It started with a rich bread dough containing flour, yeast, milk, eggs, sugar, butter, cardamom. After the first rise, I rolled it out, added butter and folded the dough. Chilled it in the fridge, took it out, folded and rolled again. Repeated several times. Then it was rolled out, and spread with, yes, more butter, sprinkled with sugar and citrus peel. It was cut into slices and baked in a muffin tin.
Great with cream cheese frosting.
