Why Royal Icing Makes Cookies Shine
Royal icing is a versatile icing that dries hard, making it perfect for detailed designs and stacking cookies. It’s safe, elegant, and customizable, allowing bakers to create everything from simple dots and lines to intricate snowflakes and festive scenes.
The key is choosing the right consistency for the style of decorating you want:
Stiff or piping consistency: For fine lines, details, and accents.
Medium consistency: For borders or slightly filled shapes.
Flood/runny consistency: For filling in larger areas smoothly.
How to Make Royal Icing for Decorating Cookies
Royal icing is a smooth, glossy icing that dries hard, making it perfect for piping outlines, flooding cookies, and creating intricate designs. Follow these steps to get professional-looking results every time.
Step-by-Step Method
1. Prepare Your Workspace
Make sure all bowls, mixers, and utensils are clean and dry. Even a small amount of grease or moisture can prevent the icing from setting correctly.
Sift your icing sugar to avoid lumps.
2. Whisk the Egg White
Place the pasteurised egg white in a clean bowl.
Using a hand whisk or electric mixer, whisk lightly until frothy. This step helps incorporate air and gives the icing a smoother texture.
3. Add the Icing Sugar Gradually
Slowly add the sifted icing sugar to the egg white while mixing on low speed.
Mix until the sugar is fully incorporated. The mixture should start looking glossy and thick.
4. Add Flavouring
Add ½ tsp of vanilla extract or lemon juice for a subtle flavour.
Mix until fully combined.
5. Beat to Glossy Perfection
Increase the mixer speed to medium-high and beat for 5–6 minutes.
The icing should be thick, smooth, and glossy, forming soft peaks that hold their shape for piping.
Adjust the Consistency
Royal icing consistency is key depending on the decorating technique:
Stiff/Piping Consistency (for outlines and details):
Should hold its shape on a spoon or piped line.
If too soft, add a little more sifted icing sugar.
Flood/Runny Consistency (for filling areas):
Should flow slowly and settle flat within 10–15 seconds when you drag a knife through it.
Thin with tiny drops of water until it reaches the correct flow.
Royal Icing Decorating Techniques
1. Piping Outlines and Details
Consistency: Stiff-peak icing that holds its shape.
Tools: Small round piping tip (Wilton 1–3) in a piping bag or parchment cone.
Technique: Hold the bag nearly upright, apply steady pressure, guide the icing without dragging the tip. Stop pressure and lift to end the line cleanly.
2. Piping Dots (Accents)
Consistency: Same stiff icing as outlines.
Technique: Hold tip close to cookie, squeeze gently, lift straight up. Perfect for snowflake accents or small decorative dots.
3. Flooding / Filling
Consistency: Runny icing (thin with water so it settles flat in 10–15 seconds).
Technique: Pipe a border first using stiff icing as a dam. Fill the interior with flood icing, guide to edges with a toothpick. Let dry for 6–8 hours or overnight.

Tips for Perfect Royal Icing
Always sift your icing sugar to avoid gritty icing.
Work in small batches if you want multiple colours or consistencies.
Practice piping on parchment paper if you are new to cookie decorating.
Avoid adding too much water at once; thin slowly to control consistency.
Optional: Colouring the Icing
Use gel food colouring to tint your icing without affecting the consistency.
Mix small amounts at a time until you reach the desired shade.
Store and Use
Keep unused icing covered with cling film touching the surface to prevent drying.
Royal icing sets at room temperature in 6–8 hours or overnight, depending on humidity.
⚠️ Important Food Safety Note
For safest results, make royal icing with meringue powder or pasteurised egg whites (sold in cartons). Both are heat-treated to remove the risk of Salmonella.
If using raw, unpasteurised egg whites, be aware of a small foodborne illness risk. Avoid serving to young children, pregnant women, the elderly, or anyone with a weakened immune system.
