Hi Bold Bakers!
While I’m not a pro cake decorator, I have all the tricks up my sleeve to make you think I might be! My recipe and method for making Easy Royal Icing for Cake Decorating is one of my go-to for making cake decorating easy as can be. Made with only 3 ingredients, royal icing is a classic for a reason— it’s simple to make, easy to use, and is the first step in making a cake (be it a Christmas Cake or otherwise!) beautiful.
What is Royal Icing?
Royal icing is made of egg whites, powdered sugar, and a dash of lemon juice. This ratio of egg white-to-powdered sugar, when whipped to perfection, transforms into a light, fluffy, and very sturdy icing. This frosting can even be used as a glue to decorate gingerbread houses and cakes like my Irish Christmas Cake.
How to Heat Treat Egg Whites
While this step is NOT necessary to making royal icing, it’s a good method to know when working with raw egg whites in case you’re worried. To heat treat the eggs, cook them in a bain-marie over low heat for 2-3 minutes, whisking constantly. Do this just until the egg whites have become warm — but are not hot. This will kill any potential bacteria in the eggs, making them safe to use when raw, and with the addition of the lemon juice, you’ll be as safe as can be! IF you don’t want to use egg whites at all then you can use meringue powder to make this frosting also.
Cake Decorating with Royal Icing
I love to use this thicker form of royal icing to smooth over cakes and create a blank snowy slate for other decorations. Additionally, my easy royal icing is the perfect consistency for creating a really fun texture. To do this, I get creative with an offset spatula and go to town, creating lovely swirls and peaks.
How Long Does it Take for Royal Icing to Dry?
Royal icing will begin to set after one hour, forming a nice skin. After 4-6 hours, the icing will harden completely — holding whatever form you give it while decorating.
How long does royal icing last?
Before using royal icing, keep it covered tightly at room temperature (cling wrap works wonders, just make sure it’s touching the surface). Once used and dried, royal icing will remain intact for up to one month preserving all of your beautiful decorations.
