Drømmekage — Danish dream cake with a caramelised coconut top

i. Origin & history

Drømmekage is so closely associated with one small town in northern Jutland that its full name is often drømmekage fra Brovst — dream cake from Brovst. The usual story is that a young woman from Brovst entered her grandmother's recipe into a national baking competition run by a Danish flour or baking-powder brand in the 1960s, won, and the recipe then spread across the country through printed recipe leaflets and the brand's marketing. The details vary between tellings, but the Brovst connection is consistent and the cake's fame clearly dates from the post-war decades rather than any older tradition.

Coconut cake toppings of this kind were already part of mid-century Scandinavian baking, and similar 'toscakage'-style finishes — butter, sugar and something crunchy poured over a warm cake and returned to the oven — exist in Sweden and Norway too. What the Brovst recipe fixed in the Danish imagination was the specific combination: an airy, slightly plain sponge and a generous, dark, coconut-heavy caramel layer that is almost as deep as the cake beneath it.

Today drømmekage is a fixture of Danish birthdays, school bake sales, office coffee breaks (kaffe og kage) and the cake tins of grandparents. Bakeries and supermarket chains sell it in slabs, and it turns up on almost every list of classic Danish cakes alongside smultringer, æbleskiver and the cream-layered bløtkage.

In English it is sometimes mistaken for a Norwegian cake because the coconut topping resembles Norwegian formkake finishes, and sometimes confused with Swedish tosca cake, which uses flaked almonds rather than coconut. Drømmekage is specifically the Danish coconut version.

ii. Why the topping goes onto the hot cake

The whole character of drømmekage comes from a two-stage bake. The sponge is baked until it is just set and lightly golden, then the coconut topping — already cooked on the hob until the sugar has melted — is spread over it while both are hot, and the tin goes back into a hotter oven for a few minutes. That second spell is what turns a sweet coconut paste into a bubbling, glossy caramel crust.

The cake has to be set first because the topping is heavy. Pour a butter-sugar mixture onto raw batter and it sinks straight through, leaving a dense, greasy layer at the bottom and a cratered top. A sponge that has just set will carry the weight, and because it is still hot the topping stays fluid enough to spread evenly to the corners rather than tearing the surface.

Heat does the rest. Brown sugar and butter, with a little milk for body, reach a light caramel stage in the hot oven; the milk solids brown and the coconut toasts at the edges. Because the sugar is partly dissolved rather than crystalline, it cools to a chewy, fudge-like layer instead of a hard brittle, which is the texture Danes expect. Too little time and it stays wet and sticky; too long and the coconut scorches and the caramel turns bitter.

The sponge itself is deliberately simple: eggs and sugar whisked until pale and thick, then flour, baking powder and warm milk-and-butter stirred through. Whisking traps air for lift, and the warm liquid loosens the batter so it spreads evenly in a shallow tin. It should be light and a little plain, because the topping supplies all the richness.

• 3 eggs, at room temperature
• 300 g caster sugar
• 250 g plain flour
• 2½ tsp baking powder
• 2 tsp vanilla sugar or 1 tsp vanilla extract
• 200 ml whole milk
• 50 g butter, for the cake
• 125 g butter, for the topping
• 250 g light brown sugar
• 125 g desiccated coconut
• 60 ml whole milk, for the topping
• ¼ tsp salt

Use desiccated coconut, the fine, dry kind; sweetened flaked coconut holds more moisture and gives a soggier, sweeter topping. Light brown sugar is the standard Danish choice (farin); dark muscovado gives a deeper, more toffee-like crust but can overpower the coconut. Vanilla sugar is how most Danish recipes flavour the sponge — vanilla extract does the same job. A pinch of salt in the topping is not traditional everywhere but sharpens the caramel noticeably. Butter is essential in the topping; margarine was common in older recipes and works, but the flavour is flatter.

iv. Method

1. Heat the oven to 200 °C (400 °F), or 180 °C fan. Line a roughly 25 × 35 cm traybake tin with baking paper, letting it come up the sides.
2. Whisk the eggs and caster sugar with an electric mixer for 5–6 minutes until very pale, thick and doubled in volume; the mixture should fall from the beaters in a ribbon that sits on the surface for a few seconds.
3. Sift together the flour, baking powder and vanilla sugar and fold them gently into the egg mixture. Melt 50 g butter into the 200 ml milk until just warm, then stir it in until the batter is smooth and pourable.
4. Pour into the tin, level, and bake for 18–22 minutes until the sponge is golden, springs back when pressed and a skewer comes out clean.
5. While the cake bakes, melt the topping butter in a saucepan, add the brown sugar, coconut, milk and salt, and stir over a medium heat for 2–3 minutes until the sugar has melted and the mixture is glossy and just bubbling.
6. Take the cake out and spread the hot topping evenly over it, right to the corners, working gently so the surface does not tear.
7. Return the cake to the top half of the oven for 5–8 minutes until the topping is bubbling all over and has turned a deeper golden brown at the edges. Watch closely in the last two minutes; the coconut can catch quickly.
8. Cool in the tin on a rack for at least 30 minutes so the caramel firms, then lift out on the paper and cut into squares.

v. Tips & common mistakes

• Whisk the eggs and sugar properly. The sponge has very little butter and relies on whisked air for lightness. Stopping at 2 minutes gives a dense, flat cake that cannot carry the topping.
• Do not add the topping to an underbaked cake. If the centre is still wobbly, the heavy caramel will sink through and leave a wet, sunken middle. Test with a skewer first.
• Spread the topping while both are hot. A cooled topping turns stiff and will drag the surface of the sponge; a cooled sponge does not absorb the edge of the caramel, so the two layers separate when cut.
• Watch the second bake, not the timer. Ovens vary and the gap between deep golden and scorched coconut is about a minute. Look for bubbles across the whole surface, not just the edges.
• Use a tin of the right size. In a smaller, deeper tin the sponge takes longer to set and the topping becomes too thick to caramelise; in a much bigger one both layers are thin and dry.
• Cut with a hot, wet knife. The caramel layer is sticky; dipping the knife in hot water between cuts gives clean squares without dragging coconut through the sponge.

vi. Variations

Drømmekage in a round tin is common in smaller households and bakes in about the same time in a 24 cm springform. Chocolate drømmekage adds a few spoonfuls of cocoa to the sponge, while some bakers swap part of the coconut for chopped hazelnuts or flaked almonds, which brings it close to Swedish toscakaka. Modern Danish bakeries also sell drømmekage with a little cardamom in the sponge, a nod to the spice that runs through Nordic baking in things like the cardamom bun.

Its nearest relatives elsewhere are the coconut-topped traybakes of the wider world: the caramel-coconut layers of American seven layer bars, Australian lamingtons rolled in coconut, and German Bienenstich, which uses the same 'cook the topping, pour it on, bake again' logic with almonds and honey.

vii. Serving & storage

Drømmekage is served at room temperature, cut into generous squares, with coffee. It is a cake for afternoons, birthdays and gatherings rather than a plated dessert, though a spoonful of lightly whipped cream or vanilla ice cream alongside is never wrong. It is at its best a few hours after baking, once the caramel has set but before the sponge has started to firm.

Keep it covered at room temperature for up to 4 days; the topping softens slightly as it absorbs moisture from the sponge, which many people prefer. Refrigeration makes the caramel hard and the sponge dry. It freezes well: cut into squares, freeze on a tray, then bag, and thaw at room temperature for about an hour.
