Step 2: Boil Water and Add Soap Shavings

Bring a pot of water to boil on the stove. Once the water is boiling, place a heatproof bowl on top of the pot to create a double boiler. Add your soap shavings to the bowl and a small amount of water. Stir until the soap has become a liquid.

Step 4: Line Muffin Tin 

Grab your muffin tin and line it with paper or foil liners. This recipe makes four soaps.

Step 5: Pour Soap Mixture Into Tin

Sprinkle additional coffee grounds into each liner so that there’s a thin layer across the bottom. Then, using a spoon or ladle, fill each liner with your soap mixture until nearly full.
