The easiest icing
The great thing about an icing like this is there is no one recipe, no single way to make it. It is essentially powdered sugar and a liquid. That liquid can be whatever you’d like it to be, whatever goes with your recipe— lemon juice, liqueur, or in this case, maple syrup. Water and milk are also traditional choices that I use a lot.
Simply whisk together 1 cup powdered sugar and 1 tablespoon of your chosen liquid. While whisking, add an additional 1-2 tablespoons of liquid until you reach your desired consistency. If you end up with an icing that’s too liquidy, simply add more powdered sugar. If it’s too stiff, add more liquid. Drizzle it over your baked good and let it sit for 10 minutes to firm up.
