Turning Extra Bananas Into Cake
I know, I know… always with the banana recipes. You guys, I can’t help it!
I am not sure if you are thanking me or cursing me, so I choose to think you are loving this crazy banana baked good roller coaster. Here’s what happened:
Little Dude went on a banana bender. He HAD to have one every night before bed for a couple of weeks running.

Our supply was dwindling quickly, so I bought another bunch and then the bedtime banana ritual stopped as quickly as it started.
You never know with this kid. So the bananas sat.
And ripened. And ripened. And sat.
Until there was only one thing to do, BAKE! Boo hoo!


But if you are supposed to make lemonade out of life’s lemons, I figure you should make banana cake out of life’s overripe bananas too. It only seems right.
We had dinner planned at my brothers’ house on Friday, so I offered to bring dessert. We loved the combo and banana and caramel on Di’s Banana Cake. So, I thought I would switch it up a bit.
I love sheet cakes. They are so easy to put together.

They can be cut into teeny tiny squares for the strange people who “don’t really like sweets.” What does that even mean?!
Or great big giant bars for those of us who practice portion control by only having one piece, no matter the size.
The Icing
Now let’s get to the frosting. MMMMM, frosting! Of course, one of my favorite parts of any cake.
I wanted the creamy feeling of cream cheese mixed with a rich caramel flavor. This icing is still a bit warm when you spread it, so it goes on super smooth and then it sets up a bit as it cools.


You can certainly adjust how salty you would like your salted caramel. I’d suggest you put at least a quarter teaspoon in for balance. I went full boor and put almost a whole teaspoon in.
Then for added affect, I sprinkled a couple of grains of super coarse sea salt on a few pieces as I served them. It added a little crunch an that pop of salty sweet flavor. So fun!

We love banana baked goods around here. Whether it’s banana chocolate cupcakes or something a bit healthier like banana baked oatmeal, it’s bound to be a hit with our crew.
If you are looking for a banana cake that’s ready for a party, check out the star-spangled banana cake. It has 4 layers of moist banana cake, loads of fluffy white frosting and a sprinkling of coconut.
If you aren’t in the mood to bake, banana rice pudding is a great option. Or your can freeze them and turn them into chocolate peanut butter nice cream.
