Back in June, Brownie Batter Oreos were coming our way, and today, Aug. 10, the sweet treat officially goes on sale nationwide. We're delighted to reveal that these cookies are delicious. The feedback was pretty consistent: these really do taste like brownie batter. The best part? You don't even have to wait, because the latest flavor is hitting store shelves today. Brownie Batter Oreos will only be available while supplies last.

An Oreo spokesperson told R29 that this typically means six to eight weeks for the brand's limited-time only flavors.The cookies win immediate points for being chocolate on chocolate, as well as turning our favorite guilty pleasure (eating brownie mixture before we actually commit to baking it) into a treat that can't give us salmonella.

The new Oreos feature the classic chocolate cookie outside, with brownie batter-flavored chocolate creme on the inside. We would continue to gush about the new Oreo flavor, but you'll have to excuse us because we need to make a very important trip to the supermarket to, ahem, stock up.

In April 2011, Oreo announced its special edition Oreo cookies with blue creme in promotion of the 2011 3D computer animated film Rio. The promotion included stickers inside each package of cookies. Two types of contests were also announced: first, by completing an album of stickers, consumers could win three movie passes and medium snack bar combos; second, by finding winning stickers in packages with prizes, including a trip to Rio de Janeiro, backpacks, cinema passes for a year, and 3D glasses.

The promotion ended May 30, 2011, and was available in Ecuador, Peru, and Colombia. In June 2012, Oreo posted an ad displaying an Oreo cookie with rainbow colored cream to commemorate Gay Pride Month. The cookie itself is not being manufactured or available for sale. The ad prompted some negative comments but Kraft stood by their promotion stating "Kraft Foods has a proud history of celebrating diversity and inclusiveness.

We feel the Oreo ad is a fun reflection of our values." The Gay Pride ad was followed during 2012 by a series of ads commemorating other holidays and events, including a red, white and blue cream Oreo for Bastille Day, a stream of cookie crumbs for the appearance of the Delta Aquarid meteor shower, and a cookie with a jagged bite taken out of it for Shark Week.
