I love this Perfect Customizable Royal Icing because it’s easy to make, flavor, and use! Here’s an amazing Foolproof No Chill No Spread Sugar Cookie recipe to use this icing on! Be creative and mix and match your flavors!
Here’s a link to my YouTube video of me making royal icing and chocolate sugar cookies (Live Broadcast!). https://youtu.be/kH5ciAJALEo
Perfect Customizable Royal Icing
Add your vanilla (or other flavoring) to your warm water and set aside.
Using a stand mixer with a paddle attachment or a hand mixer on low, mix your powdered sugar, meringue powder, and cream of tartar together.
With your mixer on low, slowly pour your warm water with your flavoring into the dry ingredients.
As soon as all of the ingredients are incorporated, scrape down the bottom and sides of your bowl.
Turn your mixer to medium-high and beat until the royal icing is white and will hold a stiff peak when the paddle is removed.
This is a fairly thick consistency because that's how I prefer mine. Even when flooding my cookies, I use it thicker than most people. Remember, the thinner the royal icing is, the longer it will take to dry. You can very easily add small amounts of water to thin it out to your preferred consistency.
To store, place into an airtight container. I also put a piece of plastic wrap onto the royal icing to keep it from forming a crust. I prefer to keep mine in the fridge for up to a month (although, it's usually gone within 2 weeks).
For different flavors you can very easily sub out the vanilla for other flavorings and emulsions! I would recommend starting with 1 to 1 1/2 teaspoons instead of a tablespoon as they have different potencies. You can also use spices as flavorings! Again, start with 1 teaspoon because they do go further. When coloring my royal icing I prefer Americolor gels because they are much more pigmented and last much longer!
