Pineapple Cake (Pacific) — Australian upside-down pineapple sponge

i. Origin & history

Upside-down cakes are an old idea — fruit cooked in butter and sugar in a skillet with batter poured over the top — but the pineapple version is a creature of the twentieth century and of the tin can. Once pineapple was canned in uniform rings on an industrial scale, first in Hawaii, a cake that showed off those perfect circles became a fashion. Pineapple upside-down cake spread across the United States in the 1920s and was carried around the English-speaking world by magazines, tinned-fruit advertising and community cookbooks.

In Australia it found unusually fertile ground. Queensland grows pineapples commercially and has had its own pineapple cannery since the mid-twentieth century, which made tinned rings a cheap pantry staple across the country. Pineapple upside-down cake became a standard of the Australian and New Zealand home kitchen and school cookbook, alongside lamingtons and Anzac biscuits — the sort of cake made on a Sunday afternoon for visitors or packed in a tin for a church supper.

Across the wider Pacific, where fresh pineapple is everyday fruit, similar cakes are baked with fresh slices and often with coconut in the batter. The 'Pacific' in this page's name reflects that shared tradition rather than a single island's recipe.

The name causes real confusion online. Taiwanese pineapple cake (fènglísū) is a completely different thing: a rectangular, buttery shortbread pastry filled with a dense pineapple — often pineapple-and-winter-melon — paste, sold in gift boxes. Some Malaysian and Singaporean pineapple tarts are similar. This page covers the Western-style upside-down cake.

ii. Why the caramel goes in the tin first

The topping is not added after baking; it is built in the bottom of the tin and the cake is baked on top of it. Melted butter and brown sugar are spread over the base, the pineapple rings are pressed into it, and the batter covers everything. In the oven, the butter and sugar melt and bubble with the pineapple's juices into a thin caramel, while the fruit's surface browns where it touches the hot metal. The cake above traps the steam, so the pineapple cooks through and turns soft and glossy rather than drying out.

Brown sugar is the right choice because its molasses gives caramel flavour without the need to take sugar to high temperatures on the stove, and it holds moisture so the topping stays soft and sticky instead of setting into brittle toffee. A little of the pineapple syrup from the tin added to the batter carries the fruit's flavour into the crumb.

Timing the turn-out is the step that decides success. Inverted straight from the oven, the caramel is too liquid and runs off the cake. Left too long, it sets and glues the fruit to the tin. Five minutes of resting is the sweet spot: the caramel is still molten but has thickened enough to cling.

A butter sponge rather than a light whisked sponge is used for structure: it must be sturdy enough to support a heavy layer of fruit when flipped, and dense enough to absorb some of the caramel without going soggy.

iii. Ingredients

Makes 10 servings · scroll the side panel to adjust

• 60 g butter, melted (topping)
• 80 g light brown sugar
• 7 tinned pineapple rings, drained, syrup reserved
• 7 glacé cherries
• 125 g unsalted butter, softened (cake)
• 150 g caster sugar
• 2 eggs, at room temperature
• 1 tsp vanilla extract
• 185 g self-raising flour
• 60 ml reserved pineapple syrup or juice
• 60 ml milk

A 440 g tin of pineapple rings in juice gives the rings and the syrup; pat the rings dry so they caramelise rather than stew. Fresh pineapple works beautifully — cut 1 cm rings and core them — but avoid using fresh pineapple juice in the batter with dairy for long, as its enzyme can make milk taste bitter. Glacé cherries in the centre of each ring are the retro Australian signature; omit them or use a pecan half if you prefer. Replace self-raising flour with plain flour and 2 tsp baking powder if needed. For a Pacific twist, swap 40 g of the flour for desiccated coconut and the milk for coconut milk.

iv. Method

1. Heat the oven to 180 °C (350 °F), or 160 °C fan. Use a 23 cm round cake tin that is not loose-bottomed — the caramel will leak from one. Grease the sides.
2. Pour the melted topping butter into the tin and tilt to cover the base. Sprinkle the brown sugar evenly over it. Arrange the dried pineapple rings in a single layer, one in the centre and six around it, and press a glacé cherry into the centre of each.
3. For the cake, cream the softened butter and caster sugar for 4–5 minutes until pale and fluffy. Beat in the eggs one at a time, then the vanilla.
4. Fold in half the flour, then the pineapple syrup and milk, then the remaining flour, mixing until just smooth.
5. Spoon the batter over the pineapple in dollops and spread gently to the edges without disturbing the fruit.
6. Bake for 40–45 minutes, until the cake is golden, springs back when pressed, and a skewer inserted into the sponge (not the fruit) comes out clean. The caramel should be bubbling at the edges.
7. Rest in the tin for 5 minutes only. Run a knife round the edge, place a serving plate upside down over the tin, and invert in one confident movement. Lift the tin away; if any fruit sticks, nudge it back into place and spoon over any caramel left in the tin.
8. Serve warm or at room temperature.

v. Tips & common mistakes

• Dry the pineapple rings. Wet fruit leaks juice into the caramel, which then never thickens and the top of the cake turns soggy.
• Do not use a springform or loose-base tin. The melted butter and sugar will seep out, burn on the oven floor and leave the topping dry.
• Turn it out after five minutes. Sooner and the caramel runs everywhere; much later and it sets, gluing the fruit to the tin. If it does stick, warm the base of the tin over low heat for a minute.
• Test the sponge, not the fruit. A skewer through the pineapple will always come out sticky. Push it into a gap between rings.
• Keep the topping layer thin. More butter and sugar sounds generous but gives a greasy, sliding topping; the amounts here are enough for a glossy coating.
• Serve within a day for best texture. Over time the caramel soaks into the sponge and the top loses its shine.

vi. Variations

Pineapple and coconut cake adds desiccated coconut and coconut milk to the batter for a tropical, Pacific-island feel. Individual upside-down cakes are baked in muffin tins with pineapple pieces. Pineapple upside-down pudding, a richer, softer self-saucing version, is served hot with custard in winter. In the American South the cake is often made in a cast-iron skillet, and in many households pecans sit in the gaps between rings.

The same pineapple-and-caramel idea turns up in our pineapple upside-down brownie and in tarts such as the pineapple coconut tart. Other caramelised-fruit desserts include the French tarte Tatin family and the flambéed bananas Foster. Pineapple tarts belong instead to the festive cookie jars of Malaysia and Singapore, where they sit beside melt-in-the-mouth kue bangkit at Chinese New Year.

vii. Serving & storage

Pineapple upside-down cake is at its best slightly warm, when the caramel is soft and the sponge tender, with a jug of custard, a scoop of vanilla ice cream or thick cream. At room temperature it is an afternoon-tea cake, cut into wedges and eaten with a fork.

Keep it covered at room temperature for up to 2 days, or in the fridge for up to 4 days in hot weather; bring it back to room temperature or warm slices briefly in the microwave or a low oven before serving. The cake freezes reasonably well in individual slices for up to a month, though the pineapple softens on thawing. It is not a make-ahead cake in the strict sense — the topping looks best within a few hours of turning out — but the batter and topping can be weighed out in advance.
