What did the discontinued chocolate fudge sandwich cookie look like?

You're probably thinking of the Oreo Fudge Covered Sandwich Cookies, which were discontinued in 2012.

They looked like regular Oreo cookies, but with a thick layer of chocolate fudge covering the entire cookie, instead of the usual frosting. The chocolate fudge was a dark brown color and had a smooth, glossy finish.

Here are some additional details:

* Shape: The cookies themselves were the standard Oreo rectangular shape.

* Size: The cookies were slightly larger than the traditional Oreos, to accommodate the extra fudge.

* Texture: The fudge was smooth and creamy, but also slightly chewy.

Unfortunately, they are no longer available, but there are some similar alternatives available like the Oreo Double Stuf Fudge Covered Sandwich Cookies.
