  • 1tsp vanilla extract, good quality
  • 250g icing sugar, sifted


  • Melt the chocolate in a bowl or plastic jug in the microwave until smooth and a thick pouring consistency. A general guide would be to heat at 30 secs intervals on medium, stirring in between, to avoid burning the chocolate. Leave to cool slightly.

  • Beat the butter, sugar, milk and vanilla with an electric hand beater in a bowl until smooth. Add the melted chocolate and beat until thick and creamy. Top your cake or cupcakes.

Top tip for making Chocolate buttercream icing

If the buttercream looks too runny to use when trying to ice cupcakes or cakes, simply keep beating, this will thicken the icing and improve its consistency.
