If you spray a muffin pan do need tins?

It depends!

If you're using a non-stick muffin pan: Spraying it with cooking spray is usually sufficient. You don't *need* paper liners, but they can make cleanup easier and prevent sticking.

If you're using a regular metal muffin pan: You *do* need paper liners or tins. The metal will be too sticky for the muffins to release without them.

Here's a breakdown:

* Non-stick pan + spray = You can skip the liners, but they are helpful.

* Regular metal pan + spray = You *need* liners or tins.

Always check the recipe's instructions. Some recipes might call for liners regardless of your pan type.
