Guinness mug cake

step by step

  • 1Place the butter and chocolate in a 350ml microwaveable mug and microwave for 10-20 seconds until melted.
  • 2Add the egg to the mug and beat with a fork until combined. Stir through the Guinness, then add the sugar, flour and a pinch of salt and beat again until smooth.
  • 3Cook in the microwave for 2 minutes at 600W, 1 minute 45 seconds at 800W or 1 minute 30 seconds at 1000W. Leave to cool.
  • 4Meanwhile, make the icing. Beat the icing sugar and cream cheese together until smooth, then spread over the cooled cake, swirling with the back of a spoon. Scatter with the sprinkles to serve.
  • It's important to use a microwave-safe mug, otherwise the mug can crack.
