If you like layered wafer cakes and would like to make some on your own but you have no possibility to buy wafer sheets (my advice: Polish or Russian groceries!), you can use butter cookies instead of wafer sheets and fill them with the same filling as you would do when using wafers. This kind of cookie layered cake will ressemble German layered cookies-chocolate cake, called Kalter Hund (cold dog) which I am going to post soon.

500 gr butter biscuits (petit beurre / Leibniz type)
1 cup sugar
2 tablespoons flour
2 tablespoons cocoa powder (the pure one, without sugar or powdered milk)
250 gr margarine (no butter!)
1 pack vanilla sugar + a pinch of salt
5 tablespoons milk
10 butter biscuits, ground
1/2 cup peanuts, crushed
1. Melt margarine in a saucepan. Add flour, whisk and bring to boil. Add sugar, cocoa and milk.
2. Whisk eggs with vanilla sugar and salt. Add to the saucepan together with ground biscuits and crushed peanuts (peanuts, if salted, should be covered with boiling water first to melt saltiness) and reheat, stirring all the time.
3. Prepare a tray and cover it well with kitchen aluminium paper or baking paper just like you did with Polish custard cake on crackers. Spread some filling (not more than 5 mm) and cover with next layer of biscuits. Repeat until filling is over. The last layer should be cookies. Cover with aluminium sheet, set in the fridge and put something heavy on the top of the tray. Leave overnight.
Of course, this filling is great to be used with typical waffers. the amount of cookies depends on teh thickness of your filling layers and of the size of your tray.
