re: My Bakery's Buttercream Icing - great for cupcakes!

Good Morning! I am loving your blog!! I do have a ?. Your Bakery’s Buttercream Icing calls for 1 pkg powdered whipped topping mix. I am not sure what that is. I hope this doesn’t sound stupid. :) Thank you for all of your wonderful recipes, instructions & blog! I am just beginning to ‘get into’ making cupcakes & cakes! Thank you very much!
