California Apricot Upside-Down Cake

a Santa Clara Valley summer cake: ripe fresh apricot halves caramelised in brown butter and brown sugar beneath a golden almond-scented buttermilk sponge, turned out to reveal the glistening caramel apricot crown

Origin: Santa Clara Valley, California, United States

From the journey of Apricot.

The apricot was one of the first orchard crops to define the Santa Clara Valley of northern California, introduced by Spanish Franciscan missionaries from the Baja California missions in the 1790s and planted in earnest in the mission orchards at San José and Santa Clara. By the 1880s the valley floor was a continuous apricot orchard (one hundred thousand acres known as the Valley of Heart's Delight) and California had become the world's dominant commercial apricot producer, drying the surplus on vast wooden trays in the summer sun and shipping it east and to Europe. The domestic cooking tradition that grew up around the California apricot drew on the Spanish mission heritage, the Yankee New England baking culture of the settlers, and the later Italian and Portuguese immigrant influence in the orchard communities, all of which combined into a distinctly Californian approach to fruit-centred baking: straightforward, generous, and led by the quality of the fruit rather than by elaborate technique. The apricot upside-down cake is the California home baker's answer to the Provençal tarte: a simple caramel-topped sponge that can be made and inverted in a single skillet, showing the caramelised apricot crown when turned out. The buttermilk in the sponge echoes the slight tartness of the apricot; the almond extract amplifies the kernel note that defines the fruit. It is, at its best, a monument to a single perfect summer apricot.

Ingredients

Fruit

700 g ripe but firm fresh apricots (approximately 10–12), halved and stoned

Caramel

60 g unsalted butter
120 g soft light brown sugar

Sponge

160 g plain flour
1 tsp baking powder
0.25 tsp bicarbonate of soda
0.25 tsp fine salt
120 g unsalted butter, softened
180 g caster sugar
2 large eggs
1 tsp vanilla extract
0.5 tsp almond extract
160 ml buttermilk, at room temperature

Method

Preheat the oven to 180°C / 160°C fan. In a 25 cm ovenproof skillet or heavy round cake tin, melt the 60 g butter over medium heat until it begins to brown and smell nutty. Add the brown sugar and stir until melted and bubbling. Remove from the heat.
Arrange the apricot halves cut side down in the caramel in the skillet, packing them tightly in a single overlapping layer. Set aside.
Whisk together the flour, baking powder, bicarbonate of soda, and salt in a bowl. In a large bowl, beat the softened butter and caster sugar until very pale and fluffy, about 4 minutes. Beat in the eggs one at a time, then the vanilla and almond extracts.
Fold in the flour mixture in three additions, alternating with the buttermilk in two additions, beginning and ending with the flour. Mix only until just combined; do not overbeat.
Spoon the batter carefully over the apricots in the skillet, spreading it gently to the edges without disturbing the fruit. Bake for 35–40 minutes until the sponge is golden, set in the centre, and a skewer inserted into the middle comes out clean.
Remove from the oven and allow to cool in the tin for exactly 10 minutes — no longer. Run a knife around the edge, place a serving plate firmly over the skillet, and invert in one confident motion. Leave the tin in place for 1 minute to allow the caramel to settle onto the surface, then lift carefully.

Notes

The almond extract is essential, not optional: it amplifies the apricot's kernel note in a way that vanilla alone cannot, and it is the specific flavour memory of the California stone-fruit baking tradition. Very ripe apricots release more juice during baking and can make the caramel slightly loose; firm-ripe apricots are better here for a cleaner caramel layer. If any apricots stick to the pan on inversion, lift them off gently with a palette knife and press them back into place: the caramel will have set enough to hold them. Serve warm with a generous spoonful of crème fraîche or vanilla ice cream.
