Not spraying the pan or using liners
The topic of cupcake liners is quite contentious. Are they necessary or not? Cupcake liners help cupcakes maintain their form and moisture for a longer period of time. When eating cupcakes, they also assist in maintaining cleanliness. While both of these statements are accurate, if you just ran out of liners, try not to become upset. If you follow only one important guideline, cupcakes will turn out just fine if you pour the batter directly into the pan.
Using cooking spray is considerably more significant than whether or not you choose to use cupcake liners. There is a possibility that your cupcakes will stick to the paper even if you use liners. Cooking spray should be liberally applied to the pan or the cupcake liners before you scoop the batter into the pan. If you don't have cooking spray, you may coat the molds with a brush soaked in melted butter. You should place a baking pan with water inside on the bottom level of your oven to add moisture to the environment while the cupcakes bake and help prevent them from sticking.
