Crisp Buttery Christmas Biscuits with Easy Royal Icing
These decorated Christmas biscuits are the ones I reach for every year. The dough rolls out without a fight, holds its shape in the oven, and bakes into crisp, buttery rounds that stand up to a heavy coat of icing.
The royal icing is a 3-ingredient mix that hardens to a glossy shell. No raw eggs, no fuss, just clean white icing you can tint any colour and pipe as neatly or as playfully as you like.
Why These Christmas Biscuits Work
The dough is forgiving. A little extra flour won’t ruin it, and a short chill makes it a breeze to roll. The biscuits bake with clean edges and a sandy, shortbread-like crumb that stays sturdy even under a thick layer of icing.
The icing sets firm and shiny. Meringue powder gives it structure so you can stack the biscuits in tins without smudging. It’s the kind of weekend project that feels festive without being fussy.
Ingredients
- 2 1/4 cups (280 g) all-purpose flour, spooned and levelled: gives the biscuits their sturdy frame
- 1 cup (2 sticks, 226 g) unsalted butter, softened: take it out of the fridge an hour before you start
- 3/4 cup (150 g) granulated sugar: fine caster sugar works nicely too
- 1 large egg, at room temperature: helps bind without overworking the gluten
- 1 teaspoon vanilla extract: use a good-quality one, the flavour really comes through
- 1/2 teaspoon baking powder: just enough lift to keep them crisp, not puffy
- 1/4 teaspoon fine sea salt: cuts the sweetness
- 2 cups (250 g) icing sugar, sifted: the base for the royal icing
- 2 tablespoons meringue powder: find it in the baking aisle or order it online, it sets the icing without raw whites
- 3 to 4 tablespoons water, plus more as needed: you’ll adjust it to get the right piping consistency
- Gel food colouring, sprinkles, or sanding sugar: for decorating (optional)
Flavor Twists and Swaps
- Citrus swap: replace the vanilla with 1 teaspoon of finely grated lemon or orange zest. The bright note cuts through the buttery dough.
- Almond touch: use 1/2 teaspoon almond extract instead of vanilla. A little goes a long way, so don’t overdo it.
- Spiced dough: add 1 teaspoon cinnamon and a pinch of nutmeg to the flour for a warmer holiday vibe.
- Dairy-free: use a vegan butter stick that holds its shape and skip the egg. Replace the egg with 2 tablespoons of cold water mixed into the creamed butter and sugar.
- Icing without meringue powder: you can use 2 tablespoons of pasteurized liquid egg whites in place of the powder and water, but the icing may take a bit longer to set fully.
For something softer and fluffier, try my Soft Lemon Shortbread Cookies with a glaze instead of royal icing.
How to Make Decorated Christmas Biscuits
Step 1: Cream the Butter and Sugar
Preheat the oven to 350°F (180°C) and line two baking sheets with parchment. In a large bowl, beat the 1 cup softened butter and 3/4 cup sugar together with an electric mixer on medium speed until pale and fluffy, about 2 to 3 minutes.
The mixture will lighten in colour and feel like damp sand when you pinch it. Don’t rush this step; well-creamed butter is what gives the biscuits their crisp, tender crumb.
Step 2: Make the Dough
Beat in the 1 large egg and 1 teaspoon vanilla until just blended. In a separate bowl, whisk the 2 1/4 cups flour, 1/2 teaspoon baking powder, and 1/4 teaspoon salt. Add the dry ingredients to the butter mixture in two additions, mixing on low until a soft, cohesive dough comes together.
The dough will look a bit shaggy at first but should pull together cleanly. Shape it into a flat disc, wrap tightly in cling film, and chill for at least 30 minutes. Chilled dough is much easier to roll without adding extra flour.
Step 3: Roll and Cut the Biscuits
Lightly flour your work surface and rolling pin. Roll the chilled dough to 1/4 inch thickness. If the dough cracks at the edges, let it sit for 5 minutes to soften slightly, then try again.
Press your cutters straight down without twisting; a clean cut helps the biscuits keep their shape in the oven. Gather and reroll the scraps only once, then cut more shapes until all the dough is used.
Step 4: Bake the Biscuits
Arrange the cutouts on the prepared baking sheets, leaving about 1 inch between them. Bake one sheet at a time for 10 to 12 minutes, until the edges turn just barely golden.
The biscuits will feel soft when hot but firm up as they cool. Let them rest on the sheet for 5 minutes, then transfer to a wire rack to cool completely before icing.
Step 5: Mix the Royal Icing
In a clean, grease-free bowl, whisk together 2 cups icing sugar and 2 tablespoons meringue powder. Add 3 tablespoons water and beat with a hand mixer on low until smooth and thick, about 3 minutes.
The icing should hold a peak when you lift the whisk, then slowly melt back into the bowl. If it’s too stiff, add water a few drops at a time; if too runny, beat in a little more icing sugar. Divide into smaller bowls and tint with gel food colouring if you like.
Step 6: Decorate and Let Set
Pipe outlines with a #2 round tip, or use a piping bag with the corner snipped off for simple squiggles. Flood the centres with slightly thinner icing (add a few drops of water to a portion), using a spoon or a small squeeze bottle, and use a toothpick to pop any air bubbles.
Add sprinkles, sanding sugar, or tiny candies while the icing is still wet. Let the biscuits sit uncovered at room temperature for 2 to 3 hours until the icing is fully set and hard. Then they’re ready to stack, box up, or hang on the tree.
Tips for Neatly Decorated Biscuits
- Use a little powdered sugar rather than flour for dusting your rolling surface. Flour can leave white patches on the baked biscuits, while powdered sugar dissolves away.
- If the dough softens as you work, slide the cut shapes onto a baking sheet and chill them for 10 minutes before baking. Cold dough spreads less in the oven.
- Chill your scraps before rerolling them. A quick 10-minute rest stops the dough from getting tough and makes it easier to handle.
- Gel food colouring gives you vibrant colours without thinning the icing. Liquid drops can water it down and make it harder to pipe.
- Let the icing dry completely before stacking. Even a little dampness leads to smudged designs and stuck-together biscuits.
Storing Decorated Biscuits
- Room temperature: store the fully dried biscuits in an airtight container, layered between sheets of parchment. They stay crisp for up to a week.
- Refrigerate: avoid the fridge. The moisture softens both the biscuit and the icing, leaving them sticky.
- Freeze: freeze undecorated baked biscuits in a tightly sealed container for up to a month. Thaw on the counter, then decorate fresh. Iced biscuits don’t freeze well because the icing can crack and weep when it thaws.
Frequently Asked Questions
Can I make the dough the night before?
Yes. Wrap it well and refrigerate for up to 2 days. Let it sit at room temperature for 10 to 15 minutes before rolling so it’s pliable.
My biscuits spread and lost their shape. What went wrong?
The butter likely got too warm during rolling or the dough wasn’t chilled enough. Chilling the cut shapes on the sheet for 10 minutes before baking fixes that next time.
Can I skip the meringue powder?
You can, but the icing won’t set as firm or glossy. Replace the powder and water with 2 tablespoons of pasteurized liquid egg whites, then add icing sugar until the consistency is thick enough to pipe.
How do I get the icing bright white?
Use 1/4 teaspoon of clear vanilla extract or skip the vanilla altogether. A tiny drop of violet gel colouring cancels out any yellow tint, leaving a bright white finish.
Can I freeze the baked biscuits before decorating?
Absolutely. Store them unfrosted in a freezer bag for up to a month. Thaw them uncovered on a wire rack so they don’t steam, then ice as usual.
