If you are just using some cheese and some eggs, make sure they are out and ready at your workstation.
Next, sprinkle some cheese on the bottom of each stuffing cup. Add one egg to each muffin cup. Bake for about 20 minutes. Remove from oven and sprinkle with cheese, if desired. Return to oven for another 5 minutes.
Add a pinch of cheese to the bottom of each cup. Then, crack an egg into each cup. Bake for about 20 minutes, remove from oven and add some cheese if desired and return to oven for about another 5 minutes or eggs are done to your liking. If you used scrambled eggs, use a toothpick to confirm that the eggs are done. The toothpick should come out clean if eggs are cooked. The scrambled eggs will also form a sort of dome that looks cooked at the top, in the middle, when they are done.
