Royal icing is a wonderful icing to work with, especially in warm weather. It sets so well, making this my most preferred choice for piping flowers for cake decorating. And its non-greasy texture makes cleaning super quick and easy too!

What is Royal Icing?
Royal icing is a type of frosting made using egg whites and powdered sugar. It is used to not only cover cakes, but also as a decorating medium for cupcakes and cookies. Royal icing can be made in stiff or runny consistency, making it suitable not only to cover cakes and piping decorations but also to cover cookies.
I don't quite know how royal icing got its name, but I always thought its the best description for the icing. In its totally white and silky smooth texture, the icing does indeed carry an aura of grandeur with it.
The thing I like most about this icing is the fact that it is not affected by its surrounding temperature, which means, it does not melt or lose its consistency in heat. I live in a hot and humid climate and having to work with icing that is heat-sensitive is always a problem. And because of this, when it comes to piping flowers, I always prefer this icing to buttercream.
Also, this is one icing that is so easy to wash up. It's absolutely grease-free and that makes it super easy to wash. Having said that, when making the icing, it is absolutely important to make sure there is not even a tiny trace of grease in any of the utensils used, or else the icing will remain runny and not turn out as fluffy as it should be.
Icing Consistency
Another important note about this icing is the ability to change its consistency from stiff to soft and runny. Stiff consistency is necessary for piping work, be it flowers, borders or Lambeth string work. This is the consistency you get in most royal icing recipes including mine on this page.
In its runny consistency, this icing is used for flooding work. Flooding work or also sometimes known as color flow icing is basically the art of using royal icing to create icing plaques in various designs and shapes, including decorating cookies. To make runny royal icing, you simply dilute the stiff icing with warm water. In adding the water, it's always better to add a little at a time, until the icing reaches a consistency where a cut through the icing with the back of a spoon closes back in the count of 10 seconds.
How to Make
Although royal icing has always been traditionally made using egg whites, meringue powder is now the preferred option for many cake decorators. I have the recipes for both versions of the icing here and although I have personally tried both many times successfully, I now only use the recipe that uses meringue powder instead of fresh egg white simply out of convenience.
How to Make Royal Icing with Egg Whites - The Old Fashioned and Traditional Method
Ingredients
- Egg Whites
- Powdered Sugar
- Lemon Juice (Optional)
Making the icing with egg whites:
- Place the egg whites into a clean and grease free bowl. Whisk them until they turn stiff and frothy.
- Sift powdered sugar to break any lumps. Add it to the whisked egg whites, a little at a time until all the sugar is added in. Continue to whisk until stiff peaks form.
- Finally add the lemon juice and continue beating until the lemon juice is well incorporated.
- Use the icing immediately, otherwise, cover it with a damp cloth to prevent crusting. Color the icing as you wish.
How to Make Royal Icing with Meringue Powder - The Quick and Easy Method
Ingredients
- Powdered sugar
- Meringue powder
- Warm water
Making the icing with meringue powder
- Sift the powdered sugar into a dry and grease free bowl.
- Add the meringue powder and mix well.
- Add water into the sugar and meringue powder mix. Whisk the mixture until it becomes fluffy and stiff peaks form.
- Use the icing immediately, otherwise, cover it with a damp cloth to prevent crusting. Color the icing as you wish.
Notes
Does royal icing harden?
- Yes, it does. It is hard in the sense that it will hold its shape (ie you can touch it and it will not smear or smudge) but not so hard that you cannot break it or eat it.
Does royal icing taste good?
- Royal icing is made mostly with sugar and egg whites. It is sweet, almost like eating sugar.
How long does royal icing take to dry?
- When the icing is dry, that means it has set completely and will be able to hold its shape even when touched. It would typically take a few hours to overnight for this icing to set completely and that depends very much on its consistency and the thickness of its application. In its stiff consistency (piping consistency), the icing will set faster as compared to when it is in a runny consistency (color flow icing). That is because the water content in the color flow icing is more than in the pipeable consistency.
- When in the same consistency, the icing would set faster when piped into a thin line as opposed to when it is used to pipe thicker shell borders, for example.
Is lemon juice in royal icing necessary?
- No, it is not. Lemon juice is only optional.
- It is used simply to flavor the icing and gives the icing a delicious lemon taste, similar to lemonade. Adding lemon juice into royal icing is a good idea for those who do not like the icing to taste like sugar.
How long does royal icing last?
- Royal icing is a very lasting icing. Once piped onto cakes, it will set and harden and can last for 3 to 4 weeks (provided the cake inside can also last that long).
- It is also often used to decorate dummy cakes or display cakes made using styrofoam dummies due to its ability to set hard and last for years!
- Before piping or applying onto cakes or cookies, however, the icing should be kept refrigerated in an air-tight container (with a damp towel covering the top of the container before covering it with the lid). This will prevent it from crusting and can last for 2 to 3 days.
- When ready to be used, remove it from the fridge, whisk it up again and use it as usual.
How to store royal icing?
- Royal icing will start to crust and then harden when exposed to dry air. In a mixing bowl, if left uncovered, the sides will crust and will block your piping tip when you use it for piping work.
- To avoid the unused icing from crusting (even while you are using it to decorate cakes or cookies), keep the icing bowl covered with a damp piece of cloth. This will prevent the icing from crusting.
- If you wish to store it longer before piping, keep the icing refrigerated in an air tight container. Before closing the lid, cover the top of the container with a damp cloth. This will prevent the icing from crusting while in the frige.
