What You Need to Make Royal Icing
- Powdered Sugar – the main ingredient
- Milk – used for thinning and to make the icing richer than just using water
- Corn Syrup – to keep the icing soft underneath the shiny, firm outer layer
- Food Coloring, optional
How to Use
- Dipping – Make icing the consistency of glue. Put in shallow bowl. Dip the flat side of your cookie into icing. Let excess icing drip off. Place cookie on cooling rack or wax paper to set up.
- Piping and Flooding – Divide icing into 2 bowls. Make one a little thicker with powdered sugar. Put icing into pastry bags. Pipe an outline of the thicker icing around the edges of the cookie. Use the thinner icing in a pastry bag to flood, or fill in, the outline.
- Drizzle – Use a pastry bag to drizzle icing on desserts for a quick way to make any dessert look fancy.
Variations
- Almond extract – Add a couple of drops of almond extract for a mild almond flavor. You may need to add a bit more powdered sugar.
- Vanilla extract – Add a teaspoon of vanilla and reduce milk by a teaspoon
- Paint with Food Colors– If you’re an artist, use liquid food coloring and a clean fine-tipped brush to draw flowers, butterflies, or designs on the top of firm icing. Finish by writing someone’s name in fancy lettering with the food coloring for a special, personalized gift. It kind of looks like painted tiles.
- Glitter – Sprinkle icing with edible glitter before it sets.
Overview | How to Make Royal Icing
The full printable recipe is below.
- Combine powdered sugar, milk, and corn syrup in a mixing bowl.
- Mix until ingredients are smooth.
- Add more milk to thin, a teaspoon at a time, if needed.
- Add more powdered sugar to thicken, just a little at a time, if needed.
- Stir in drops of food coloring until desired color is reached.
Tips
- Cover bowl with a wet paper towel when you’re icing cookies to keep a film from forming on the top.
- Periodically check the consistency of the icing as it may thicken while you’re using it. Adjust consistency as needed during the icing process.
How to Store
Royal icing can be stored in the refrigerator for up to a week. Keep it in a bag with as much air removed as possible, or store in an airtight container. Let royal icing come to room temperature before using. Mix a few times and adjust the consistency by adding more milk or powdered sugar.
Freeze royal icing in a bag that has air squeezed out. Let thaw in refrigerator and then come to room temperature before using. Knead the bag or place icing in a bowl and stir until it is completely smooth. Adjust consistency as necessary. Freeze for up to 2 months.
Royal icing is made so that it can smooth itself out and harden rather than be fluffy and soft. Many other frostings are made with butter so they can be fluffy and soft.
This variety of royal icing is intended to have a firm shell, but still be soft so it is more enjoyable to eat than the crunchy varieties. A royal icing that doesn’t have corn syrup would be better for gluing gingerbread houses together.
