1. Preheat oven to 180C or fan forced 160C
2. Sift flour and baking powder together.
3. Grease a 20 cm x 30 cm / 8" x 12" cake pan. Line with baking paper (parchment paper), leaving an overhang on all sides (to make it easy to remove).
4. Beat butter, sugar and vanilla with an electric mixer on medium high speed until light and fluffy - about 1 1/2 to 2 minutes.
5. Add eggs 1 at a time, beating well after each addition so the batter is smooth, not curdled
6. Add half the flour and gently fold to combine, then stir in half the milk. Repeat with remaining flour and milk.
7. Pour the batter into the prepared pan and bake for 25 minutes until a skewer inserted into the centre comes out clean
8. Stand for 5 minutes then use the overhang baking paper to lift the cake out onto a wire rack and cool completely.
9. cut into pieces and freeze for 1 hour just prior to coating.
10. Combine the Icing ingredients in a heat proof bowl and mix until smooth. Should be a syrup consistency, but not watery.
11. Place coconut in a shallow bowl or pan with a largish surface area
12. Place a piece of cake in the icing and roll to coat using 2 forks. Transfer it into the coconut and quickly roll to coat all over in coconut. Transfer to tray.
13. Repeat with remaining sponges.
14. Stand for 1 to 2 hours, or until set. Then serve with tea and coffee!
