Banana Cake with Vanilla Bean Frosting is my favorite banana cake recipe. The frosting is so creamy and good, you may just want to grab a spoon.
This cake…let me just tell you…is delicious.
This frosting…let me just warn you…is amazing.
It is my new favorite frosting. I will be using it in place of any other vanilla frosting. Even store bought, which I really love. It has heavy cream in it. Enough said.

I will never use milk again to make frosting. Never Ever. Only heavy cream for this mama. I can’t even describe the amazingly creamy difference.
