I've seen recipes using Oreo biscuits on YouTube, where the biscuits are dunked in some sort of coffee/alcoholic brew, then sandwiched together with some creamy confection. Sort of Tiramisu with Oreos. Looks nice, I would eat it if offered probably. If you want to make it I'll come along and test it for you.
I made something similar with a different type of biscuit (can't remember which ones).
Make strong black coffee, add coffee liqueur, dunk biscuits quickly, cover in a mixture of whipped cream and mascarpone, with a little icing sugar if you wish. This was placed on a plate like a Swiss roll but you could put it in a dish like a tiramisu.
