Bake cupcakes as usual and make a batch of frosting of your choice.
Cut mini marshmallows on the diagonal
Dip the cut side of the marshmallow pieces into colored sugar
Frost one cooled cupcake (I frost and decorate one at a time so that the frosting is soft)
Carefully arrange the dipped pieces on the frosting to make petals
Fill the whole top with petals or leave a little circle to sprinkle the center with little pearls or jimmies or other sprinkles of your choice. or Ballerinas. Ballerinas are always good.
