How to Make Royal Icing

Learn how to make royal icing from pastry chef Katie Rosenhouse in this Howcast video.


Hi, I'm Katie Rosness and today I'm going show you how to make royal icing.

So when you're doing something like Christmas Sugar Cookies where you want this kind of painted, decorated surface, royal icing is the perfect icing for you.

So it's pretty simple. I have confectioner's sugar, also known as powdered sugar, and I'm going to just add a little bit of meringue powder. Alternatively you could use a fresh egg white, but a lot of people get funny about using raw eggs in their icing.

So to avoid that all together, you can get meringue powder in the store. And I'm just going to add a little, little bit to my confectioner's sugar. Per pound, you're going to add 1/4 of a cup of meringue powder per pound of confectioner's sugar. But in this case, I'm starting with a small amount. I'm just going to add a little bit, and just enough water to bring this mixture together.

So what I'm doing is in a bowl I'm stirring with a spoon until all the water soaks into the sugar and meringue powder. We're going to get a really nice, smooth icing.

You could also do this is the mixer but I just find it's easier to do it by hand.

And you keep stirring. Put some muscle into it. And that's it.

So ways to take this in different direction. This is a great thickness for something like a border around a cookie, or even writing on a cookie.

But if you want to cover and paint the whole surface, I would thin this out with a little more water and you can always add food coloring. This is the place to kind of add your green, your red, all your colors and really jazz up your cookies.

So this is how you make royal icing.
