RECIPE: Pumpkin Spice Latte Cupcake Soap

I have taken a lot of classes through The Nova Studio.  One of the classes was a cold process soap class on how to make Cupcake Soaps.  I have not tried to make them yet since I only tried to make cold process soap earlier this year.  I saw this project from Wholesale Supplies Plus called Pumpkin Spice Latte Cupcake Soap.  This is an advanced project (indicating...danger chemicals) that uses pumpkin seed butte and pumpkin flakes.  I normally use Sodium Hydroxide Beads but this recipe uses flakes.  So I do not know if subbing one for the other would work.
