This Sugar Cookie Icing is buttery sweet and made in minutes. It’s the ideal texture for pouring in swirling designs over your soft sugar cookies or cut-out sugar cookies and hardens just enough to make them stackable for party platters and edible gift giving.
With a melted butter base, this sugar cookie icing (a riff on this recipe from Tieghan of Half Baked Harvest) has a decadently rich flavor that you can’t achieve with the sugar and water glazes that often adorn sugar cookies. It’s so easy to make – just 4 ingredients and there is no need for a mixer. Just combine the icing ingredients in a small saucepan and whisk until silky smooth (Watch the recipe video below to see what I mean!).
It’s easy to customize this icing to the consistency you prefer; if it’s too thick, add a little water; too thin, add more confectioners sugar.
What’s the difference between icing and frosting?
First of all, the terms are debatable (and you can throw ‘glaze’ in there too). Typically, ‘frosting’ is thick, fluffy, and less sweet than icing. It also stays soft and doesn’t stack well so it’s not ideal for party platters (unless you can place them in a single layer) or for edible gift giving. Icing is sweeter than frosting, glossy instead of fluffy, and is often pourable and hardens enough to allow for stacking.
Is cookie icing the same as royal icing?
Royal icing is typically made with beaten raw egg whites, powdered sugar and often a citrus juice like lime or lemon and hardens as it drys. But ‘icing‘ is a broader term that is used to refer to everything from the simplest glacé icing that is just powdered sugar and water, to elaborate buttercream frostings and fondants.
Many icings are too sweet for my taste, but it’s the amount of sugar that determines how much the icing will harden. This sugar cookie icing recipe leans more toward buttery and hardens just enough to make your cookies stackable, but you’ll want to be gentle with them too.
How to Make Sugar Cookie Icing
Step 1: Melt butter in a small saucepan over medium heat. Add remaining icing ingredients (confectioners sugar, water and vanilla) and whisk until smooth and shiny (all sugar has dissolved). Remove from heat and allow to cool slightly.
Step 2: Transfer slightly cooled frosting to small pitcher for drizzling over sugar cookies. Allow frosting to cool and harden on cookies before serving.

Sugar Cookie Icing
- 1/2 cup butter 1 cube, ideally 85% fat European style butter
- 2 cups confectioners sugar 240g
- 2 tablespoons water
- 1 teaspoon real vanilla extract
- Place butter in a small saucepan over medium heat. When butter has melted, whisk in remaining ingredients until very shiny and smooth (sugar has dissolved completely). Remove from heat and allow to cool slightly.
- Check consistency of icing: it should be thin enough to be pourable, but not so thin that it runs off the sides of the sugar cookie. If too thick, whisk in more water a few drops at a time. If too thin, whisk in more sugar until the icing reaches your desired consistency.
- Transfer icing to small pitcher and swirl artfully over cooled sugar cookies. Let icing cool and harden. Serve.
- If your powdered sugar is at all lumpy, be sure to sift / sieve it to remove any lumps before adding to the butter.
- This recipe makes enough for icing about 25, 3-inch round sugar cookies.
