To make a gingerbread house that actually stands up, you need two things a batch of soft Christmas biscuits won’t give you: a stiff, low-spread dough rolled to an even 5 mm, and a thick royal icing that sets like mortar. Get those right and the rest is patience. This guide to how to make a gingerbread house gives you a from-scratch gingerbread house recipe engineered for structure, a measured template, step-by-step assembly, and an honest look at whether a supermarket gingerbread house kit is the better call for your December.
Key takeaways
- Build with construction dough, not cookie dough. Less butter, more flour, rolled to an even 5 mm so the walls are rigid and the pieces stay square in the oven.
- Royal icing is the glue. Beat it to stiff peaks: stand a knife in it and the trail should hold, not slump. Runny icing is the single most common reason walls slide.
- Let the walls set before the roof. Give the four walls at least 1–2 hours to firm up; a wet base under a heavy roof is how houses collapse.
- A good supermarket kit costs around £5 and takes 20 to 40 minutes; from scratch costs a little less in ingredients but a full afternoon. Which is “better” depends on what you actually want from the day.
- From-scratch yield: one standard house (six pieces) from 350 g flour, plus enough trimmings for a tray of biscuits.
A gingerbread house is really a small engineering project dressed up as baking, and that is the whole charm of it. The dough is the timber, the royal icing is the cement, and gravity is the examiner. This guide gives you the full from-scratch route — dough, icing, template and assembly — and then, because it is honest to do so, weighs it against buying a kit. There is no wrong answer; there is only the one that suits your house, your children and the hour you have.
Make or buy
Scratch vs kit: the honest call
If you want the short version: buy a kit for a quick, low-stakes afternoon with young children; bake from scratch when the house itself is the point. Kits are quicker, more forgiving and genuinely cheap. From-scratch tastes better, looks more impressive and lets you build any shape you like — but it asks for a free afternoon and a steady hand with the icing.
The consumer group Which? has tested supermarket kits and found the quality varies a great deal between retailers, which is the most useful thing to know before you buy: a kit is only as good as the brand behind it, and the cheapest is sometimes the best. Treat the table below as a guide to the trade-off rather than a league table of prices, which shift every season.
| From scratch | Supermarket kit | |
|---|---|---|
| Hands-on time | About 5 hours across a day (most of it hands-off setting time) | 20–40 minutes |
| Rough cost | Storecupboard ingredients, typically under the price of a mid-range kit, and you get biscuits from the offcuts | Around £5 for a standard supermarket kit, more for a large or branded one |
| Result | Sturdier, better-tasting, any shape you design | Reliable and uniform; some kits are thin and snap easily |
| Best for | Older children and adults; when you want a centrepiece | Little ones, a school night, or a first attempt |
| The catch | Walls can spread or bow if the dough is too soft or the icing too loose | The supplied icing sachet is often weak — many builders mix their own royal icing instead |
Doing it cheaply and well
A from-scratch house is mostly flour, sugar and syrup — storecupboard staples — so it rarely costs more than a kit and often less. Roll and cut the offcuts into stars and gingerbread people; baked alongside the house, they become a second batch of biscuits at no extra cost and no waste. If you would rather buy, the budget supermarkets often hold up well in independent tests, so the cheapest kit on the shelf is not automatically the weakest. You do not need the branded one to get a good house.
The recipe
The gingerbread house recipe (dough that builds)
The trick to a house that stands is a drier, denser dough than you would use for eating biscuits. Less butter means less spread in the oven, so the pieces keep the straight edges your walls depend on. Chill the dough, roll it to an even 5 mm, and re-trim the edges against your template the moment the pieces come out of the oven, while they are still soft.
Construction gingerbread
Makes one standard house (six pieces) plus offcut biscuits · Prep 45 min · Bake 12–15 min · 180°C / 160°C fan / gas 4
Ingredients
- 350 g plain flour, plus extra for rolling
- 1 tsp bicarbonate of soda
- 2 tsp ground ginger
- 1 tsp ground cinnamon
- ½ tsp ground mixed spice (or ground cloves)
- Pinch of salt
- 125 g unsalted butter, cubed
- 175 g dark brown soft sugar
- 4 tbsp (about 85 g) golden syrup
- 1 medium egg, beaten
Method
- Sift the flour, bicarbonate of soda, ginger, cinnamon, mixed spice and salt into a large bowl.
