How to Make Royal Buttercream Icing

  2. Continue mixing for 5 minutes to create a royal icing.

What Is Meringue Powder? 

Meringue powder is an alternative to beaten egg whites in baking and is made by the pasteurization process. It’s commonly used in recipes that have uncooked eggs as an ingredient. To make meringue powder, egg whites are dried and combined with cornstarch and gum.  

When used in recipes, the cornstarch and gum create an egg white-like consistency when water is added. It’s a perfect substitute for fresh egg whites.

But, you must use vanilla extract or other vanilla flavorings in recipes with meringue powder. Vanilla helps remove the slightly starchy taste produced when water is added to meringue powder. 

With a long shelf life, it can save you from the hassle of running to the grocery store every time you need to bake something. It’s easily available at all the grocery stores and isn’t expensive.

Helpful Tips 

Remember the following tips if you want the best flavor and consistency of royal icing buttercream: 

  • Mix the basic ingredients until they get toothpaste-like piping consistency. Don’t add too much water at the start or you won’t end up with the perfect consistency. Add a little bit of water at a time, mix and then add more if needed. 
  • If you want to add color to your icing, use gel food coloring. If you use liquid or powdered food color, the consistency of the icing will be affected. 
  • Strain your icing through a fine mesh cloth or sieve to remove the lumps from it. 
  • If you don’t have a stand mixer, you can use a hand mixer, it will just take a little longer and a lot more energy on your part.
  • If taking your baked goods with icing outside, be careful with warm weather as this can impact the texture and consistency of your buttercream. The best way to serve something with this homemade buttercream is inside a well-cooled, air-conditioned building.
  • You can use clear vanilla extract if needed.
  • We recommend using a stand mixer with the paddle attachment to get nice and smooth royal icing buttercream frosting without having to use an electric hand mixer. However, if that is all you have, you can use it.
  • If this is your first time making this American buttercream, I recommend sticking to the recipe, then if you feel comfortable making it on your own, you can deviate and try any of the recipe variations that we share below.

Recipe Variations 

Here are some recipe variations for buttercream royal icing that you can try whenever needed: 

Use powdered egg whites – If you don’t have meringue powder or don’t want to use it, you can add powdered egg whites to your icing. The difference between these two is that powered egg whites are simply dried egg whites without adding flavorings. Using raw egg whites is also an option if you need to use something else other than meringue powder.

Add milk instead of water – If you want a more opaque appearance for your icing, replace water with whole milk. The proteins and fats in the whole milk create an opaque appearance. 

Use any extract flavoring – You can use other extracts in this recipe if you don’t want to use vanilla extract. Try almond extract, maple extract, lemon or orange extracts. You can also add a dash of lemon juice for a nice citrus flavor. You can make many different flavors this way.

Make chocolate buttercream- to turn this super fancy and absolutely addictive royal buttercream frosting into a chocolate buttercream, all you have to do is add some cocoa powder to the frosting when you are whipping it.
