Im looking for a sugar cookies glaze?

Im looking for a recipe for a glaze that I can dip or pour over my sugar cookies to make a semi hard surface that I then can pipe frosting on for more details. The one I have works well but doesn’t taste very good. Who wants a cookie that’s pretty but has a bad flavor. Open to any ideas, recipes and suggestions. Even a regular frosting recipe that gets hard. I’m getting ready to make Easter cookies on Saturday and need help. Thank you!
