Hmm... I tried a Google search... about 90% of the hits I got for "buttercream crunch" were for scented candles.
For ' "Buttercream Crunch" Recipe ' I got another bunch of candles and the second hit on the first page was this thread.
I have a feeling this might be a difficult find.
Into the fires of forever, we will fly through the heavens, With the power of the universe we stand strong together
Through the forcing of power, we will soon reach the hour, For victory we ride, Fury of the Storm!
