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. Here’s my family’s cookie icing recipe perfect for using with our sugar cookie recipe that I’ll share tomorrow. You definitely don’t want to miss it! Happy Cookie Making! XO,Robyn
