To make a jelly roll, you spread jams, jellies, frosting, or whipped cream onto a thin, flat cake, and roll it into a log. While they may look complicated, they're not, says Cooking Light Test Kitchens staffer Kathryn Conrad. Just use a small, rectangular terry cloth or tea towel when rolling to remove moisture and prevent the cake from sticking.
You'll need: A jelly-roll pan, which is a shallow rectangular pan with one-inch-deep sides, and a kitchen towel.
Step One: First, spray the pan with cooking spray, line with a sheet of wax paper, then coat the wax paper with cooking spray. "Spraying both the pan and wax paper will prevent the cake from sticking," Conrad says. Next, pour the batter, and bake.
