Hmmm, they call it "Knotty Cake"
Polish Knotty Cake: Unique Table Accent Becomes a Tasty Dessert
Senkach, or Polish knotty cake, is as spectacular to look at as it is to eat. This golden cake, still handmade in Poland from the original recipe on a rotary spit over fire, forms a hollow tower flavored with vanilla and almonds. Believed to come from medieval Eastern Europe, knotty cake has long been a feature at both royal and workaday celebrations. You can slice it and serve toasted, or fill it with custard and dribble chocolate over it, whatever your imagination or tradition inspires. Each 8.8 oz. cake serves 5.
Sounds good, maybe I'll order some;
