Muffin Cup Case Black Grease Proof (250 per pack)

These cases are ready for use. Place the batter in the case and bake in the oven. 

Do I need to grease the cupcake paper liner? Nope! The grease is for the cupcake batter to not stick to the pan, and the liners do the exact same thing, so you don't have to grease the paper liners as well. ... Cupcake liners always darken as the cupcakes cook.
