Potato cake is a classic of Soviet cooking. Everyone knows the cake: both children and adults. The dessert appeared in the USSR as a result of massive savings on products. In catering establishments, crumbs and scraps of dried baked goods were collected, rolled in cocoa and served as dessert. Over time, the recipe was improved and the ingredients changed. Nowadays potatoes are prepared with bread, bananas, coconut, oatmeal, rum, etc.
