Sheet-pan plum cake

A plain butter sponge under a whole tray of plums. It is better on the second day, if it lasts that long.

Ingredients

• 1.2 kg small plums, halved and stoned
• 250 g soft butter
• 200 g sugar, plus 2 tbsp for the top
• 4 eggs
• 350 g plain flour, 2 tsp baking powder, a pinch of salt
• 150 ml milk
• ½ tsp ground cinnamon

Method

1. Heat the oven to 180 °C and line a 30 × 40 cm tray with baking paper.
2. Beat the butter and sugar until pale, then the eggs one at a time.
3. Fold in the flour, baking powder and salt, alternating with the milk, to a soft batter. Spread it in the tray.
4. Press the plums in closely, cut side up. Mix the extra sugar with the cinnamon and sprinkle over.
5. Bake for 40–45 minutes, until a skewer comes out clean between the plums. Cool in the tray.
