Yes, you can use aluminum foil to make certain desserts, particularly those that are baked or require a mold. Aluminum foil is non-stick and can be shaped into various forms, making it suitable for creating molds for desserts like chocolate molds or for lining baking pans to prevent sticking. However, it's important to use aluminum foil that is food-safe and to avoid using it at very high temperatures, as it can melt or react with acidic ingredients. Always ensure that the foil does not come into direct contact with the heat source to prevent burning.
