I saw something called a chocolate blackout cake: chocolate cake, chocolate pudding in the layers, and chocolate ganache coating.
I made a variation with gluten free vanilla cake (fortified with vanilla pudding mix), vanilla and salted caramel pudding in the layers, and a sour-cream Caramilk ganache coating. The fruit iss raspberries. There were also Caramilk and peanut butter flavored chips.
It went alright. There is a significant amount left over.
