This royal icing recipe, perfected over twenty years by a dentist who builds elaborate gingerbread landmarks, dries hard as cement but pipes smooth as buttercream. It’s the reliable, forgiving icing you’ll come back to every December.

Ingredients

Scale
  • 4 cups powdered sugar, sifted
  • 3 tablespoons meringue powder
  • 1/2 teaspoon cream of tartar
  • 1/2 cup warm water
  • 1 teaspoon clear vanilla extract
  • Gel food coloring (optional)
  • Piping bags
  • Couplers and tips (Wilton #2, #4, #12)

Instructions

  1. Sift the powdered sugar into a large mixing bowl.
  2. Add the meringue powder and cream of tartar to the sifted sugar. Whisk together dry to distribute evenly.
  3. Pour in the warm water and vanilla extract. Start mixing on low speed to avoid a sugar cloud.
  4. Mix on medium speed for 4-5 minutes until stiff peaks form—when you lift the mixer paddle, the icing should form a peak that holds its shape without drooping.
  5. Stop and scrape down the bowl at the 2-minute mark.
  6. Test the consistency: Dip a toothpick into the icing. It should stand straight up without falling over. If too stiff, add water one drop at a time. If too thin, add sifted powdered sugar one tablespoon at a time.
  7. Color your icing: Divide into separate bowls and add gel food coloring one drop at a time. Mix thoroughly.
  8. Transfer to piping bags: Fit bags with couplers and tips. Fill halfway, twist the top closed, and secure with a rubber band or twist tie.
  9. Let it rest for 5 minutes to allow air bubbles to rise. Pop any bubbles with a toothpick.
  10. Start piping: Hold the bag at a 45-degree angle and apply steady pressure. Practice on parchment paper first if needed.

Notes

For gingerbread house assembly, use a thicker consistency (stiff peaks) for walls and roof. For decorating, thin slightly with a few drops of water until it flows like honey but holds its shape (flood consistency). Keep bowl covered with a damp paper towel between uses to prevent drying. Icing can be made ahead and stored in an airtight container at room temperature for 3-4 days, in the fridge for up to a week, or frozen for up to 3 months.
