I wanted to make this cake for a long time, since one does not have to do any baking for it whatsoever. We have a candy bar in Poland called this way. It’s a mix between caramel, cookies and chocolate. To be completely honest I prefer this cake over the candy any time. The recipe is a combination of many. They all say pretty much the same with the exception in preparation of a custard cream. Some boil the butter with milk and sugar and some just boil everything and mix it with butter when the custard is cool. So or so it is worth trying! Enjoy!
