Grease a microwave cake ring (or a round or heart-shaped microwave cake dish). Mix the dry ingredients in a large mixing bowl. In a separate bowl, whisk the eggs, oil and vanilla essence, and slowly add the boiling water, mixing as you pour it in. Add this mixture to the dry ingredients and mix gently to combine.
Pour into the cake ring and microwave on High for 6 minutes. Allow to cool while you make the icing.
To make the icing, mix the ingredients until smooth, altering the quantities to suit your preferred consistency. Ice the cake and serve as soon as possible.
