Why Make This Recipe

• Quick and simple: This royal icing comes together in just 10 minutes with a few easy-to-find ingredients.
• Easy to customize: Adjust the amount of warm water to create the consistency you need.
• Perfect for decorating: Use it for cookie outlines, filled designs, lettering, and decorative details.
• Color-friendly: Add food coloring to match holidays, parties, birthdays, or special events.

Ingredients

• 4 cups Powdered Sugar
• 5 tablespoons Meringue Powder
• Up to 1/2 cup Warm Water

How to Make It

1. Mix the powdered sugar with the meringue powder in a mixing bowl. Stir the dry ingredients together until they are evenly combined and free of visible lumps.

2. Add warm water, a tablespoon at a time until you have the consistency of Royal Icing that you desire. Mix well after each addition. Add water gradually so you can control the thickness and avoid making the icing too thin.

3. Add food coloring and mix until combined. Continue mixing until the color is evenly distributed throughout the icing.

How to Serve It

• Use the icing to decorate sugar cookies, gingerbread cookies, or shortbread cookies.
• Pipe it onto cupcakes, cakes, and other baked goods for colorful borders, lettering, or small decorative details.
• Spoon or pipe the icing into a piping bag and use different colors for festive designs and special occasions.

How to Store It

Store leftover royal icing in an airtight container in the refrigerator. Press plastic wrap directly against the surface of the icing before sealing the container to help prevent it from drying out.

When you are ready to use it, allow the icing to soften and stir it thoroughly. If needed, adjust the consistency with a small amount of warm water. Royal icing is not typically reheated, so avoid heating it directly, as heat can affect its texture and appearance.

Helpful Tips

1. Add the warm water gradually. It is easier to thin royal icing than to correct icing that has become too watery.
2. Keep the bowl covered when you are not mixing or decorating, because royal icing can form a crust when exposed to air.
3. Mix food coloring in thoroughly for an even shade, then check the consistency again before decorating.

Optional Variations

• Divide the icing into separate portions and add different food coloring to each portion for multicolored decorations.
• Use gel food coloring for bold shades while adding minimal extra moisture to the icing.
• Create a softer or firmer icing consistency by adjusting the amount of warm water to suit outlining, flooding, or detailed piping.
