Eggless Royal Icing – Perfect for Cakes, Cookies & Decorations

A Modern Twist on a Classic Tradition

    The art of cake decorating has always been an integral part of festive baking. Growing up, we never baked cakes at home, but it was a tradition for my dad to buy beautifully iced Christmas cakes from JM & Sons, a beloved bakery in Coimbatore. These cakes were a special treat, with their firm, sweet royal icing and those charming rose-shaped sugar flowers on top. I adored them—not because they were sugary delights, but because they were roses. My love for flowers started early, and even though adulthood has made me a bit more restrained, those sugar roses will always hold a special place in my heart.

Traditional Vs. Vegan/Eggless Royal Icing

    However, Traditional royal icing relies heavily on egg whites or meringue powder, which often left me searching for a better alternative. After years of experimenting, I finally perfected a Vegan Royal Icing or simply Eggless Royal Icing, in my terms, delivers the same glossy finish and firm set—without eggs, meringue, or any substitutes that mimic them.

    For those who, like me, prefer a simple yet effective recipe, this one is a game-changer. It’s silky, pipeable, and sets beautifully, making it ideal for cakes, cookies, and intricate decorative designs. Plus, there’s no risk of an overpowering eggy taste or raw egg concerns. Whether you're embracing a plant-based lifestyle or just want a fuss-free royal icing, this recipe is a must-try!

Why You’ll Love This Recipe

    Are you tired of royal icing that tastes overwhelmingly eggy? I was too! After countless experiments, I’ve finally nailed the perfect vegan royal icing—one that’s silky, pipeable, and sets beautifully without a single egg or egg substitute like meringue powder in sight.  Or simply if you are in search of Vegan Cake or Cookie Decoration, then you have landed into the right recipe here.

    This simple recipe uses just three ingredients and works wonderfully for cakes, cookies, and decorative piping. Bonus? No more raw egg worries! This is the best Vegan Icing in my terms.

Confectioners' Sugar or Normal Sugar?

    While both normal powdered sugar and confectioners' sugar work well for this recipe, I have used Icing Sugar here for a smoother texture. But if you don’t have it on hand, you can powder and sieve regular white sugar—it works just fine!

One other ingredient I’ve added to the icing is Lemon Juice, which helps avoid crystallisation of sugar and also helps to harden the icing once set.

    The trickiest part is getting the royal icing to land on the cakes in the perfect consistency. Sometimes, we might need more water; sometimes, it needs less. But the wonderful thing is that you can manipulate the icing to get the proper consistency by adding more water or more Sugar.  Just keep in mind to add water in drops, though! It’s awesome! So, you see—no strict rules, yet it is a foolproof recipe. I know why I love this royal icing recipe.

Ingredients for Vegan Royal Icing

• 2 cups (250g) Icing Sugar (sifted)
• 3–5 tablespoons (45–75ml) Cold Water (adjust for consistency)
• 1/2 teaspoon (2.5ml) Glycerine (optional – keeps icing soft, skip for a firmer set)
• 1 teaspoon (5ml) Lemon Juice or Aquafaba (optional – helps with structure and setting)

Note: Start with 3 tablespoons and add the remaining water drop-by-drop until it reaches a thick, ribbon-like consistency that coats the back of a spoon.

Method: Step-by-Step Guide to Making Simple Vegan Royal Icing

    Achieving the perfect egg-free royal icing is all about the right consistency. Follow these steps to make a silky, smooth, and glossy icing that’s ideal for decorating cakes, cookies, or festive bakes!

Step 1: Sift the Icing Sugar

• Begin by sifting the icing sugar into a clean, dry mixing bowl. This helps remove any lumps and ensures a super smooth texture in the final icing.
  

   

  Pro Tip: If your icing sugar is particularly clumpy, sift it twice for an extra-fine finish!

Step 2: Add Liquid Ingredients

• Start by adding 4 tablespoons of water and your choice of lemon juice or aquafaba (if using).

  Pro Tip: Do not over-whisk. We want to incorporate the liquids gently to avoid air bubbles. If you see a bubble, prick it with a toothpick immediately.

• Stir well using a spoon or spatula until the mixture becomes smooth and lump-free.

  Pro Tip: Lemon juice helps balance the sweetness and adds a subtle tang, while aquafaba enhances the icing’s structure—making it a great choice for intricate decorations.

Step 3: Add Glycerine (Optional)

• If you want a soft-set icing (perfect for cookies), mix in a few drops of glycerine.
• If you prefer a hard-setting icing (ideal for intricate decorations that need to hold their shape), skip the glycerine.

   

  Pro Tip: A hard-set icing is best for decorating Christmas cakes or wedding cakes, while a softer one works well for cookies that need a bit of chew.

Step 4: Adjust the Consistency

This is where you fine-tune your icing depending on its purpose:

• For thicker icing (best for piping & details): Add more sifted icing sugar, a tablespoon at a time, until you reach a stiff but spreadable texture.

• For runnier icing (ideal for glazing cakes/cookies): Add a few drops of water at a time and stir well until you achieve a smooth, flowing consistency.

   

  Pro Tip: If you’re decorating cookies, use a thicker icing for outlining and a runnier version for flooding the inside—it creates a flawless professional finish!

Step 5: Beat Until Glossy

• Once you’ve reached the desired consistency, use a whisk or electric mixer to beat the icing for about 1 minute until it becomes smooth, glossy, and easy to spread.

   

  Pro Tip: Overmixing can introduce too many air bubbles, so mix just until the icing looks silky and shiny. If bubbles form, gently tap the bowl on the counter to release them.

Step 6: Store or Use Immediately

• If using right away, spread or pipe the icing onto your cake or cookies.
• If storing, cover the bowl with cling film (touching the surface) to prevent a dry crust from forming.

   

  Pro Tip: Royal icing dries quickly! Always keep it covered while working, and if it starts to thicken, add a few drops of water and stir to bring it back to the right consistency.

Now you’re all set to decorate like a pro! Enjoy your vegan, egg-free, dairy-free royal icing on cakes, cookies, or festive treats! 

How Long Does it Take for Royal Icing to Dry?

• The icing forms a skin within 1 hour and hardens completely in 4–6 hours.
• This firm yet melt-in-the-mouth texture is reminiscent of bakery-style cakes from Kerala and Coimbatore.
• Classic royal icings are made with meringue powder, but this version is slightly harder, just like the ones found in our local bakeries in Coimbatore & Kerala.

Pro Tips & Notes for Perfect Vegan Royal Icing

• Want a firmer set? Skip glycerine and use lemon juice instead of water.
• Need a glossy finish? Add a tiny drop of corn syrup.
• Too runny? Add a spoonful of icing sugar at a time to thicken. 
• Coloured Icing? Use gel food colouring to avoid altering consistency.

FAQs

• Aquafaba is the liquid from canned chickpeas, often used as an egg white substitute in vegan baking. While I haven’t personally used it in this recipe, some people find it helps with structure and stability.
