Moist Banana Bars
For 27.75 years of my life, I just figured I didn’t like cream cheese frosting. Just like I thought I didn’t like cheesecake when I was younger because it had the word “cheese” in it.
Same thing goes for cream cheese frosting. But I got adventurous one day (yes, I’m laughing at this now!) and tried cream cheese frosting on cake, and what can I say?
It’s dreamy. It’s even better when paired with banana cake. Banana cake with cream cheese frosting were meant to be best friends.

How to Ripen Bananas Quickly
To ripen bananas quickly, turn your oven to 300º F, place the bananas (with peels still on!) on a baking sheet and place them in the oven for 15-30 minutes. You want the peels to turn black and the bananas to be soft.
How to Store Banana Bars
Unfrosted banana bars can be covered in an airtight container and stored at room temperature on the counter for up to 3 days. For longer storage, place in the fridge.
If they are frosted with cream cheese frosting, store them in an airtight container in the refrigerator. My husband actually prefers them cold, straight from the fridge!

Banana Bar FAQs
A jelly roll pan is a cookie sheet or baking sheet that has a raised edge. Our recipe calls for a 10.5 x 15.5 inch pan.
If you don’t have the specific size of pan, bake these bars in a 9×13 inch pan. The bars will be thicker and require a longer baking time. If baking in a 9×13 inch pan, check the bars at 25 minutes and adjust the baking time as needed.
