Does anyone know a decorator cookie icing that looks like royal icing and dries hard but is not royal icing?

I love the way that royalicing looks but it tastes just awful. I have tried using fondant powder but that was just glorified powder sugar. I needs a recipe to decorate cookies and I need a icing that dries hard so that cookies can be stacked but also does not dry the cookie itself out. Does anyone know if I decreas the amount of meringue powder in royal icing, will it still work as well?
