To make quick and easy cornbread in a truck, the host only needs jiffy corn muffin mix, egg beaters instead of whole eggs, and a little bit of milk. The ingredients are combined in a bowl, then poured into a disposable baking tin. A Crockpot is used in place of a traditional oven for baking by removing the glass interior. Place the tin with the mix directly inside, and cover until baked fully. The host usually uses a small tin that will fit easily inside the Crockpot, but if only a larger one is available it can be molded to fit inside.
