Hi there, I have been reading all of the above info on making icing and using the meringue powder and sugar. I will be using my icing for my dog treats and wanted to know if there is something other than sugar that I could substitute to mix withthe meringue. Thank you for your time and information. P.S. I use King Arthur wheat flour in my dog treat recipies. I'd say it's time to check with your vet. Just print off a copy of the Royal Icing recipe and bring it in with you and see if he/she feels it would or would not work. Confectioners' sugar is the base of Royal Icing and you can't really make it without the sugar. Good Luck! ~ MaryJane
