Bake muffins on the centre rack of a preheated oven for 20–30 minutes until clean.
Muffins are done when they reach 190°F. For a completely cooked muffin, insert a digital thermometer into the centre and wait until the numbers stop moving.
Optional, but eliminates muffin completion guesswork.Remove the papers when the muffins are room temperature. Peeling paper liners from warm muffins wastes most of the muffin.
