Ingredients
Scale
Dry Ingredients
- 4 cups (480g) confectioners’ sugar, sifted
- 1/2 cup (60g) meringue powder
Wet Ingredients
- 1/2 cup (120ml) warm water
- 2–4 tablespoons (30-60ml) extra warm water, for adjusting consistency
- 1 teaspoon (5ml) clear vanilla extract
- 1 tablespoon (15ml) light corn syrup (Optional but Recommended)
Instructions
- Sift the confectioners’ sugar: Sift the 4 cups of confectioners’ sugar into a large mixing bowl to eliminate lumps and ensure the smoothest base for your royal icing.
- Combine dry ingredients: Add 1/2 cup of meringue powder to the sifted sugar and whisk briefly to thoroughly mix these dry ingredients together.
- Add warm water: Gradually pour in 1/2 cup of warm water while stirring continuously with a spoon or spatula until a smooth, paste-like mixture forms with no dissolved powders remaining, which is essential for a crack-free finish.
- Incorporate flavor and sheen: Stir in 1 teaspoon of clear vanilla extract and 1 tablespoon of light corn syrup. The corn syrup adds a subtle gloss and prevents the icing from becoming brittle.
- Beat the mixture: Using an electric mixer (stand mixer with paddle attachment or hand mixer), beat on medium-high speed for 5 to 7 minutes until the icing turns bright white, shiny, and holds stiff peaks when the beaters are lifted. Avoid over-mixing to prevent brittleness.
- Adjust consistency: Add the extra warm water slowly, one tablespoon at a time, until you achieve the desired texture: firm enough to hold shape for piping, or soft enough to flood and spread smoothly without running off the edges of your cookies.
Notes
- Sifting the sugar is key to preventing lumps and grit in your icing.
- Use warm water to help dissolve the meringue powder properly for a smoother finish.
- Light corn syrup is optional but improves sheen and texture.
- Do not overbeat, as too much air can make the icing brittle once dried.
- Adjust consistency carefully by adding water gradually for either piping or flooding purposes.
- Store unused royal icing in an airtight container to prevent it from drying out.
