Had these recently at a BBQ. YUM! I have not yet made them myself, but they were made with Sunbutter and omitted the peanuts, and were very good. They were safe for dd. :) She loved them.

I might try this. I wonder if crushed almonds would be strange where peanuts are called for.
I think almonds are a pretty neutral flavored nut. But maybe you could also use almond butter. I have sometimes used pretzels where nuts were called for and as long as you eat it within a few days, they work pretty will for the crunch factor.
