To decorate the cupcakes use a piping bag with a large star nozzle, fill 2/3 with buttercream/icing, making sure the top of the bag is secured (with a freezer clip).
Start piping from the outer edge of the cupcake and slowly work your way round overlapping the layers as you reach the centre of your cupcake. Make sure you apply even pressure to your piping bag as this insures an even swirl all the way around. Stop squeezing as you pull away from the centre of the swirl to create a nice pointed top a bit like an ice cream. To finish up, decorate each cupcake with a single Cake Daffodil.
