Cake by MaryKay C., Kiev, Ukraine

Bake per box instructions.  (I used white cake mix and stirred in four tablespoons of red/white/blue decorating sprinkles as cup cake decorations.)  Make butter cream icing and tint 1/3 royal blue/, 1/3 white, and 1/3 red. 

Using decorator # 33, pull out blue "fireworks" around outside edge.  Then do a circle of white.  Finish with red center.  Stick mini flags in the center. 

This is from Wilton, very easy to do.
