Thanks to Oreo, cookie-lovers will be flocking to the candy isles today.

In a partnership with Milka, Oreo just dropped its first-ever chocolate bars: The Oreo Chocolate Candy Bar and The Oreo Big Crunch Bar. The former is filled with vanilla creme and bits of Oreo cookies, then coated in Milka chocolate. As the Los Angeles Times notes, it’s sort of like a crushed double-stuffed Oreo that’s been covered in chocolate.

The latter is the bigger of the two, at a whopping 10.5 ounces. This chocolate bar is an Oreo cookie that’s been sandwiched between two layers of vanilla creme filling, then coated in Milka chocolate. As Eater describes, it resembles an inside-out Oreo cookie.

 

For those scurrying to the nearest grocery store to find the candy bars, there’s a catch: Although there’s a limited rollout of The Oreo Big Crunch Bar today, a nationwide distribution of both flavors won’t start until Jan. 2017. But once fully distributed, the new bars will be a permanent part of the Oreo family, according to Mondelez mdlz , Oreo’s parent company.

 

For now, those who are looking to taste The Oreo Big Crunch Bar can find it at Walmart, Kroger, ShopRite, and Albertsons, according to Mondelez.

Oreo’s new Chocolate Candy Bar ranges from .98 to $1.79, depending on its size. The Big Crunch Bar is a bit pricier at $4.99, due to its larger size.