- Melt the butter, sugar and golden syrup together in a pan over a low heat, stirring until smooth. Let it cool for a couple of minutes so it will not cook the egg.
- Pour the melted mixture and the beaten egg into the dry ingredients and bring together to a firm dough. It should be stiff, not sticky; work in a little more flour if it clings.
- Wrap and chill for 30 minutes. Cold dough holds its edges.
- Roll out on a lightly floured surface to an even 5 mm — two wooden spoon handles either side of the dough make a quick depth guide. Cut your pieces (see the template below) and lift them onto lined baking trays.
- Bake at 180°C / 160°C fan / gas 4 for 12–15 minutes, until evenly darkened and firm. Larger pieces sit at the upper end of the time.
- Straight from the oven, lay the template back over each warm piece and trim any spread with a sharp knife. Leave to cool flat and harden completely before building.
Why this works
Three things give you rigid walls. The butter ratio: at 125 g to 350 g flour the dough spreads little, so edges stay true. The 5 mm thickness: thinner pieces bake brittle and crack under the roof; much thicker and they stay soft in the middle. The warm re-trim: even a careful dough creeps a millimetre or two, so cutting back to the template while soft keeps your joints flush. Bake the gable ends and roof panels last if your oven runs hot at the back — the larger pieces are the ones you cannot afford to scorch.
The glue
Royal icing: the recipe that holds it together
Royal icing is the mortar, and it has to be stiff. Beaten properly it pipes in firm ridges, grips the joints and sets hard within an hour or two. The test is simple: stand a knife upright in the bowl and the icing should hold the trail without slumping back. If it sags, beat in more icing sugar.
Stiff royal icing (the mortar)
Enough to build and ice one house · 5 minutes · no cooking
Ingredients
- 2 medium egg whites (or 15 g dried egg-white or meringue powder mixed with 75 ml water)
- 400–450 g icing sugar, sifted
- ½ tsp lemon juice (optional, helps it set)
Method
- Whisk the egg whites (or made-up egg-white powder) until just frothy.
- Beat in the sifted icing sugar a third at a time until the icing is smooth, glossy and very stiff.
- Add the lemon juice if using and beat again. You are aiming for a paste that holds a stiff peak.
- Keep the bowl covered with a damp cloth while you work — royal icing crusts over fast.
- For gluing walls, use it thick. For piping snow and detail later, loosen a small portion with a few drops of water.
If you are building with very young children or anyone avoiding raw egg, the dried egg-white or meringue-powder version sets just as hard and sidesteps the food-safety question entirely. A piping bag with a small plain nozzle gives you far more control than a knife for the joints; a freezer bag with one corner snipped off does the same job.
The plan
Template and measurements
One standard house needs six pieces: two walls, two roof panels and two gable ends — cut two of each shape from the dough. Draw the shapes on card or baking paper to the measurements below, cut them out, and use them as stencils on the rolled dough. Keeping every piece to the same 5 mm depth is what makes the joints meet cleanly.
The gable ends are the house-shaped pentagons: 130 mm wide, rising to 90 mm at the eaves and 150 mm at the apex of the roof. The roof panels (150 mm by 110 mm) are deliberately a little wider than the walls so they overhang at the eaves — that overhang is what gives the finished house its tidy roofline. If you would like a chimney, cut four small rectangles for it and bake them with the offcuts; a chimney is decorative, so size it by eye.
For a smaller house
Scale every measurement down by the same proportion — reduce each dimension to about three-quarters and the pieces still fit together. Keep the 5 mm thickness whatever the size; that is the one number you do not change, because it governs strength rather than scale.
