For the cake

  • ½ tbsp desiccated (unsweetened dried shredded) coconut
  • 1 medium egg, separated
  • 2 tbsp butter, softened
  • 50g (1.8oz / approx. ¼ cup) fresh pineapple, finely chopped
  • 1 tsp rum flavouring, see notes
  • 3 tbsp caster (superfine) sugar
  • 2 tbsp coconut milk
  • 1 tsp vanilla extract
  • pinch of salt
  • 5 tbsp self-raising flour


  • 2 tbsp double (heavy) cream
  • ½ tbsp icing (confectioners') sugar, sifted
  • 1 tsp rum flavouring, see notes


  • ½ tbsp coconut flakes, toasted
  • 1 glace cherry
  • pineapple wedge
  • 1 cocktail umbrella, optional


  1. To make the mug cake, tip the desiccated coconut onto a small plate and spread out. Take a 350ml (approx. 1½ cups sized) mug and dip the rim of the mug into the egg white, then immediately into the desiccated coconut.
  2. Next, add the butter, pineapple, rum flavouring and caster sugar into the mug and microwave for 1 minute. Allow to cool slightly.
  3. Add the remaining egg white, egg yolk, coconut milk and vanilla and beat with a fork until just combined.
  4. Add the flour and salt and beat again until smooth.
  5. Cook in the microwave for 3 minutes 30 seconds at 1000W or 4 minutes 30 seconds for 800W. Allow to cool completely.
  6. Meanwhile, to make the icing, in another clean mug, add the cream, icing (confectioners') sugar and rum flavouring and beat together with a fork until light and fluffy.
  7. Once the mug cake has cooled, spread the icing over the cake with the back of a spoon.
  8. Garnish by sprinkling on the toasted coconut onto the icing, then add the glace cherry, pineapple wedge and cocktail umbrella.
