Ridiculously Easy Royal Icing Recipe For Sugar Cookies

Add confectioners sugar to a mixing bowl or to the bowl of your stand mixer fitted with the wire whisk attachment.

Start mixing on low, and slowly add the milk, corn syrup, and vanilla extract. Continue to whip on medium until smooth.

If the royal icing is too thick, thin it out by misting it with a spray bottle of water, one spritz at a time, until it reaches the proper consistency. If it's too thin, add additional confectioners' sugar a teaspoonful at a time, until it reaches the proper consistency.
