Spread butter on both sides of a piece of bread.

Use a round biscuit cutter to cut a hole out of the center of the bread.

Place the slice of bread and the cut-out in a skillet. Allow the bread to toast.

Flip the bread slice and the cut-out, and add butter to the pan in the hole of the bread slice.

When the butter is melted, crack the egg into the hole.

Cover the pan.

Cook until the egg white is completely opaque.

Serve and enjoy!
