How to make powdered sugar icing: it’s as easy as 1, 2…!

Yep, there’s actually not a third step to this powdered sugar icing. All you have to do is two easy steps! Here’s what to do (or see the full recipe below):

Mix together powdered sugar and milk. We usually do ½ cup powdered sugar to 1 tablespoon milk. You’ll stir it together for 1 minute, until all the lumps dissolve and it’s a drizzle-able texture. This makes for ¼ cup powdered sugar icing.
Drizzle on cookies or muffins! That’s it! You’ll need to make sure that the cookies or muffins are fully to room temperature, otherwise the icing will melt. And we have an easy trick for drizzling…

The best way to drizzle icing? With a FORK.

You’d think the easiest way to drizzle powdered sugar icing would be with a spoon. But actually, drizzling with a spoon can result in a chunky drizzle. Because you can load quite a bit of icing onto a spoon, it come out really fast and you don’t have great control over the drizzle.

The best way to drizzle icing is using a fork! This gives you the best control and helps you make a perfectly thin lines. Of course, you can also pipe icing using a pastry bag. But this powdered sugar icing is the type meant for drizzling on cookies, muffins, and Bundt cakes: and using a fork is the easiest way to do it!

How to make powdered sugar icing vegan?

You can make this powdered sugar icing vegan as well! Substitute your favorite non-dairy milk for the dairy milk. This includes: almond milk, coconut milk, or oat milk. The important thing to remember is: almond milk especially has a more watery texture than dairy milk. So start with a little less milk than you would with dairy, and add just enough to get it to a drizzle-able consistency.
