This last Christmas I decided to try my hand at making lots of Christmas cookies to give away as gifts. And after reading a little bit about royal icing on one of my favorite food blogs, I was more than motivated to see if it was something I could get the hang of! In the end, I think I cheated a little bit, but I absolutely loved the result. The main idea with royal icing is you use a thicker batch to edge your cookie, then a thinner batch to fill in the rest. It dries smooth and hard, with just a slight sheen to it. I certainly haven’t seen anything prettier (especially the pictures on the tutorial I’ll link to below). I went the easier route and just traced snowflake lines, also due to the fact that I don’t love icing.
- 4 cups powdered sugar, sifted
- 2 tbsp. meringue powder (you can get this from Joann’s or Wiltons)
- 5 tbsp. water
Combine all ingredients in the bowl of a stand mixer fitted with the paddle attachment. Mix on low speed until the sheen has disappeared and the icing has a matte appearance (about 7-10 minutes). Transfer the contents of the mixing bowl to an air-tight container. This will be the stiffest consistency of the icing, and at this point it is still too stiff to use for decorating. Add water a very small amount at a time and stir by hand until fully incorporated. Continue until the icing has reached a consistency appropriate for piping. (Remember, if you are having any difficulty piping, it is still too thick. Add a little more liquid and try again.) Using a pastry bag, pipe around the edges of each cookie. Let stand so the icing will set. Make sure to keep the leftover icing covered at all times when not in use so that it does not begin to harden.
Once all the cookies have been edged, transfer some of the remaining icing to a separate air-tight container. Thin out by incorporating a small amount of water at a time, until the icing drips off the spoon easily when lifted and then smooths in with that still in the bowl. If you go too far and the icing is too thin, add more sifted powdered sugar to thicken it again. Once the icing has reached the desired consistency, transfer it to a squeeze bottle (or a plastic bag with a hole in one corner), and flood the area surrounded by the piping on each cookie. If it does not completely spread to the edges, use a toothpick to help it along. Allow to set.
Use the remaining thicker icing for piping decoration as desired. Gel icing color is best as it does not add a significant amount of liquid. Liquid food coloring can be used as well – add powdered sugar as needed to compensate for any thinning that occurs.
