Grease and line a 20cm x 30cm (8" x 12") baking tin (leaving extra overhanging the sides) and set aside (see my notes for alternatives).
Melt sweetened condensed milk and salted butter together in the microwave then mix to combine.
200 g sweetened condensed milk, 150 g salted butter
Add chopped dried apricots, crushed biscuits, desiccated coconut and vanilla and mix until combined.
250 g plain sweet biscuits - I used Arnott's Marie, 225 g dried apricots, 85 g desiccated coconut, 1 teaspoon vanilla
Tip base mixture into a greased and lined tin and press down well to compact (the base of a glass works well for this).
Sprinkle with extra desiccated coconut and place in the fridge to set.
