NEWARK, N.J. — Mars Inc.’s Snickers brand is launching Snickers Peanut Brownie nationwide starting in December and it is also available now for pre-order on Walmart.com.

Snickers Peanut Brownie features individual squares of a layer of caramel and a chewy peanut-brownie filling, coated in the classic Snickers chocolate.

Snickers first offered fans the chance to get an exclusive taste of the new product in July. More than 40,000 fans signed up to “get in line” and be notified when the offer would be available, and when the clock ticked down to zero, all 1,000 boxes from the brand’s first batch were claimed within three minutes.

“Since our announcement this summer, fans have shown tremendous enthusiasm toward Snickers Peanut Brownie — and now the wait to try our biggest innovation to date is over,” said Josh Olken, brand director of Snickers. “We’re excited for all of our fans to get their hands on this new satisfying mashup of two beloved and comforting treats: Snickers bars and brownies.”

Snickers Peanut Brownie will be available in single (1.2 ounces), share (2.4 ounces) and sharing stand up pouch (6.61 ounces) sizes.
