It could be crowned the great cookie controversy of the century.

Teacher Dan Anderson and his students were investigating the properties of the beloved Double Stuf Oreo cookie when they reached a shocking revelation - the stuffing is not actually double.

"They eventually found out that it looks like the stuffing in the Double Stuf is only about 1.9 times the stuffing," Anderson told Fox News' Shepard Smith on Studio B.

"That's not double," Smith said. "You know what double means? Double 10 is 20. Double 400 is 800. Double Stuf is less than double."

A spokesman for the creme-filled cookie responded to the conundrum.

"While I'm not familiar with what was done in the classroom setting, I can confirm for you that our recipe for the Oreo Double Stuf Cookie has double the Stuf, or creme filling, when compared with our base, or original Oreo cookie," said Kimberley Fontes of Mondelez Global LLC.

But Shep has advice for those who feel cheated by the Double Stuf duplicity.

"Well, you see, when I was a child they didn't have Double Stuf. So what you would do is, you would just eat the center out of all of them and then this part goes back behind the couch. And when we moved into Nana's house in 1978, they might've found them," Smith said. "But if you eat two of them, you have eaten double the filling. But if you eat a Double Stuf, you have not."
