1. Add 1 lb. of cut up white soap to microwavable mixing bowl. Heat in microwave in 30 second increments until completely melted. 
  2. Add Foaming Bath Whip and gently stir.
  3. Heat glycerin and myristyl myristate in measuring cup until completely melted.
  4. Whip soap mixture and slowly add glycerin mixture while continuing to whip.
  5. Whip entire mixture, scraping sides occasionally with spatula. 
  6. Once product starts to thicken slightly, add fragrance oil and blend until incorporated.
  7. When frosting just starts to thicken enough to hold its shape, turn off mixer. If necessary, place in fridge for 10-15 minutes to cool and thicken. 
  8. Using a pastry bag with desired decorating tip added to it, fill with soap frosting and decorate the top of each soap cupcake. If desired, add sprinkles, glitter, etc. at this time.
  9. Let product sit for about 24 hours to completely harden. Your soap will then be ready to package.
  10. Should your frosting start to harden up a bit before you have finished piping, reheat and whip slightly with hand mixer to soften it.
  11. NOTE: To color your frosting, add small amount of liquid dye after adding fragrance. Liquid dye can thin out product if too much is used. Powder dyes can also be used.
