Bake cupcakes per recipe on box and cool completely.
In a bowl mix white frosting with yellow food color to make a deep yellow color. If you are making multiple colors you can divide the icing into bowls and mix them up separately!
Place a small dab of frosting directly in the center of the cupcake and place the mini Oreo on top.
Pipe petals from the cookie outward all the way around the cupcake.
Serve and enjoy.
