Cake mix & baking
Place the baking mixture in a bowl, add the butter, eggs and milk and mix well. Spread the mix over the prepared oven tray.
Bake for approx. 20 mins. in the centre of an oven preheated to 180°C. Remove the cake, allow to cool a little, and turn onto a fresh sheet of baking paper. Remove the top sheet of baking paper and return the cake to the oven tray.
Combine the icing sugar with all the ingredients up to and including coffee, stir well and spread over the cake, scatter with the coconut flakes and leave to cool. Cut the cake into 20 slices.
