Metal muffin molds feature a non-stick coating that eliminates the need for greasing. You don’t need paper liners; just pour the batter directly into the baking mold—this prevents the batter from sticking and ensures all muffins have a uniform shape. The same applies to silicone muffin baking molds. Thanks to the smooth surface, the baked muffins can be easily removed from the mold. The muffin baking molds can be easily cleaned by hand with a damp cloth or under running water.
