For as long as the makers of Oreo cookies have been launching new products, the innovations have focused on the flavors and / or relative proportions of wafers and creme. (You may recall birthday-cake or cotton-candy Oreos, or Double Stufs, Mega Stufs or Triple Double Oreos.)

Now Mondelez International, which has owned the Nabisco brands since 2011, has made the leap from cookie to candy. In partnership with Milka, a European chocolatier also owned by Mondelez, Oreos are making their way into two candy bars debuting on Monday.

The Milka Oreo Big Crunch Chocolate Candy Bar, an oversized 10.5-ounce meant for sharing (or self-soothing), contains a layer of Oreo wafer between two layers of vanilla creme, all coated with chocolate candy. Suggested retail price is $4.99. The Milka Oreo Chocolate Candy Bar contains a layer of vanilla crème in which are embedded bits of Oreo wafer. It comes in three sizes: 1.44-ounce (98 cents), 2.88-ounce ($1.69) and 3.52-ounce ($1.79).

The rollout begins Monday and should reach all nationwide retailers by January.
