You can use a shortening-based or margarine-based icing.
Here's the recipe I use for what I call decorators icing
2 cups crisco
4 tablespoons water
2 teaspoons of your favorite flavoring (butter, vanilla, almond, lemon etc)
mix then add slowly 2 pounds of powdered sugar you may need to add more water as you go
You can replace to taste the water with the flavored non-dairy coffee creamers
Hope this helps!
