This Martha Stewart Royal Icing Recipe is a smooth and versatile icing, which includes confectioners’ sugar and either meringue powder or egg whites. It’s a classic, foolproof recipe, ready in just 5 minutes—perfect for decorating cookies, gingerbread houses, and more.
Martha Stewart Royal Icing Recipe Ingredients
- 1 box confectioners’ sugar (1 pound)
- 5 tablespoons meringue powder, or 2 large egg whites

How To Make Martha Stewart Royal Icing Recipe
- Combine dry ingredients: In the bowl of an electric mixer fitted with the paddle attachment, combine the confectioners’ sugar and meringue powder (or egg whites).
- Add water to mix: If using meringue powder, add a scant ½ cup water. If using egg whites, add just enough water to help the mixer combine the ingredients. Start slowly to avoid a runny texture.
- Mix until desired texture: Beat on low speed until the icing holds a ribbon-like trail for about 5 seconds when the paddle is lifted. Add more water a tablespoon at a time if needed to thin the icing.

Recipe Tips
- How to thin royal icing:
Add water one tablespoon at a time to reach piping or flooding consistency. - Can I flavor royal icing?
Yes, use clear extracts like vanilla or almond to keep the icing bright white. - How to store royal icing:
Cover with plastic wrap touching the surface and refrigerate for up to 3 days. - Why use meringue powder?
It’s safer than raw egg whites and more shelf-stable, especially for decorating cookies. - What consistency do I need for piping vs. flooding?
Piping consistency should hold its shape; flooding should smooth out within 10 seconds.
