@Butrflynet,
That's an interesting idea!
I used ground up Oreos to make garden paths on a cake for Mo one year (with hand painted marzipan vegetables (it was a pretty cake, if I do say so myself).
I would need to find a way to stencil it to the frosting.....
I have test cakes in the oven! I ended up using springform pans instead of an angel food pan so I could cut out the centers and use them for test frostings, while freezing the big circle for later on the actual cake (if the recipe turns out good, that is).
I going to test my "spatter" ingredients in a bit to see if I can make good python spots.
