Oreo Sippers were hollow, Oreo-flavored wafer sticks designed to be eaten as a snack or used as a straw for drinking milk, popular in the 2000s but discontinued by Nabisco around 2012, leaving fans nostalgic for the unique, milk-absorbing cookie straw. Despite petitions and requests for their return, Nabisco hasn't brought them back, though similar wafer roll products exist in other markets, notes a Yahoo article.

What They Were:

Description: Cylindrical, hollowed-out wafer cookies with the classic Oreo flavor.

Function: Could be eaten plain or dipped in milk, acting as a cookie straw.

Appeal: A fun, innovative snack that combined the Oreo experience with a beverage, fitting into the late '90s/early 2000s trend of cereal straws and yogurt tubes.

Why They Were Discontinued: Nabisco never issued a formal public statement, but they phased out around 2012. Reasons likely included declining sales or a shift in company strategy, as similar products from other brands also faded, according to a Reddit post. While beloved by many, they might not have generated enough profit for Nabisco to continue, suggests a Reddit thread.
