hand at a classic homemade chocolate ganache. Cool and spread over the top, then decorate with dried banana chips or chopped pecans. Or, for the simplest topping of all, lightly dust with confectioners’ sugar.
