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.

    Does this harden up after drying so the cookies can be boxed up/stacked without ruining them? I usually use royal icing to decorate but I’d prefer a meringue free option if it will harden.

      It really will depend on your particular environment and how thick you add the icing. The dryer your weather, the faster it will dry, but for me in the humid south, it takes longer on those really humid or rainy days. I hope that makes sense.

    Hi, I just found your blog and love the recipes! Is it okay to make this ahead or will it harden overnight? I’m hosting a holiday party at my daughter’s kindergarten and wonder if I could make this the night before since we’re setting up during class. Thanks!

    Wanted to use this icing for our upcoming cookie decorating party for the kiddies. How would you recommend storing and dispensing of this icing? Is it liquidy enough that it can be in squirt bottles? Or should it be in a bowl with plastic knives for applying? The kids are ages 3-5yrs, and while I suspect they will be eaten before leaving our house, I don’t want the icing to be super runny Thanks!

      It works great in squirt bottles. That’s how we generally use it for decorating cookies when my son was smaller or when we use when making gingerbread houses, etc. I hope you enjoy it!
