If you slice off razor thin slivers of jam filled chocolate mudcake covered in buttercream it’s absolutely divine. I ate a quarter of a cake that way once.
I don’t know if it has a name but it’s basically a sponge cake with custard cream topped with gooseberry jelly mixed with apple slices. Also it’s sprinkled with roasted coconut flakes.
