250 gm caster sugar
250 gm plain flour
30 gm unsalted butter, melted
400 gm shredded coconut
Chocolate ganache coating
600 gm dark chocolate, coarsely chopped
300 ml pouring cream
Preheat oven to 190C. Whisk eggs and sugar in a heatproof bowl over a saucepan of gently simmering water for 5-10 minutes or until warm (about 40C), pale and frothy. Transfer to an electric mixer and whisk on high speed for 10 minutes or until mixture has tripled in volume. Sift over plain flour in batches, folding gently to combine between additions. Just before adding the last of the flour, fold through melted butter. Divide batter between 2 lightly greased and base-lined 20cm square cake pans. Bake in centre of oven for 20 minutes or until a skewer comes out clean. Stand in pans on wire racks for 10 minutes, then turn out onto racks and cool completely.
For chocolate ganache coating, combine chocolate and cream in a heatproof bowl over a saucepan of gently simmering water. When chocolate begins to melt, stir gently until combined and smooth and set aside in a warm place.
Scatter shredded coconut over a tray. Cut each sponge into sixteen 5cm squares. Using 2 forks, dip each square into the chocolate and shake to remove excess. (If chocolate starts to thicken, place bowl over gently simmering water to thin.) Roll each square in coconut, shake off excess and place on a wire rack (sitting over a tray). Stand for at least 1 hour or until chocolate sets
