Why You’ll Love This Recipe

This vegan royal icing recipe is a game-changer for anyone who wants to enjoy beautifully decorated baked goods without using animal products. It’s quick to make, uses common ingredients, and holds up perfectly once dried.

Here’s why this recipe stands out:

  • Egg-Free & Allergy-Friendly: No raw eggs or egg whites, making it safe for those with egg allergies or vegan diets.
  • Perfect Consistency: Smooth and easy to pipe or spread, drying hard for intricate designs.
  • Customizable: Easily tinted with natural food coloring or flavored with extracts to suit your taste.
  • Long-Lasting: Keeps well when stored in an airtight container, so you can prepare in advance.

Ingredients

  • 1 cup powdered sugar (also known as confectioners’ sugar or icing sugar)
  • 2 tablespoons aquafaba (the liquid from a can of chickpeas)
  • 1/2 teaspoon vanilla extract (optional, for flavor)
  • 1/4 teaspoon cream of tartar (helps stabilize the icing)
  • 1 teaspoon lemon juice (adds brightness and helps set the icing)

Equipment

  • Mixing bowl (medium size)
  • Electric hand mixer or stand mixer with whisk attachment
  • Sifter (to sift powdered sugar)
  • Measuring cups and spoons
  • Rubber spatula (for scraping sides)
  • Piping bags and tips (optional, for decorating)
  • Container with airtight lid (for storing leftover icing)

Instructions

  1. Sift the powdered sugar into your mixing bowl to remove any lumps. This step ensures your icing will be silky smooth.
  2. Whip the aquafaba using an electric mixer on medium-high speed until it forms soft peaks, about 2-3 minutes. This mimics the function of egg whites.
  3. Add cream of tartar and continue whipping for another minute. The cream of tartar stabilizes the aquafaba, helping the icing hold its shape.
  4. Reduce speed to low and gradually add the sifted powdered sugar, about 1/4 cup at a time, mixing between additions until fully incorporated.
  5. Add vanilla extract and lemon juice and beat on medium speed until the icing is glossy and forms stiff peaks. This usually takes 4-5 minutes.
  6. Check the consistency: For outlining cookies, your icing should hold a stiff peak and not run. For flooding (filling in areas), thin it with a few drops of water until it flows smoothly but is not too runny.
  7. Use immediately or cover tightly with plastic wrap pressed directly onto the surface to prevent drying out.

Tips & Variations

“Always cover your vegan royal icing well when not in use to keep it from drying out and cracking.”

  • Coloring: Use natural food colorings such as beet juice powder, spirulina, or turmeric for vibrant and healthy hues without artificial dyes.
  • Flavor twists: Try adding almond extract, peppermint, or citrus zest for unique flavors.
  • Storage: Store leftover icing in an airtight container in the fridge for up to 3 days. Whisk again before use.
  • Consistency adjustments: Add powdered sugar to thicken or a few drops of aquafaba to thin the icing as needed for different decorating techniques.
  • Aquafaba alternatives: If you don’t have chickpea liquid on hand, try aquafaba from white beans, though chickpea aquafaba tends to whip best.
