The Nova Studio in April 2013, one of the project we made were cupcake fizzies with frosting. During the class it was mentioned that we could add special ingredients to them and one of them was shea butter. Melanie, the instructor, said we we would have to experiment with the ingredients to see who it would turn out. Well, I found this recipe Heart Cupcake Bath Fizzies from Wholesale Supplies Plus which included shea butter. In this particular recipe it calls for two tablespoons. I do not know if that will be the appropriate amount for Melanie's recipe but in her recipe she had 2 tablespoons of a carrier oil so maybe that would be the same amount I could use of shea butter.
