One of the most well-known traditional cakes from the Silesia region of Poland is kołocz – a rich yeast cake topped with a buttery crumb topping. Kołocz comes in several varieties, including with a poppy seed filling like this version.
This Polish yeast cake is easy to make but does take some time – well worth the effort!
Kołocz is best enjoyed with a glass of milk or a cup of coffee on the side.

Where Did Kołocz Come From?
Kołocz has its roots dating back to old Polish kołacz wedding cakes. It was originally considered a ceremonial bread, with the baking process accompanied by singing and prayers to wish the newlywed couple happiness and prosperity. The three most common fillings are poppy seed, cheese, or just the crispy crumb topping.
In Silesian tradition, about a week before their wedding, the soon-to-be-married couple would go from house to house delivering boxes of fresh-baked kołocz to guests, neighbors, and friends. Each box contained both the poppy seed and cheese-filled varieties. Between the two cakes, they placed a white paper napkin and a sprig of myrtle on top as symbols of youth, fertility, and purity.
While the tradition isn’t as widely celebrated today, kołocz remains a popular treat in Silesia, often served at weddings, festivals, and holidays.
