How to Make Shortbread Cookies with Royal Icing (Canadian Bakery Recipe)

There's something deeply satisfying about a perfect shortbread cookie - buttery, melt-in-your-mouth, with a smooth royal icing decoration that looks almost too good to eat. The good news? The recipe is genuinely simple. Five ingredients for the cookie, five for the icing. What takes practice is the decorating - and that's where this guide goes deep.
Whether you want to try baking these at home, or you're just curious what goes into the cookies you've been ordering, here's exactly how Canadian handmade shortbread cookies are made.

The Recipe

Shortbread Cookies (makes 24)

Prep time: 15 minutes | Chill time: 30 minutes | Bake time: 12–14 minutes

Ingredients:

• 225g unsalted butter, softened (this is the whole flavour — use real butter, not margarine)
• 300g wheat flour
• 100g sugar
• 1 tsp vanilla extract
• ¼ tsp salt

Instructions:

1. Beat butter and sugar together until pale and fluffy, about 3–4 minutes. Don't rush this step - proper creaming gives you that melt-in-your-mouth texture.
2. Mix in vanilla extract and salt. Scrape down the sides of the bowl.
3. Add flour gradually on low speed, mixing until the dough just comes together. Stop the moment it forms - overworking makes cookies tough. The dough should be soft but not sticky.
4. Flatten into a disc, wrap in plastic wrap, and refrigerate for at least 30 minutes. Cold dough holds its shape when cut and baked.
5. Preheat oven to 325°F (165°C). Roll chilled dough on a lightly floured surface to about 6mm (¼ inch) thick. Cut into shapes with cookie cutters.
6. Bake for 12–14 minutes until edges are just barely golden. Shortbread should stay pale - too much colour means it's overbaked.
7. Cool on the pan for 5 minutes, then transfer to a wire rack. Cookies must be completely cool before decorating - any warmth will melt your icing.

Royal Icing

Ingredients:

• 400g powdered sugar (icing sugar), sifted
• 2 egg whites (or 3 tsp meringue powder + 6 tbsp water)
• 2 tbsp water, added gradually
• ½ tsp vanilla extract
• Gel food colouring — one colour per bowl

Instructions:

1. Beat egg whites until foamy.
2. Add sifted powdered sugar gradually, then vanilla extract.
3. Add water a little at a time until you reach your desired consistency.
4. Beat on medium-high for 3–4 minutes until thick, glossy, and white.
5. Divide into small bowls — one per colour. Add gel food colouring and stir well.
6. Keep bowls covered with a damp cloth when not in use or the icing will crust over.

The 5-Ingredient Shortbread Base

Classic shortbread has no eggs, no leavening, no fuss. Just butter, flour, sugar, vanilla, and a pinch of salt. That simplicity is exactly why the quality of each ingredient matters so much - real butter is non-negotiable. Margarine won't give you the same flavour or texture.
The full recipe with exact amounts and timers is above - you can even scale it up or down using the serving adjuster.
The one thing most people get wrong: overworking the dough. Once the flour is added, mix only until the dough just comes together. Overworking develops the gluten and makes your cookies tough instead of crumbly and tender.

Royal Icing: The Decorator's Secret Weapon

Royal icing is what separates a basic cookie from a bakery-quality decorated one. It dries completely hard, holds colour beautifully, and lets you create clean, detailed designs - from simple flooded bases to intricate emoji faces and hand-piped flower petals.

The Two Consistencies You Need to Know

This is the most important thing about royal icing that nobody tells beginners:
You need two different consistencies from the same batch, and you use them for different purposes.
Outline / piping consistency - thick, like peanut butter. Holds its shape when piped. Use this for outlines, details, fine lines, and any decorating that needs structure (like the emoji expressions, flower petal lines, or writing text).
Flood consistency - thinner, like slowly dripping honey. Spreads and self-levels to fill in a shape completely. Use this for base colour coverage before adding details on top.
To go from piping to flood: add water one drop at a time, stirring after each drop. You're looking for icing that drips off your spoon in a slow, smooth ribbon and settles flat within about 10 seconds.

