Make the Galaxy chocolate ganache and fill the cupcakes

  • Finely chop the Galaxy chocolate (the smaller the chunks the better) and place in a glass bowl.
  • Heat the cream in a small saucepan set over low heat until it's piping hot, but not yet boiling.
  • Pour the hot cream over the chocolate and leave to sit for 20 seconds. Now slowly stir until the chocolate melts and the ganache is smooth.
  • Once the cupcakes have cooled, scoop out the middle of each using a cupcake corer, the base of a piping nozzle or a teaspoon.
