Create a double boiler by filling the small saucepan with one cup water, topping with the metal or glass bowl, and placing over medium heat. Now add the soap to the bowl and let it melt completely with the help of the steam from the boiling water below, which only takes a couple of minutes.
While the soap is melting, lightly grease four rounds of a muffin tin and place a small spoonful of coffee grounds at the base of each. Once the soap has become liquid, turn off the heat, add the vanilla, and add one teaspoon of the coffee grounds. You can also add the powdered milk and give things a stir.
Now carefully ladle the soap into the muffin tin, filling to the top of each round. Allow the soaps to cool for several hours, and then pop them out with the help of a butter knife. Wrap in parchment paper and give to your favorite guy.
The homemade soap cleans with a java-infused lather, but remind your guy to keep his soap on a soap dish or tray to prevent unwanted coffee stains.
Along with making homemade soap, here are a few more uses for used coffee grounds.
