The BEST Banana Bars wit Cream Cheese Frosting are the BEST thing you will ever eat! They are easy to make and so darn delicious. They are dangerously good…I could eat the entire pan!

The Bananas

Once you make The Best Banana Bars with Cream Cheese Frosting you will never use those ripe bananas for anything but these Banana Bars! So long banana bread!

You will need to use ripe-really ripe bananas for this recipe! Did you know that the more ripe/black and spotted your bananas are the more strong of a banana taste they have? Not to mention they mash up much easier for baking!

So let those bananas sit out for a few days and do not throw them away (or make banana bread)- make The BEST Banana Bars!

The Banana Bars Cake

Preheat your oven to 375 degrees. You can use your stand mixer with the paddle attachment, a hand mixer or mix the cake by hand.

You will cream your butter and sugar together first. Then, add in your eggs, sour cream and vanilla and mix well.

The sour cream seems weird, but I promise it doesn’t make the cake taste weird it just makes it super soft! (Try my Super Soft Sugar Cookies that are made with sour cream- you won’t be sorry!)

Last, add your baking soda, salt and flour. Mix well.

Pour your cake batter into a greased half sheet pan. Bake for 20-25 minutes.

The cake is done when the edges of the cake are golden brown and pulling away from the edges of the pan. A toothpick will come out clean when poked in the center of the cake when the cake is done.

Take the cake out of the oven when it is done and let it cool completely while you make the frosting.

The Pan for The BEST Banana Bars

You will need a half sheet pan to make these banana bars. It measures about 18×13 inches on the outside of the pan, and is about 1 inch high.

This is the half sheet pan I love and use:

Cream Cheese Frosting

All you need for the perfect cream cheese frosting is softened butter, softened cream cheese, vanilla extract and powdered sugar.

Using a stand mixer with the whisk attachment, a hand mixer or by hand, add all of the ingredients together and mix well!

TIP: Make sure the cream cheese and butter is fully softened (I let mine sit out on my counter for a good hour or more). If they are not fully softened your frosting will be lumpy- still yummy but lumpy!
