Everyone has a chocolate cake. This is mine.
Triple layer chocolate cake with chocolate frosting and a lighter creamy chocolate filling.
I had a Pepperidge Farms cake in mind, same as for my Banana cake.
Their chocolate cake had a lighter creamy filling, not just the same frosting as on top.
I wanted that.
The filling is made by slightly modifying an ermine buttercream frosting (AKA butter roux or boiled flour frosting). So not quite making two different icings for the cake.
Ermine buttercream is an old fashioned buttercream recipe I use when I am making a vegan buttercream (using coconut oil). I substitute cornstarch if I need something wheat free. Ermine buttercream is also the original Red Velvet cake frosting. I use a Cream cheese frosting on my Red Velvet though, like most people do these days.
The reason for the name is that it is white, like an ermine, until you add chocolate, like I do here.

This was one of my first cakes at the restaurant and it would remain on the dessert menu to the end.
After all, everyone has a chocolate cake!
