Preheat oven to 160°C.
In a bowl, mix together maida, powdered sugar, milk powder, baking powder and baking soda.
Add melted butter, milk and rose essence.
Mix to form smooth batter.
Add grated coconut and fold in the batter.
Pour the batter into a 5" square tin which is greased and lined with parchment.
Bake in preheated oven for 30-40 minutes or until a tooth pick inserted comes out clean.
Let the cake cool for five minutes on the rack.
Flip it onto the wire rack, remove the parchment and flip it back so that the top of the cake remains on the top.
Allow it to cool completely.
Slice it up and serve.
