Preheat oven to 180°C. Prepare a 15cm cake tin & a 25cm cake tin.
Sponge Base : Mix egg, Chelsea White Sugar, cornflour and the gluten free baking powder. Add vanilla essence to the mixture. Pour the sponge mixture into the prepare cake tins.
Place in the oven to bake for 12 to 15 minutes, or until the base has risen and turned golden.
Set aside to cool. Raspberry Curd
Melt the butter in a large saucepan over medium heat. Add the raspberries, egg yolks, Chelsea White Sugar, and salt and cook, mashing the berries and stirring frequently at first and them constantly at the end, until thickened, about 10 minutes.
Pour the mixture through a coarse strainer set over a bowl, pressing hard on the solids to extract as much liquid as possible. Cool to room temperature; the curd will continue to thicken as it cools. Stir in lemon juice to taste and place in the fridge to cool.
Lemon Curd : Melt the butter in a large saucepan over medium heat. Add eggs, Chelsea White Sugar, lemon zest and lemon juice, then stir over low heat until thickened.
Filling : Split the vanilla pod in half lengthways and scrape out the seeds. Put the vanilla seeds, lemon zest, lemon juice, Chelsea Caster Sugar, cornflour and cream cheese into a bowl and whisk together. Add eggs, one at a time, beating well between each one. Add the double cream, whisking until the mixture is smooth.
Pour just over half the mixture into the larger cake tin and swirl through lemon curd. Tap lightly to settle the mix.
Add 250g of the raspberries to the remaining mixture and stir carefully through the mixture.
Pour this into the smaller cake tin and tap lightly into the mix.
Put the cake tins into a roasting tray, then pour hot water into the tray to a depth of 2cm to create a Bain Marie. Bake in the oven for 75 to 90 minutes, or the tops are golden and the cakes just set.
Remove from the oven and allow to cool in the tins. Remove from tins and place on a serving plate then top with the remaining raspberries and drizzle over Chelsea Maple Flavoured Syrup.
Garnish with raspberry curd, lemon curd and fresh berries to serve.
