⬇️How to make this a "for two" friendly recipe
This is a recipe for a regular 9X13-inch cake pan. And it won't disappoint.
But this is "cooking for two," and this is an easy recipe to cut in half. You will need to use a 9-inch round or 8-inch square cake pan. The baking time will decrease to about 30 minutes but use the toothpick test.
It also makes an excellent layer cake with two round 9-inch pans and the optional cream cheese frosting.
❓FAQs
When we sift flour, it breaks down any clumps and provides a fluffier result. It also helps mix other ingredients though out the flour. It will improve the texture a bit. If you don't have an old-school flour sifter, you can get about the same effect using a large fine-mesh strainer.
If you don’t have time for over-ripe bananas now, peel and freeze for a few months until you are ready to bake bread, cake, or muffins.
As bananas ripen, enzymes convert some of the starch to sugar. This makes for great sweet banana bread, muffins, or even cakes.
Yes, due to the cream cheese.
❄️Storage
Without the frosting, this can be stored at room temperature for 3-4 days, tightly covered. With the frosting, it should be refrigerated.
It will also freeze well for several months with or without the frosting.

In the ingredients you listed 2/3 cup chopped walnuts, but in the instructions you listed 3/4 cup. Either one works, just thought I'd let you know. I meant to bring this to your attention when I made it before and told you about the typo on the sugar amount back on 2-15-20.

Thanks for the note/proofread. Fixed. My bad as they say.

Made this tonight with some very ripe bananas I had laying on the counter. Very easy to make (I added the cream cheese as a bonus). I have to rate this one a solid 5! Thanks Dr D!
Claudia Matusiak
In the cake ingredients you list 1 2/3 cup sugar. In the instructions you only mention using 1 1/3 cups sugar......what do we do with the remaining 1/3 cup of sugar?
Dan Mikesell AKA DrDan
Transcribed wrong...it is 1 1/3 cup. Fixed. Thanks for the proofread.

Can a Bundt pan be used?
DrDan
I don't have a bundt pan so I have never done it. I'm sure it's possible. Some bundt pans are huge and need about double this amount of cake. Also cooking time may be increased some. So the answer is I don't know.
