Added finely crushed Oreos to my regular buttercream frosting(scraped out Oreo frosting- too sweet)- was a nice, stiff frosting to frost with- loved working with it- had only used for cupcakes before. Son's "graduation" from preschool and wanted something with the Batman symbol on it. "watch out kindergarten- here comes Colin" is what it says- you'd have to know him to understand. Took very little time to finish and I had fun making it.
