So.
For this to work you need some kind of a relatively hard, dry, semi-sweet, no buttery biscuits. We call it "household biscuit", I know this info isn't helpful.
Anyway, ingredients:
- biscuits
- sour cream
- sugar
- vanilla sugar
- cocoa
- jam (any kind of fruit will do I think)
You make three mixes from the sour cream and the other ingredients, one with cocoa and sugar, one with the vanilla sugar (plus sugar probably), one with the jam.
Get some container, spread one of the creams, then lay a layer of biscuits. Spread the next cream, then a layer of biscuits. Spread the third cream.
Let it rest in the fridge. When the biscuits turned soft, eat it.

Optionally I'm sure it can be made with other flavorings, like coffee or coconut and so on.
