Jelly-filled pastries are sweet baked goods that feature a filling made from fruit preserves or jelly. Common types include Danish pastries, jelly doughnuts, and kolaczki. These treats are often enjoyed as breakfast items or desserts and can be found in bakeries around the world. The jelly filling can vary in flavor, with popular options including strawberry, raspberry, and grape. The outer pastry is typically soft and flaky, providing a delightful contrast to the sweet, gooey interior. Many people enjoy them with a dusting of powdered sugar or a glaze on top for added sweetness.
