Kolaczki are traditional Polish pastries that are often filled with fruit preserves, sweet cheese, or poppy seeds. They are typically made from a rich, buttery dough that is rolled out and cut into squares or circles. The filling is placed in the center, and the dough is folded or pinched to create a pocket, then baked until golden. These delightful treats are popular during holidays and special occasions in Poland and among Polish communities worldwide. Kolaczki can be dusted with powdered sugar for added sweetness and are enjoyed with coffee or tea, making them a beloved snack or dessert.