Always Use Gel Food Colouring

Liquid food colouring from the grocery store adds too much water and throws off the icing consistency. Gel colouring (available at Bulk Barn or any baking supply store) gives you vivid, saturated colour without changing the texture at all. A tiny amount goes a long way.

How to Decorate Like a Pro: Flooding Technique

The flooded cookie look - smooth, perfectly even colour with clean edges - is the foundation of almost all decorated shortbread. Here's the step-by-step:

1. Outline first. Using a piping bag with a small round tip (or a squeeze bottle), pipe a border around the edge of the cookie with your thicker icing. This acts as a dam to keep the flood icing inside.
2. Let the outline set. Wait 5–10 minutes so it firms up slightly.
3. Flood the centre. Drop flood-consistency icing inside the outline, then use a toothpick or small offset spatula to spread it to the edges. It will self-level and smooth out.
4. Pop any air bubbles immediately with a toothpick.
5. Let it dry at least 20–30 minutes before adding any detail work on top.

Decoration Ideas: What You Can Make

Once you've got the flooding technique down, the creative possibilities are endless. Here are some of the designs that work beautifully on shortbread:

Emoji Cookies

Start with a flooded yellow base. Once dry, use a thin piping tip or a toothpick with brown icing to draw the facial expressions. For the heart-eyes emoji, pipe small red heart shapes while the base is still slightly tacky so they adhere cleanly. For the winking face, simple curved lines are all you need — the geometry of the emoji does the work.

Flower Cookies

Cut your dough into flower shapes, flood each petal in a different pastel colour, and add a small white dot in the centre. The trick is getting clean colour separation between petals — pipe a clean outline around each petal and let it set before flooding the adjacent one. This stops colours from bleeding into each other.

Writing and Text

Writing on cookies requires piping-consistency icing and a very small round tip (size 1 or 2). Practice letters on parchment paper first. Short words work best — names, "Happy Birthday", "Thank You". The shorter the word, the cleaner the result.

Butterflies and Custom Shapes

More complex shapes like butterflies work best with a combination: flood the base colour, let it dry fully overnight, then add detail lines and accents on top. Layering is the key — never rush to the next step.

Pro Tips from the Bakery

A few things that make the biggest difference:

• Chill the cut cookies for 10 minutes before baking: this helps them hold their shape perfectly in the oven
• Every oven is different: check at the 11-minute mark the first time you make these. You want pale golden edges, not brown
• Icing dries from the outside in: even if the surface looks dry, the inside may still be soft. Always wait the full 6–8 hours before stacking or packaging
• Humidity is the enemy of royal icing: on humid days, icing takes longer to dry and can stay tacky. A dehumidifier or fan helps
• Piping bags vs squeeze bottles: squeeze bottles give you more control for flooding, piping bags are better for detail work. Most serious decorators use both

Frequently Asked Questions

Can I make the dough ahead of time?

Absolutely. The dough keeps in the fridge for up to 3 days, or in the freezer for up to a month. Thaw overnight in the fridge before rolling.

How long does royal icing last?

Freshly made royal icing keeps for up to a week in an airtight container at room temperature. Press plastic wrap directly onto the surface to prevent crusting. Re-whip briefly before using.

Can I use store-bought icing instead of royal icing?

You can, but it won't dry hard. Buttercream and store-bought frosting stay soft, which means the cookies can't be stacked and the designs won't hold their crisp edges. Royal icing is worth making from scratch for decorated cookies.

Why did my icing bleed or spread?

Either the flood icing was too thin, you didn't wait long enough for the outline to set, or two colours were placed too close together while still wet. Slow down between steps — this is almost always a patience issue.

Do I need special equipment?

Not to start. You can use a zip-lock bag with a tiny corner snipped off instead of a piping bag. A toothpick covers most spreading and detail work. Cookie cutters are helpful but a sharp knife works too. As you get more into decorating, a set of piping tips is worth the $10–15 investment.

Ready to Bake?

The recipe is above — scaled for 24 cookies, but you can adjust it up or down with the serving tool. Start with simple shapes and one colour before jumping to multi-colour designs. And if your first batch doesn't look perfect, eat them anyway — they'll still taste incredible.
