We use our dog treat icings and frosting every day, when it's hot, cold and rainy.... And we have some of the highest humidity climates... where moisture can cause icing to become a bit soft again.... SO we created a NEW icing and call it "Rockin' Hard Icing"! Hard as a rock... It is!!! Not only does it stand up to high humidity but it even stays hard in the refrigerator. It is a treat and cake shippers dream... whew, just in time for the hot days of summer. :) The icing does not dry as smooth as the original Treaty Treat Icing but, it is..... fabulous! Remember frosting is for cakes and icing is for treats. Happy decorating!
