Royal Icing Recipe
Introduction
Royal icing is a smooth, hard-drying icing perfect for decorating cookies and cakes with intricate designs. Made mainly from meringue powder and confectioners’ sugar, it’s easy to prepare and can be colored to suit any occasion.

Ingredients
- 1/4 cup meringue powder
- 4 cups (460 g) confectioners’ sugar
- Food coloring, for decorating
- Water (as needed)
Instructions
- Step 1: In a large bowl, use a handheld mixer on medium-high speed or a stand mixer fitted with a whisk attachment to beat the meringue powder and 5 tablespoons of water until the mixture is frothy and beginning to stiffen.
- Step 2: Add the confectioners’ sugar and beat on medium speed until the icing is smooth and thick. If needed, add additional water one tablespoon at a time until the icing holds its shape but is still workable.
- Step 3: Add your desired food coloring and beat again until the color is fully incorporated.
- Step 4: To thin the icing for flooding cookies, add water one teaspoon at a time until the icing holds its shape briefly when drizzled but then slowly melts into itself.
Tips & Variations
- For stiffer outlines, keep the icing thicker and avoid adding extra water.
- Add a few drops of lemon juice or vanilla extract to enhance flavor.
- Use gel food coloring for more vibrant colors without thinning the icing.
Storage
Store royal icing in an airtight container at room temperature for up to two days. To prevent it from drying out, press plastic wrap directly onto the surface before sealing. If the icing hardens, add a few drops of water and stir to restore the desired consistency before use.

FAQs
Can I use egg whites instead of meringue powder?
Yes, fresh egg whites can be used as a substitute, but be aware of food safety risks and a shorter shelf life. Meringue powder is preferred for convenience and stability.
How do I know if the icing is the right consistency for decorating?
The icing should hold its shape when you pipe it and not run. For flooding cookies, a thinner consistency is ideal—when drizzled, it should keep its shape briefly before leveling out smoothly.

Notes
