Do you have ripe bananas on your counter? These Banana Bars with Cream Cheese Frosting are guaranteed to get a thumbs up from everyone!

An easy banana bar recipe with cream cheese frosting that always disappears! Perfect for large groups or an after school snack.

Am I the only one who always has ripe bananas on the counter? And in the freezer? I swear we can’t eat them fast enough. Or maybe I overbuy so I have some ripe ones on hand for baking? All things banana are a hit in this house, like Banana Bread, Banana Muffins and even Slow Cooker Oatmeal. But nothing makes a day better than coming home and seeing a pan of Banana Bars with Cream Cheese Frosting sitting on the counter.

Whenever I want to have a special snack, I know these banana bars will get a thumbs up from everyone. These take 5 minutes to mix together and can be eaten frosted or right out of the oven. We prefer ours cold, but I always test a corner before they get frosted. The smell is just too tempting when they come out of the oven! 

Recommended Equipment:

Filled with mashed banana and slathered with cream cheese frosting, these bars are the perfect combination of dessert and banana bread.  And since they make a big pan, they are perfect for a crowd. Don’t have a group to feed? No worries, just pop them in the freezer and pull them out when the craving hits. Instant gratification.

    My bananas sitting on the counter can’t get brown fast enough! I’m hoping to make this one on Saturday. Love banana bread and the cream cheese frosting might just put it over the top!

      Hi Amy, Sure! It will be more cake like than bar like just because of the thickness, but will still taste delicious!