The build
Step-by-step assembly
Build on the board you intend to serve it on — a cake board or a flat tray — because a finished house does not move. Work in two stages: walls first, left to set, then the roof. The timeline below shows where the patience goes.
- Glue the first corner. Pipe a thick line of royal icing down the side edge of one gable end and press a wall to it at a right angle. Hold for a minute until it grips.
- Add the second wall and gable the same way, so you have four walls forming a box. Pipe icing along every inside joint to reinforce it. Tins of beans or upturned mugs propped against the walls hold everything square while it sets.
- Let the walls set — this is the step people skip. Leave the box for at least 1–2 hours (longer is better) until the joints are rock-hard. A roof on soft walls is how a house bows outward and slides.
- Fix the roof. Pipe icing along the top edges of all four walls, lay on the first roof panel and hold it, then the second so they meet at the ridge. Pipe a generous line of icing along the ridge to seal and hide the seam.
- Set again before decorating. Give the roof 30 minutes to firm up before you add weight to it.
A roof on soft walls is how a house collapses. The hour you spend waiting is the hour that saves the build.
The fun part
Decorating ideas
This is where the children earn their keep, and where a plain box becomes a house. Pipe stiff white royal icing along the ridge and eaves for snow and icicles, then work downward. A few ideas that look the part with British sweets you already have in the cupboard:
- Roof tiles: overlapping rows of chocolate buttons, mini shredded wheat, or flaked almonds laid like slates.
- A snowy path: a trail of white chocolate buttons or sifted icing sugar across the board.
- Sweets that read as Christmas: Smarties and M&Ms for baubles, candy canes either side of the door, a dusting of icing sugar over the whole thing just before it goes on the table.
- Stained-glass windows: cut window holes before baking, drop in a crushed boiled sweet (a clear fruit one), and it melts to a pane of coloured “glass” as the gingerbread bakes. Let it cool fully before you move the piece.
A no-spend decorating box
You do not need a special kit of decorations. Leftover sweets from selection boxes, a bag of cheap chocolate buttons, and the icing sugar already in the cupboard will dress a house beautifully. Sifted icing sugar over the finished roof is the cheapest and most convincing snow there is.
Get ahead
Make-ahead and timeline
A gingerbread house is an ideal get-ahead bake, because baked gingerbread keeps for a week or more in an airtight tin. You can spread the work over two or three evenings rather than one long afternoon, which is the saner option in a busy December.
- Up to a week ahead: make and bake all six pieces, then store them flat in an airtight tin. They harden as they sit, which is exactly what you want for building.
- The day of building: make the royal icing fresh (it is a five-minute job) and assemble. Build the walls in the morning, leave them to set over lunch, and roof and decorate in the afternoon.
- Once finished: a decorated house keeps for a couple of weeks as a centrepiece. It is edible throughout, though by then it is firmly in the “more decoration than pudding” category.
For the wider Christmas-week plan, the December Christmas to-do list sets out when to tackle the make-ahead jobs around the cooking. A gingerbread house slots neatly into the quiet weekend before the main event.
When it goes wrong
Troubleshooting
The walls are bowing or sliding outward
Two usual causes: the icing was too loose, or the walls did not set before the roof went on. Stiffen the icing with more sifted icing sugar so it holds a knife-trail, prop the walls with tins while they set, and give the box a proper 1–2 hour rest before roofing. If a wall is already leaning, pipe a thick fillet of icing along the inside joint and prop it upright until it hardens.
The gingerbread came out soft and bendy
It was either underbaked or has drawn in moisture. Bake the pieces until evenly firm and a shade darker, not pale; a few extra minutes does no harm to structural gingerbread. Once baked, store the pieces in an airtight tin — left out in a steamy kitchen, gingerbread softens within hours, and humidity is the quiet enemy of a finished house.
The dough spread and lost its straight edges
The dough was too warm or too soft. Chill it well before rolling, keep your butter ratio as the recipe gives it, and re-trim each piece against the template the moment it leaves the oven while it is still soft. That warm re-trim rescues almost any spread.
