These fluffy Banana Bars with Cream Cheese Frosting are so simple to make, and the whole family will love them! The cinnamon cream cheese frosting perfectly complements the sweetness of the bananas. I’m warning you now, these are addicting!

Say goodbye to banana bread, because after trying these banana bars, this may likely be the only recipe you’re going to want to use those prime, overripe, generously speckled bananas for. I’m pretty sure I could have finished the whole pan on my own!

These bars are so amazingly moist, with the perfect combination of flavors. You get tons of banana flavor (notice there’s nearly equal portions of banana to flour) with a pinch of warm cinnamon flavor.

Then you get just a hint of richness from the sour cream and cream cheese along with the perfect balance of sweetness, then to finish an ever so slightly salty crunch from the pecans.

I love the simplicity of this banana bars recipe. I created it to be a one bowl recipe (granted, you’ll have to wash the bowl to make the frosting). All you have to do is toss all the ingredients into one mixing bowl, stir for 2 minutes and bake, bada bing bada boom! Love it.

I thought about creating this recipe to be a sheet pan size, but good thing I didn’t because I would have had a very hard time restraining myself from being engorged by these banana bars.

How to Make Banana Bars with Cream Cheese Frosting

  • Preheat oven to 350 degrees F.
  • Combine all ingredients (except pecans and cream cheese frosting) in a large bowl and mix until combined.
  • Bake in 13×9-inch pan for 25 minutes.
  • While the banana bars cool, make the cream cheese frosting.
  • Frost the bars when completely cool.

Can I Use a Sour Cream Substitute in These Bars?

Without having tested it myself, I can’t say for sure whether a sour cream substitute would work in this recipe. But you may be able to achieve the same results with plain Greek yogurt.

Can I Make These Banana Bars in a Smaller Pan?

Yes, you can also make these banana bars with cream cheese frosting in a 9×9-inch pan (you’ll need to increase the cook time, though!). three banana bars stacked on a plate

Can I Make These Gluten-Free?

I’ve only made these banana bars with sour cream as written, so I’m not sure if you can make them gluten-free. However, a few readers have reported success using gluten-free flours like Cup4Cup. If you make these banana bars gluten-free, please leave me a comment!

How to Store Banana Bars with Cream Cheese Frosting

Since these are banana bars with cream cheese frosting, you’ll need to store them in the fridge. Keep them tightly sealed or store them in an airtight container to prevent them from drying out.

Tips for the Best Banana Bars

  • For thicker, cake-like bars, either bake these in a 9×9-inch pan or make 1.5 the recipe and bake in a 13×9-inch pan.
  • Use overripe, almost black bananas for the richest flavor.
  • If you don’t have applesauce on hand, you can add extra vegetable oil to this recipe instead.

Ingredients

Instructions

  • Preheat oven to 350 degrees F.

  • Bake 25 minutes or until toothpick inserted into center comes out clean. Cool completely, about 1 hour (I'd recommend covering with saran wrap after cooling 20 minutes to help retain moisture). 
  • Frost with Cinnamon Cream Cheese Frosting and sprinkle optional chopped nuts evenly over top. Cut into bars.

Notes

*A few people have commented below mentioning that these bars seem a bit thin. If you want a thicker, more cake like bar then either make 1.5 the recipe in a 13x9 pan, or do just 1 of the recipe in a 9x9 pan and bake a bit longer. I personally like the thinness (it makes them more bar-like) so I make them just as listed, but make them according to what you prefer.
