A jelly-filled donut, also known as a jelly donut or jam-filled donut, is a type of fried pastry that is typically round and soft. It is made from a sweet dough that is deep-fried until golden brown and then filled with fruit preserves or jelly, often made from strawberries, raspberries, or blueberries. The donut is usually dusted with powdered sugar or granulated sugar on the outside. These treats are popular in many cultures and are often enjoyed as a dessert or snack. In the United States, jelly-filled donuts are commonly found in bakeries and are a favorite during celebrations like Hanukkah and National Donut Day. They can be served warm or at room temperature, making them a versatile option for any occasion.
