Preheat oven to 350°F. Using a small amount of the butter, butter two ramekins or 2 cup baking bowls. Then split the remaining butter between prepared bowls.
Place one ramekin in the microwave for about 30 seconds on high to melt butter. Repeat with other.
Drop two whole eggs into each bowl. Top each with 1 tablespoon of grated cheese.
Bake in oven for 15 minutes or until egg whites become white.

Notes
The butter can be reduced to just enough for greasing the cups if not egg fasting. To air fry, cook at 325°F for about 12 minutes.
