Just have to say that I tried this recipe that Melissa posted a while back and the cookies are really good! I have a pretty good recipe for frosting also that is IBS-Friendly:
2 cups of confectioner's sugar 3 tablespoons of soy milk 1 teaspoon of vanilla 1 tablespoon of melted soy margarine
Mix the sugar, vanilla, and soy milk together first. Then add the melted margarine. Mix together. It will seem a bit soupy but will start to thicken as you use it. Make sure to use it soon or it will get too hard. Add your sprinkles or decorations before the frosting hardens. I had a good helper with this! My son! I think there is more sprinkles on the cookies than frosting!
