This is all you will need! You can add cheese, ham, sausage or anything you like!
Cook bacon in a large skillet until almost crisp, about 4 minutes.
Lightly butter 6 cups.
Flatten bread slices with your hands and cut 8 rounds of 4 inches. Then cut each round in half.
Press two halves into cups and patch gaps with the extra bread. Lay bacon slices into each cup.
Crack an egg over each cup.
Bake for 20 minutes at 350 degrees or until egg whites are set.
Add salt and pepper and enjoy!
