Why dont you make your own butter cream? You can used vegetable gum as opposed to butter so it wont melt, and mix with pure icing sugar and a stabiliser (its like dehydrated egg whites which makes the frosting set slightly. You can use a pavlova egg if you dont have a cake supplies shop handy). You can just add a little vanilla flavour and whatever colours you like. If you want the recipe i use, let me know. Using no dairy means they wont need to be refrigerated. Its an aevantage for me.
