8 slices bread
1/4 c. butter
2 1/2 c. shredded cheese
6 eggs, slightly beaten
2 c. milk

Trim crust from bread and spread with butter. Alternate layers of bread and cheese in an 8 inch square baking dish and end with cheese on top. Mix remaining ingredients, pour over layers. Cover, chill 6 hours or overnight. Bake at 325 degrees for 45 minutes. Four slices of cooked, crumbled bacon can be sprinkled on top just before baking. Let stand few minutes. Cut in squares.
