Cookies 'n Cream Brownies
Homemade Oreo Blizzards
Chips AhOreos (and 'Nilla Wafer Oreos)
The Chips AhOreo is something I'd actually eat. 'Nillas are really, um, sweet, and I don't have much else to say about them. I guess there's a reason chocolate and creme filling go together.
Peanut Butter and Nutella Oreos
And it's pretty awesome: the experience of a milk-laden Oreo without any chewing to get in the way. Change the ratios of cookie to creme depending on how sweet you want it; but the inclusion of those little white bits does help it to taste like an Oreo.
