I found some old photos of cakes I made when I had more free time to experiment.
Here is the Cordon Rose Banana Cake with probably the sour cream ganache. It’s been close to ten years, I’m guessing.
There is also a chocolate cake with vanilla buttercream (I don’t recall which buttercream. Could be Classic, NeoClassic, or the recipe in the Kitchen-Aid manual.) and Strawberry Fruit Cloud Cream, topped with chocolate covered strawberries. From the date on the photo (2/13/2000) It must have been for Valentine’s Day. It was really yummy.
