Millionaire’s Salted Caramel Tart

Are you a fan of rich and indulgent desserts? If the answer is yes, then this Millionaire’s Salted Caramel Tart is the recipe for you!

The base of the tart is made using a shortbread dough, which is slightly different from traditional shortcrust. There’s no chilling, no kneading, no rolling or blind baking required, believe me when I say it’s as easy as pie to make! Once baked, the texture of the crust is very tender, almost like a shortbread cookie, which is a lovely nod to the classic millionaire’s traybake slice.

The shortbread crust is then filled with a layer of homemade salted caramel and topped with a layer of milk and dark chocolate ganache (I use both types of chocolate so it’s not too bitter). The final touches are a drizzle of salted caramel and sprinkle of sea salt flakes.

I was super happy to find a pot of Anglesey sea salt in the shops because it’s where my husband and I tied the knot last year! Millionaire’s salted caramel tart will now be another lovely reminder of our amazing wedding day.

Ingredients (makes a 9 inch tart / 10 slices)

For the shortbread crust:
200g plain flour
45 grams icing sugar
1/4 teaspoon salt
165g unsalted butter
3/4 teaspoon vanilla extract

For the salted caramel:
50g unsalted butter
50g light muscovado sugar
1 can (397g) of condensed milk
1/2 teaspoon salt

For the chocolate filling:
75g good quality 70% dark chocolate
75g good quality milk chocolate
25g butter
150ml double cream

Optional decoration:
Sea salt flakes

Method

Preheat oven to 180°C. Lightly grease a 8-inch tart tin (preferably with a removable bottom) with a bit of butter.

Start with the shortbread crust. Combine the flour, icing sugar, and salt in a small bowl and mix together. Melt the butter in a small saucepan (or in the microwave) until liquid. Pour into the dry ingredients and add the vanilla extract. Stir until all the ingredients come together to make a dough.

Press the dough evenly along the bottom and sides of the tart tin. Place the tart tin on a baking tray and bake for 15-18 minutes until golden brown. Remove and set aside to cool.

Now make the salted caramel. Heat the sugar and butter in a medium sized saucepan until melted. Pour in the condensed milk and bring to a rapid boil, stirring continuously for about 5 minutes until the mixture has thickened and is turns golden in colour. Stir in the salt and set aside to cool for 10 minutes.

Pour the salted caramel into the tart crust (saving 1-2 tablespoons to decorate with later) and spread it out into an even layer. Put the tart in the fridge to set.

Meanwhile, make the chocolate filling. Chop the chocolate and butter up into small pieces and place in a bowl. Pour the cream into a small saucepan and slowly bring to a boil on a low heat whilst stir occasionally. Once the cream has started to boil, pour it over the chopped chocolate and butter. Leave for 30 seconds and then slowly stir until everything has melted and the mixture is smooth.

Take the tart out of the fridge. Pour the chocolate filling on top of the caramel and spread it out into an even layer. Put the tart back in the fridge to set for two hours or overnight.

Now for the final touches! Drizzle the leftover caramel on top of the tart and sprinkle with sea salt. The tart is best served at room temperature and will keep in the fridge for up to 3 days.
