Hmmm, I always think of sugar cookies for Santa. The one's decorated with colored sugar & sprinkles. Are you wanting to blend the milk with the cookie fo? My favorite milk scents are Daystar's Milk Sugar Kisses, and I recently got Lait Sucre in from Scentworks, oob it's perfect but I haven't put it in wax yet. Another one that was on my list to try, KY used to have a Sweet & Creamy that was supposed to smell like sweetened condensed milk but I haven't checked to see if AH/RE carries it. I hths!
