Muffins, cupcakes, individual-sized quiches—all are made quickly and easy with a commercial muffin pan. Muffin pans are sold in a variety of sizes, like supersized family-style cupcakes or miniature-sized desserts, perfect for impulse buys from hungry customers. If you're a serious baker, you'll want to count one (or more like five) muffin pans in your arsenal of tools.
