Bring a little flower power to your next gathering with this cute DIY cupcake decorating idea. To make these treats, cut mini marshmallows in half on the diagonal—these will be your petals. Dip the cut side of each marshmallow into purple-coloured sugar. Ice the cupcakes with white icing, then press three purple licorice pellets into the centre of each cupcake. Working from the inside out, carefully place the marshmallow petals around the licorice, with pointed edges facing out.
