These Yummy Sour Cream Banana Bars have always been a favorite for as long as I can remember.
They are super moist and decadent due to the ripe bananas, eggs and sour cream used to make them. They're slightly tangy, delicious banana bars with a creamy layer of luscious cream cheese frosting on top to make everyone happy!
This invaluable keep-sake bar recipe is definitely one of those that never get old.
It's classic, traditional and wonderful for after school snacking, bake-sales, potlucks and my favorite reason, just because!!
Do you get excited when you have ripe bananas hanging around?
There are so many banana baked goods you can make, especially here on the blog. Just put 'banana' in the search engine and you'll find a multitude of them.
It's hard to pick a favorite.
So you might as well start with these Yummy Sour Cream Banana Bars! hehe
But, I can throw out some I think are banana-worthy for ya...like these Perfect Banana Milk Chocolate Chip Cookies (seriously yummy!), this Sour Cream Banana Bread, Fluffy Banana Bread Cinnamon Rolls, 19 Delicious Recipes to go ‘Ripe’ Bananas Over and Banana Pound Cake & Milk Chocolate Glaze.
If you don't have sour cream, you can always use plain Greek yogurt as a substitute. Just make sure it's not flavored with vanilla, if you want the slightly tangy factor, like sour cream. (Or try these Heavenly Frosted Banana Bars)
You can frost these with prepared frosting if you want, or buy another other flavor for that matter. You could also dust these banana lovelies with some powdered sugar if you want to cut down calories.
I'm partial to cream cheese frosting especially with these bars...sooo good and tasty!
Plenty of Yummy Sour Cream Banana Bars to go around! They're made in a 9x13 pan.

Notes

So very very delicious!!! I made these last night to bring to my family's Thanksgiving Day feast today... One thing I did switch up though is instead of regular confectioner's sugar for the frosting I opted to use a Keto-friendly alternative! I used Swerve instead! It came out really really good! Just an idea though for anyone wanting to cut out some carbs and sugar but still wanting the taste!
Definitely makes them moist! I've used Greek yogurt too, so yummy! Thank you Christie! xo
I've never tried this before but it sounds so amazing Kim! I love the idea of adding sour cream to make it more moist!
