170g cold butter, cubed, plus a little for the tin
75g golden caster sugar
397g can of condensed milk
2 tbsp golden syrup
2 tbsp dark brown sugar
3 passion fruits, pulp only
200g dark chocolate
30g coconut shavings, toasted
Heat oven to 180C/160C fan/gas 4 and butter a 23 x 23cm brownie tin. First, make the shortbread by stirring the flour and coconut together in a bowl, then rub in the butter with your fingers until the mixture looks like breadcrumbs. Stir through the sugar, then bring the dough together with your hands. Pat into the tin, pricking the top all over with a fork. Bake for 15-18 mins until lightly golden and crisp.
For the caramel, put the butter, condensed milk and syrup in a pan with a large pinch of salt. Heat gently until simmering, then whisk for 6 mins until thick and fudgy. Take off the heat and stir in the passion fruit pulp. Pour over the shortbread, smooth over with a palette knife and leave to set.
Once set, melt the chocolate in the microwave in 30-second bursts until glossy and smooth. Smooth over the caramel shortbread, then scatter over the coconut shavings. Leave to set, then cut into 16 squares. Will keep for five days in an airtight container.
