    He skips the part about how to cover up the hole with the candies inside! It goes into the fridge with a hole at the top in video 4, then it comes out of the fridge completely iced over at the start of video 5. Do you just layer icing over the candies and smooth it out?

      Hello Ryan, Sorry it seems to have been missed out…. As soon as the cake has chilled you want to spread the buttercream over the top, make it smooth then pop back in the fridge to set. 10 to 20 mins later you can then move on with the tutorial. Once again sorry about this part being missed out.
      Kind regards
