Definition
A jellyroll is a type of sponge cake thatβs baked in a shallow pan and then rolled up with a filling, usually jam or jelly. π The result is a spiral-shaped cake with a sweet center. It requires a flexible cake that won't crack when rolled. Think of it as a cake version of a burrito, but filled with sweetness instead of savory ingredients. It's often dusted with powdered sugar for a pretty finish.
