Maulwurfskuchen - Mole cake (You can guess where the name comes from :D )
A chocolate sponge cake, hollowed out and filled with bananas, chocolate chips, and whipped cream. The crumbs are then used to decorate the dome.
I will post the recipe if someone's interested.
(P.S. No moles were harmed in the making of this post!)
A little vanilla or vanilla sugar would be good in the cream.
I've never used stabilizer because I didn't know it was a thing. The trick is to get everything cold. Metal bowl and whisk, put them in the freezer for 30 minutes or so, and the cream too. Add some sugar, whip by hand, and work fast. The texture is unbeatable, but it doesn't keep long. A day or maybe two, if whatever it's in is well chilled. A cake like this wouldn't last long around me :)
