2 Muffin Tins with 6 muffin holders each
Brown butcher paper
Making cupcake soap is fun and relatively easy. A piece of cake, as it were. It's a great way to recycle bits of bar soap, such as Ivory, and you can make the cupcake soaps less drying to your skin by adding glycerin. Here is how to make cupcake soap.
Add 3/4 cups water to soap pieces or slivers, or the cut up pieces of 3 bars of Ivory soap, to your microwave safe measuring bowl. Put it in the microwave for 2 minute increments. If it starts to get puffy stop the microwave and stir the mixture. Continue doing this until the mixture is creamy. Add more water and a small amount of olive oil if the mixture seems dry.
Add 5 tablespoons olive oil, 3 tablespoons honey, 3 tablespoons cocoa powder, 3 tablespoons glycerin, 1/2 cup powdered milk, 2 tablespoons ground oatmeal and 3 tablespoons cinnamon to the mixture and stir it. Add extra water and olive oil if the final mixture seems to be too dry still.
Coat your muffin tins with a light coat of olive oil. This is so your soaps will easily pop out when they are finished curing.
Pour the mixture into the muffin holders of both of your muffin tins until they are nearly full leaving about 1/4 of an inch at the top. Allow the soaps to dry in the muffin tins overnight.
For the frosting, add 1/4 cup water and one Ivory soap bar, cut into small pieces, or the equivalent amount of scraps of Ivory soap, and 1 tablespoon glycerin to a clean Pyrex bowl. Heat in the microwave in 2 minute increments as you did with the first batch and add a bit of olive oil or water if it gets dry. Continue until the mixture's consistency is creamy. Add 1 teaspoon iridescent soap glitter and your frosting for your cupcake soaps is ready!
Sprinkle a little sugar on top of each cupcake soap and frost each with the mixture you made in Step 5. The sugar will add a bit of friction to your soaps, and also give them a sweet scent along with the cocoa powder, honey and cinnamon.
Allow the frosted cupcake soaps to sit for two or three hours then remove them from the muffin tins. They are now ready to be used. You can wrap the ones you won't use right away in brown butcher paper and store them. They will keep for a year.
Use ice cube trays if you want to make a different shape of soap. You could also use small round teacups if you didn't have muffin tins.
Add dyes to obtain different colors, or herbs and flavorings for different types of food scents.
Once you've used your muffin tins, microwave-safe bowl, and wooden spoon to make cupcake soaps don't use them for anything else. This is especially important if you should ever want to make soap using lye which is deadly if ingested.
