What can be a substitute for cupcake liners?

* Parchment paper. Parchment paper is a great substitute for cupcake liners because it is heat-resistant and non-stick. You can either cut parchment paper into circles or use a muffin tin to shape it.

* Aluminum foil. Aluminum foil is another heat-resistant and non-stick option. You can either cut aluminum foil into circles or use a muffin tin to shape it.

* Muffin tin. If you don't have any cupcake liners, parchment paper, or aluminum foil, you can simply grease a muffin tin and pour the batter directly into the cups. This will work best if you have a non-stick muffin tin.

* Silicone baking cups. Silicone baking cups are reusable and come in a variety of shapes and sizes. They are a great option for cupcakes because they are flexible and non-stick.

* Ice cream scoops. Ice cream scoops can be used to measure out the batter and drop it into the muffin tin. This will help to ensure that all of the cupcakes are the same size.
