45 Budget-Friendly Sheet-Pan Dessert Ideas for Feeding a Crowd

When a potluck, picnic, birthday, or family gathering calls for dessert, a wide pan can do the work of several smaller batches. These ideas cover chewy cookie bars, fruit-filled slab pies, frosted cakes, cheesecake, crisp, and cobbler, with practical ways to use ripe fruit, pantry staples, and make-ahead freezer space. Before baking, check whether a recipe calls for a standard sheet pan or a jelly-roll pan, and line the pan when neat removal matters.
