It works great for spreading or piping onto cookies, whichever you prefer. You can also easily make the cookie icing thinner or thicker based on your preferences. You’ll add a little bit more sugar for it to be thicker and a little more milk for it to be thinner. Totally up to you to get the cookie icing to the consistency you prefer.

    Thank you – perfect for valentines cookies! I left the cookies out overnight to allow the icing to harden (shortbread, no cookies were harmed!). I halved the recipe and went ahead with coloured vanilla because I added red food colouring.

  2. Hi I was wondering what you think the break down would be for icing for a single cookie? I am doing cookie party with students but i want them to mix there ingredients independently. Thank you

    Thank you for sharing your recipes with us. I enjoyed your chewy sugar cookies and your family cookie icing recipe. However, I added two tablespoons of melted unsalted butter to the recipe. Years ago (several!) I had a Land of Lakes pamphlet and they had a cookie icing recipe like yours but it included the melted butter. I also periodically add almond or orange extract to the icing recipe too.

  4. Dear  Robyn,
    It is my first time making royal icing for sugar cookies.  I have 15 medium size olaf cookies to decorate for grandson’s birthday.  How long will the icing last if made ahead of time.  I was making it with milk.   And is it necessary to keep in refrigerator.  I would perfer not. Thank you . Carolyn

    1. Hi Carolyn,
      I just want to make sure you know that my Cookie Icing is not quite the same as a royal icing. My icing has more of a glaze consistency than the royal icing.
      You should not have to refrigerate my icing. It should stay fresh in an airtight container for up to a week.
      As with any special event, when making a recipe for the first time, I always suggest giving it a test run before the big day. I hope this helps!
      I hope your grandson has a happy birthday! Thanks! xo

  5. Hi Robyn,

    Just a question, can I make this with anything other than cows milk?
    Would nut milks work? Or even water in a pinch?
    I’m making cookies with a group of work colleagues so just want to provide alternatives if possible.
