This way, you have everything ready to go. Enjoy the process of making your icing. It’s a fun way to express your creativity through food! {{ingredient_image_2}} - Start by sifting 4 cups of powdered sugar. This step is key. Sifting removes lumps and makes smooth icing. If you use meringue powder, mix it with 1/2 cup of water until dissolved. This creates a good base for your icing. - In a large mixing bowl, add the sifted powdered sugar and 3 large egg whites (or the meringue mix). Begin blending on low speed. This prevents a sugar cloud from forming. - After a minute, raise the mixer speed to medium-high. Beat for about 5 to 7 minutes. Look for stiff peaks. To test, dip a spatula into the icing. It should hold its shape and stand tall without drooping. - Now, gently fold in 1/2 teaspoon of fresh lemon juice and 1 teaspoon of vanilla extract. Mix for another minute.

There are two main ways to decorate with royal icing: flooding and outlining. Outlining uses thicker icing to create a border. This holds the flooding icing inside. Flooding fills the space inside the outline. Each method adds depth to your design. Allow drying time between each layer. Let the outline dry before flooding. This will help keep the colors separate and clean. Enjoy the process and have fun experimenting! Pro Tips Use Room Temperature Ingredients: Ensure your egg whites are at room temperature for better volume and stability in your icing. Test Icing Consistency: When adjusting the icing, remember the 10-second rule: it should take about 10 seconds for a line drawn through the icing to disappear. Color Mixing Tips: Start with a small amount of food coloring and gradually add more until you achieve your desired shade to avoid over-saturation. Use Piping Bags for Precision: For intricate designs, use piping bags with different sized tips to control the flow of icing accurately. {{image_4}} You can make royal icing without eggs.

Magical Royal Icing for Sugar Cookies

A delightful icing perfect for decorating sugar cookies with a glossy finish.
Print Recipe Pin Recipe
Prep Time 15 minutes
Total Time 15 minutes
Course Dessert
Cuisine American
Servings 24

Ingredients
  

  • 4 cups powdered sugar
  • 3 large egg whites
  • 0.25 cups meringue powder
  • 0.5 cups water
  • 1 teaspoon vanilla extract
  • 0.5 teaspoon fresh lemon juice
  • as needed food coloring

Instructions
 

  • In a large mixing bowl, start by sifting the powdered sugar to ensure there are no lumps. If you're using meringue powder instead of egg whites, mix the meringue powder with the water in a separate bowl until dissolved before adding it to the powdered sugar.
  • Using a hand mixer or a stand mixer fitted with a whisk attachment, begin to mix the powdered sugar and egg whites (or meringue mix) on low speed. This initial blending is crucial to avoiding a powdered sugar cloud!
  • Once well combined, gradually increase the mixer speed to medium-high. Continue beating for approximately 5-7 minutes until the icing reaches stiff peaks. To test for the right consistency, dip a spatula into the icing; it should hold its shape and stand upright without drooping.
  • Now, gently fold in the lemon juice and vanilla extract (if using) and mix for an additional minute, ensuring these flavors are fully incorporated into the icing.
  • If you're adding color, pour the icing into small bowls and add food coloring. Mix in the color until you achieve your desired shade; remember, you can always add more color if needed!
  • Adjust the icing consistency if necessary. If it's too thick, add a few drops of water to thin it down. Conversely, if it's too thin, gradually mix in more powdered sugar until it reaches the optimal consistency for either flooding or outlining your cookies.
  • Decorate your sugar cookies with the royal icing, taking care to allow sufficient drying time between flooding and outlining if utilizing both techniques for more intricate designs.

Notes

Consider letting the decorated cookies sit for a few hours to allow the icing to set, creating a beautifully glossy finish. Arrange them on a decorative platter for a stunning display!
