1 cup plain flour, sifted
½ cup brown sugar
½ cup desiccated coconut
125g butter, melted, plus 60g extra
395g can sweetened condensed milk
2 tablespoons maple syrup
200g dark chocolate, chopped
2 teaspoons vegetable oil
Preheat oven to moderate, 180°C. Lightly grease an 18cm x 28cm slice pan. Line base and sides with baking paper.
In a bowl, combine flour, sugar and coconut. Make a well in centre. Add melted butter and mix well.
Press mixture firmly into pan with a fork. Bake 15-20 minutes, until lightly browned. Cool.
Combine extra butter, condensed milk and syrup in a medium saucepan. Stir over low heat until smooth. Pour over base. Bake 15-20 minutes, until golden. Cool.
Place chocolate and oil together in a heatproof bowl. Stir over a saucepan of simmering water 4-5 minutes, until melted and smooth (see tip).
Pour chocolate evenly over slice. Chill until set. Cut into squares. Store in an airtight container in the fridge.
