Using a knife and cutting board, carefully chop the soap into approximately 1/2″ cubes.
Place the soap cubes in a glass container. Melt the cubes in the microwave for 30 seconds. Stir. Continue melting in the microwave in 15-second increments until most of the soap is melted.
Once the soap is fully melted, stir in a few drops of coffee fragrance oil or essential oil if you are using it.
Then stir in the coffee grounds.
Pour the melted soap mixture into your molds and sprinkle a few coffee grounds on top if you would like. Immediately spray isopropyl alcohol on the soap the dissolve any air bubbles.
Allow the soap to harden for approximately 2 hours before removing from the molds.
Wrap the soap in plastic wrap to keep it from attracting moisture from the air.
