The humble baking cup, also known as a cupcake liner, has many different synonyms. Some refer to it as a muffin liner or a paper baking cup, while others call it a cupcake wrapper or a baking cupcake cup. Silicon baking cups are also popular and referred to as silicon cupcake molds or silicon muffins molds. Some people may even use the term patty pan or fairy cake cases to describe these small baking cups. Whatever name you prefer, they all serve the same purpose - to provide a non-stick, convenient container to bake individual cupcakes or muffins.
