Yes, you can use aluminum foil to create a makeshift cake pan. To do this, you'll need to form the foil into a pan shape, ensuring it's deep enough to contain the cake batter and has a bottom to prevent leakage. Grease the foil well to prevent the cake from sticking. However, it's important to note that this is a temporary solution and not ideal for baking as aluminum foil can buckle or tear under the heat, potentially leading to uneven cooking or mess. A proper cake pan is recommended for best results.
