The terms are commonly used interchangeably, although muffin cups may sometimes be slightly deeper or larger.

Not always. Cases make serving and cleaning easier, while greasing the tray can work for recipes baked directly in each cup.

Muffin trays can also be used for cupcakes, fairy cakes, mini quiches, Yorkshire puddings, egg bites and individual savoury portions.

Follow the recipe, as the correct fill level depends on how much the mixture is expected to rise.

Use cases or prepare the cups as instructed, avoid scratching the surface and allow the muffins to cool slightly before lifting them out.
