SHORTBREAD

200g cold butter
cubed plus more for the tin
275g plain flour
100g caster sugar

CARAMEL

397g can condensed milk
150g soft light brown sugar
150g butter
½ tsp sea salt flakes
plus a pinch

Method

step 1
Heat the oven to 180C/fan 160C/gas 4. Grease and line a 20cm brownie or square tin. Put the flour, sugar and butter in a food processor and pulse until it forms a dough. Press the dough into the base of the tin, and press into the corners with your fingertips. Prick with a fork and bake for 20 minutes until golden and dry. Leave to cool.
step 2
Put the caramel ingredients in a small pan over a medium low heat and cook, continually whisking for 2-3 minutes until the sugar has melted. Cook whisking for a further 6 minutes until thickened. Pour over the cooled shortbread, smooth over, cool to room temperature, and chill until set (about 2 hours). You can freeze to speed this up if you like.
step 3
Melt the chocolate in the microwave or in a heatproof bowl over a pan of simmering water until smooth and glossy. Leave to cool slightly, then pour over the set caramel. Cool again until set. Sprinkle with a pinch more salt and cut into squares with a hot knife to easily go through the chocolate. Best stored in fridge for up to 3 days.
