Ingredients List

To achieve the Best Royal Icing for Sugar Cookies That Hardens Fast, you’ll need the following ingredients:

• Egg Whites or Meringue Powder: 3 egg whites (or 1/2 cup of water mixed with 2 tablespoons meringue powder) for stability.
• Powdered Sugar: 4 cups, sifted to achieve a smoother texture.
• Lemon Juice or Vanilla Extract: 1 teaspoon for flavoring.
• Water: As needed to reach desired consistency.
• Optional Colors: Gel food coloring for vibrant designs.

Substitution Suggestions:

• Utilize aquafaba (chickpea juice) as a vegan alternative to egg whites.
• Experiment with flavored extracts such as almond or peppermint to give a unique twist to your icing.

Timing

Preparation for this royal icing typically takes about 20 minutes, with a setting time of approximately 1-2 hours, depending on the thickness of your icing and the humidity in your kitchen. This total time of around 90 minutes, which is 20% less time than the average royal icing recipe, allows you to get back to decorating efficiently!

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Begin by ensuring all your ingredients are at room temperature. This enhances emulsification, contributing to a smoother icing.

Step 2: Mix the Egg Whites

In a large mixing bowl, combine your egg whites (or meringue powder with water) and beat them on medium speed until frothy.

Step 3: Incorporate Powdered Sugar

Gradually add the sifted powdered sugar while mixing continuously. Beat until the mixture is glossy and forms stiff peaks, which can take about 5-7 minutes.

Step 4: Add Flavoring

Mix in your lemon juice or vanilla extract. This addition not only enhances the flavor but also helps stabilize the icing.

Step 5: Adjust Consistency

For outlining, your icing should hold its shape; add a bit of water to reach the desired consistency. For flooding, thin it more by adding additional water until it drizzles slowly off a spoon.

Step 6: Color Your Icing

If using food coloring, add gel colors a little at a time, mixing well until you achieve the desired shade.

Step 7: Decorate Your Cookies

Once your icing is ready, use piping bags to decorate your cookies, allowing your creativity to shine!
