Instructions
1
Prepare the oven
Preheat the oven to 180°C (th. 6). Line a 33 x 23 cm Swiss roll tin with baking paper and lightly grease.
2
Make the dough
Place the flour and sugar in a bowl, add the butter and rub in with your fingers until the mixture resembles breadcrumbs. Knead into a dough.
3
Bake the base
Press the dough into the prepared tin and flatten the surface with the back of a tablespoon. Prick a few holes across the surface with the tines of a fork. Bake in the oven for 20 minutes, until the dough feels firm and starts to turn golden. Cool in the tin.
4
Make the caramel filling
Place the butter, mascarpone, and sweetened condensed milk in a saucepan. Melt over low heat, stirring. Once it comes to a boil, reduce the heat and stir continuously for 5 to 10 minutes, until the mixture begins to caramelize. Be careful not to let it burn, or the flavor will be ruined. Remove from the heat.
5
Add the filling
Pour the mixture over the base, smooth the surface, and let it cool.
6
Decorate
Melt the three chocolates separately over a bain-marie or in the microwave. Drizzle lines of dark chocolate and milk chocolate over the caramel filling.
7
Create the marble effect
Add a small spoonful of white chocolate and use a fork to drag it across the surface, creating a marble pattern.
