Equipment

  • You’ll need:
  • Stand mixer or hand mixer with whisk attachment
  • Large mixing bowl
  • Measuring cups and spoons
  • Rubber spatula
  • Airtight container (for storage)
  • Piping bags and decorating tips

Method
 

step1:
  1. In a large mixing bowl, combine the powdered sugar, meringue powder, and cream of tartar. Whisk briefly to remove lumps and mix evenly.
step2:
  1. Add water and clear vanilla extract to the dry mixture.
step3:
  1. Using a stand mixer fitted with the whisk attachment (or a hand mixer), beat on low speed for 30 seconds, just until the ingredients are combined.
step4:
  1. Increase to medium-high speed and beat for 7–10 minutes until the icing becomes glossy, thick, and holds stiff peaks.
step5:
  1. Check consistency:
  2. For outlining, icing should be thick and hold its shape.
  3. For flooding, thin it with 1 tsp of water at a time until it flows smoothly off a spoon and settles within 10–12 seconds.
step6:
  1. Divide icing into separate bowls if adding food coloring. Use gel colors for rich, vibrant tones.
step7:
  1. Cover icing with plastic wrap directly on the surface to prevent drying, or transfer to airtight containers until ready to use.

Notes

🧊 Storage & Reheating
Store royal icing in an airtight container at room temperature for up to 2 days.
For longer storage, refrigerate for up to 2 weeks or freeze for 2 months.
Before using, bring to room temperature and re-whip briefly to restore texture.

❓ 10 FAQs
1. What is royal icing made of?
It’s a blend of powdered sugar, meringue powder, cream of tartar, and water.
2. Can I use egg whites instead of meringue powder?
Yes — replace 5 tbsp meringue powder and 6 oz water with 2 pasteurized egg whites and 4 cups powdered sugar.
3. How do I make my icing shiny?
Beat until glossy and avoid overmixing; drying in a slightly humid room helps retain shine.
4. Why add cream of tartar?
It stabilizes the meringue and helps icing hold its shape.
5. Can I flavor it?
Yes — use clear vanilla, almond, or lemon extract for custom flavors.
6. How long does royal icing take to dry?
It usually dries in 6–8 hours (or overnight) at room temperature.
7. Can I color royal icing?
Yes! Use gel colors to maintain the icing’s consistency.
8. Why does my icing have air bubbles?
Overmixing or fast beating causes bubbles — let it rest for 10 minutes before using.
9. Can I use royal icing on cakes?
It’s best for cookies, gingerbread, and intricate decorations, not full cake coverage.
10. Why did my icing crack?
It dried too fast — avoid direct sunlight or strong fans during drying time.
