  • 758 calories / serving

Ingredients

For the cake

  • 20g unsalted butter, plus a little extra for greasing
  • 30g dark chocolate
  • 2 tbsp caster sugar
  • 1 medium egg, lightly beaten
  • 2 tbsp self-raising flour
  • ½ tsp instant coffee granules, dissolved in 2 tsp boiling water
  • ½ Conference pear, peeled, cored and cut into pieces
  • ½ tsp icing sugar

For the decoration

  • 1 tbsp milk chocolate sprinkles
  • red writing icing
  • 8 green M&M’s
  • 2 liquorice twists
  • 24 mini marshmallows

Method:

  1. Put the butter and chocolate in a heatproof bowl. Microwave for 45 secs-1 min on medium until melted. Add the caster sugar, egg, flour and coffee and whisk until just combined. Grease the base of a 300ml, straight-sided microwave-proof mug and put the pear in the bottom. Top with the cake mixture. Cook for 2 mins on high until risen.
  2. Leave the cake in the mug to rest for 10 secs, then turn out cool for 10 mins, then scatter each with 1 tbsp milk chocolate sprinkles. Poke holes for the eyes, then squeeze a little red writing icing onto 2 green M&M’s and push into the holes. Use icing for pupils.
  3. For the bolts, poke holes either side and push in half a liquorice twist. Use red writing icing to stick on 6 mini marshmallows in a row to make teeth. Draw around them to create lips, then draw on some stitches too.
