A jelly roll is a type of dessert made from a thin layer of sponge cake that is spread with jelly or jam and then rolled up into a cylindrical shape. The cake is typically baked in a flat pan, making it easy to spread the filling evenly. Once rolled, it is often dusted with powdered sugar or frosted for added flavor. Jelly rolls can be made with various fillings, including fruit preserves, whipped cream, or chocolate. They are popular for their light texture and versatility, making them suitable for celebrations or as a simple treat. This dessert is also known as a Swiss roll in some regions.
