Orange Cream Cupcake Soap

Earlier this month, I learned how to make cupcake soap by the cold process method at The Nova Studio, which was a very easy process.  And I have seen a melt and pour kit at Michaels which someone in the cold process class said the frosting just went flat. But I found this melt and pour recipe on how to make Orange Cream Cupcake Soap from Natures Garden Candles.  I wonder if it is adding the glycerin to the soap base that keeps the frosting lofty.  May have to give it a try sometime.
