Tutorial: Cookie Decorating with Glace Icing

I consider myself to be a pretty good artist.  My education and former profession is in the design field and I’m pretty good at craft stuff.  I also think I’m a decent cook, so I figured with those two things going for me, decorating fancy sugar cookies would be right up my alley.  Imagine my surprise (not to mention shattered ego and broken self-confidence) when I attempted to play around with royal icing for the first time and my little masterpieces looked more like something in a 1st grader’s art pile.  So I gave up on ever decorating fancy-schmancy cookies again.

That was until I met THIS style of icing. Now my confidence is back in tact because even my very first batch turned out beautifully! It’s super forgiving, easy to use, and it actually tastes good!

The benefit of using an icing like this is that it dries to a solid sheen, making the cookies stackable and packable- perfect for giving or displaying on a platter. With a soft, fluffy buttercream, there’s just no easy way to give them away so you have to eat them all yourself (which may be the plan, right??)

All you need for this icing is powdered sugar, milk, corn syrup, and extract of your choice (I use almond, but vanilla is great, too.)  And we all know that corn syrup is not the same thing as high-fructose corn syrup, right??  Like, we don’t have to have this conversation again?  Okie-dokie then.

Whisk up those few ingredients and you’ll have a nice glaze-y consistency. You’re going to use the same recipe for both glazing and piping. The way it is right now is the consistency you want for glazing. It’s smooth and thin and it easily runs off the whisk in a pretty thin drizzle.

You can simply spoon this icing onto your cookies and gently spread out with a spoon and be done!  One of the easiest ways is also to just quickly spread and let it go completely off the edges like this:

While the icing is wet, you can mix colors and create all kinds of fun things.  Try glazing in one color and then adding other colors from a piping bag with a very small, plain opening, and drag the designs with a toothpick to create gorgeous works of art.

Another method is to pipe an edge around your cookie, and then wait for a few minutes for it to firm up.  When you’re piping, you’ll want to add a bit more powdered sugar to thicken up the icing just a bit.

Wet-on-wet icing will marble and swirl together.  I actually did this whole batch this way because I didn’t have time to let mine dry very much.

If you want to pipe designs on top of your cookies, you’ll want to wait until your first glazing layer is dry to the touch, which can take a couple of hours.  You’ll want to leave them out un-covered to dry.    You can see a great example of this method in this post, where I made darling little Owl Cookies.

Either way, you’ll want to let these cookies dry all the way before stacking or handling too much.

They develop a sheen and are dry to the touch after a couple hours, but they’ll need to really dry for most of the day, or overnight to be completely dry.

Note: Make-Ahead Storage: Thanks so much to a reader who reported back with these notes! Made the glace icing 4-5 days ahead of time, stored it in the fridge, airtight, either wrapped in a pastry bag or in a plastic container with wax paper on the surface. It worked perfectly, did not even need to be re-whisked and barely even had to come to room temperature. Definitely can be made ahead and refrigerated, loved it!” So there you have it – thanks to Kim.

Description

These sugar cookies are as delicious as they are beautiful! Such a fun way to decorate sugar cookies!


Ingredients

  • 1 pound powdered sugar (about 3 3/4 cups)
  • 1/4 cup + 2 tablespoons milk
  • 1/4 cup + 2 tablespoons light corn syrup
  • 1 teaspoon extract (I use almond because I use almond in my sugar cookies, but other flavors like vanilla, lemon, and peppermint are also delicious)

Instructions

  1. With a whisk, combine sugar and milk until smooth (no lumps!) Then stir in corn syrup and extract.
  2. You will use this same recipe for both glazing and piping. Thickened, you can pipe outlines, and as you thin it, you can use it for “flooding” cookies. Make sure to let them dry overnight to fully harden for stacking.

  1. Hit Alt+130 for an é. (The numbers on the side of the keyboard.) Unless you have a laptop, in which case I don’t know how to help you, lol.

    Those look beautiful! Great job! I can’t wait for your sugar cookie recipe because those are the only cookies Diego can eat. Well, unless your recipe calls for eggs and milk. All the sugar cookie recipes I’ve ever tried taste like sand.

    Happy Birthday, Kate!
