I am not sure what nut creams you are referring to... Without cream I assume?
And Steve, thanks. What is a Biscuit besides being a cookie?!
A "biscuit" in this usage is a long, generally flat tool used for spreading another substance into a uniform layer. A cursory search for a dictionary definition turned up nothing useful.
On the subject of "nut creams", would a gianduja be a good first order approximation of what is being looked for? Depending on the final texture needed, additional ingredients could be added to thin the mixture or keep a softer texture (gianduja will harden in a short time).