The icing will not hold the pieces together
It is too thin. Royal icing for gluing should be genuinely stiff — beat in more icing sugar until a knife stands up in it. Hold each joint in place for a full minute, and resist adding the next piece until the last one has gripped.
My supermarket kit collapsed
The icing sachet supplied with many kits is on the weak side. If a kit gives you trouble, mix a batch of the stiff royal icing above and use that instead — it is the same fix experienced builders reach for, and it costs pennies.
Buying well
How to choose a gingerbread house kit, if you would rather buy
If a kit is the right call for your December, choose on three things: the thickness of the gingerbread, the strength of the icing, and how much assembly is left to you. Independent testing has found the quality differs sharply between supermarkets, with some budget kits scoring well and some big names disappointing, so price is a poor guide to result.
- Thicker gingerbread is sturdier. Thin, snap-prone pieces are the commonest complaint; if you can see through the box, weigh it in your hand.
- Plan to upgrade the icing. The supplied sachet is often the weak link. A homemade batch of stiff royal icing turns a wobbly kit into a solid one.
- Pre-assembled vs flat-pack. Some kits arrive as a built shell you only decorate — far easier with small children; others are flat pieces you glue yourself, which is more satisfying but more work.
- Check the build-by date. Kits bought early in the season and left in a warm cupboard can soften; build within the use-by window.
We name no single “best buy” here because kits change every season and the honest finding is that there is no permanent winner — the sensible move is to check a current independent taste-test the year you buy. Either way, the homemade-icing tip above is the one upgrade that improves almost any kit.
Questions
Gingerbread house FAQ
Can I make a gingerbread house ahead of time?
Yes. Bake the pieces up to a week ahead and store them flat in an airtight tin — they harden as they sit, which makes building easier. Make the royal icing fresh on the day you assemble, as it is only a five-minute job.
How far in advance can I build the whole house?
A finished, decorated house keeps as a centrepiece for a couple of weeks if it stays dry and cool. It is edible throughout, though by the second week it is firmer than fresh gingerbread.
Why did my gingerbread house collapse?
Almost always one of two reasons: the royal icing was too thin to hold, or the walls were not given time to set before the roof went on. Use stiff icing that holds a knife-trail, and let the four walls firm up for 1–2 hours before roofing.
What is the best icing to glue a gingerbread house?
Stiff royal icing made from egg white (or dried egg-white powder) and icing sugar, beaten until a knife stands up in it. It sets hard like mortar. The thin icing supplied with shop kits is the usual weak point.
Can I use egg-free icing for a gingerbread house?
Yes. Dried egg-white powder or meringue powder mixed with water makes royal icing that sets just as firm and avoids raw egg, which is the safer choice when young children are helping or eating.
How thick should I roll gingerbread for a house?
An even 5 mm. Thinner pieces bake brittle and crack under the weight of the roof; much thicker and they stay soft in the middle. A wooden spoon handle on each side of the dough makes a quick depth guide.
Is it cheaper to make or buy a gingerbread house?
Making from scratch is usually a little cheaper, as it uses storecupboard ingredients and the offcuts become biscuits. A standard supermarket kit costs around £5 and saves you the afternoon. Cost is close; the real difference is time and result.
What can I use instead of a template?
Any straight-edged guide will do — draw the shapes on card to the measurements above, or use a clean cereal box. The key is cutting two of each piece to the same size so the walls meet squarely.
How do I make stained-glass windows?
Cut window holes in the dough before baking, drop a crushed clear boiled sweet into each, and the sweet melts to a pane of coloured “glass” as the piece bakes. Let it cool completely before moving the piece.
Can young children make a gingerbread house?
Yes, with the build split sensibly: an adult bakes and glues the structure, the children decorate once the walls and roof have set. A pre-assembled kit, or your own pre-built shell, makes it a relaxed job rather than a fraught one.
Once the house is built, the rest of the festive table tends to follow. If you are cooking the lot, our guides to bread sauce, turkey crown and pigs in blankets cover the savoury end, and you will find the full set in our Christmas recipes collection.
