Method

• 1.
  Preheat oven to 180°C and line 10 holes of a muffin pan with paper cases.
• 2.
  Sift the flour, sugar, cocoa, baking powder and 1/2 teaspoon of salt in a bowl.
• 3.
  Whisk buttermilk, egg, oil and vanilla in a separate bowl. Use a spatula to fold into dry ingredients until well combined.
• 4.
  Spoon batter into muffin cases. Bake for 25 minutes until a skewer inserted in the centre comes out clean. Cool slightly, then transfer to a rack to cool completely.
• 5.
  Meanwhile, for the icing, beat the sugar, butter and milk in a processor or electric mixer until soft. Add the food colouring a few drops at a time until you reach the desired colour.

• 6.
  Roll out black icing on a sheet of baking paper and use a small cutter to make decorative shapes (we used a cat, and pressed in cachous to make eyes).
• 7.
  Spread orange icing over cakes, then decorate with icing shapes.
