Using two spoons, drop small scoops of batter, first around the outside of the egg, building up the outer edge of the muffin and sealing in the egg whites and yolk, and finally over the top to cover the yolk. Be careful not to apply too much pressure while dropping above the yolk or it may break.
Bake in preheated oven for 30 minutes.
Remove from oven and allow to set 5 minutes before removing from pan.
