Do you have to grease cupcake linings before pouring the batter?

In most instances, it is not necessary to grease cupcake linings before pouring the batter. Cupcake linings are typically made from a non-stick material, which prevents the cupcakes from sticking to the pan. However, there are a few exceptions to this rule. If you are using a particularly sticky cupcake recipe, or if you are using a metal cupcake pan, you may want to grease the liners to be on the safe side. To grease the liners, simply spray a little cooking spray into each cup before filling them with batter.
