The cookie dough variety is a chocolate-flavored cookie with a dough-flavored filling. Marshmallow Crispy is likely inspired by the Rice Krispies treat, with crisped rice dotting the vanilla-flavored cream filling. Last year, Nabisco created two other Oreo flavors, watermelon and Candy Corn.

Indie rockers Tegan & Sara will appear in a commercial that will show a one-time-only hashtag for "fans with the fastest thumbs" to tweet for some new cookies, according to USA Today.

Twitter was pretty excited about the additions.

I have never clicked on a news story faster than "Oreo adds two new flavors."
