Heat the oven to 180C/160C fan/gas 4. Butter a 30 x 20 x 4cm baking dish. Put the eggs, extra yolks, sugar, milk, cream, 200g of the caramel, the vanilla and a large pinch of sea salt in a large bowl, then whisk until combined. Stir in the flour until the batter is smooth.

Halve, core and cut the apples into 1cm slices – there’s no need to peel them. Arrange in the baking dish and pour over the batter. Bake for 30-35 mins until the batter is set in the centre, golden and slightly risen.

Drizzle over the remaining caramel, then sprinkle with a little extra sea salt. Leave to rest for 5-10 mins (it will deflate a little). Serve warm with vanilla or peanut butter ice cream, if you like.
