METHOD

1. Preheat oven to 180°C (350°F). Place the butter, sugar and vanilla in the bowl of an electric mixer and beat for 8 minutes or until pale. Add the eggs, one at a time, beating well after each addition. 
2. Add the flour, baking powder and desiccated coconut and mix to combine. Gradually add the buttermilk and beat on low speed to combine. Spoon into a lightly greased 20cm x 30cm tin lined with non-stick baking paper. 
3. Smooth with a palette knife and bake for 25–30 minutes or until golden brown. Set aside for 10 minutes to cool in the tin before transferring to a wire rack to cool completely. 
   
4. Place the chocolate and cream in a small saucepan over low heat and cook, stirring constantly, for 2–3 minutes or until melted and smooth. Cut the sponge in half and top one half with the chocolate mixture. 
   
5. Sandwich with the remaining sponge and cut into 12 squares. To make the icing, place the icing sugar, cocoa powder, water and butter in a large bowl and whisk to combine. Place the shredded coconut on a tray. Using a fork, dip 1 lamington in the icing and roll in the shredded coconut. 
   
6. Place on a wire rack or tray to set. Repeat with remaining lamingtons. Serve. Makes 12.
