As you can see via the packaging (shown above), the Peeps Oreos are made with two golden cookies with a bright pink marshmallow Peeps-flavored creme in the middle. The filling appears to have a gritty, sugary texture similar to a typical Peep, although it's bound to look different in real life. So far, it's unclear if the filling also features Peeps' strange, slightly bitter food coloring-like flavor, too, but either way, the cookies will likely be just as polarizing as the chick-shaped marshmallows.
Anyway, if Peeps-flavored Oreos sound like your jam, then cheers to many glasses of pink milk. Or, if you really want to go crazy, dip 'em in some of this Peeps-flavored milk.
