I’m disappointed, frankly. I don’t have any Oreos on hand to experiment with, but I’m fairly certain there’s a delicious (and, yes, deadly) concoction to be had in a buttered Oreo.
I googled to see if anyone else has tried this and reported on their results. First, I found one result (that wasn’t prefaced with "peanut" — I don’t want to know about peanut buttering an Oreo), and it was clearly concatenating the lines.
Then I tried the past tense, in case somebody related a story about it – no results.
Then I thought, maybe the Oreo would merit a definite article. If it’s an experiment, you’d probably use a singular, particular cookie. Still nothing, however.
If you, dear reader, have Oreos on hand, will you please, for the sake of science, try buttering* an Oreo? The world awaits your findings.
*If all you have is margarine, don’t bother. Nobody cares about your dumb margarine-Oreo experiment.
