Finally I found a great dairy free frosting that holds it's shape for decorating and tastes great too! Yeah for that!
Easy "Butter"-cream Frosting
1 cup dairy free butter/margarine, softened to room temperature
3 1/2 cups powdered sugar
1 tsp almond milk, vanilla (but regular works too)
1 tsp vanilla
In a mixing bowl or your stand-up mixer cream the butter/shortening. Add the powdered sugar a little at a time. Lastly add in the almond milk, vanilla and salt and mix until nice and smooth. (I don't recommend refrigerating this frosting before using it. If you do need to refrigerate it, you will need to let it come to room temperature before being able to spread it ;)
