Besides pudding and ice cream.
Me and my friend made Oreo cookies once, you just get normal cookie mix and cover the Oreo in it, then cook it for the normal time, and you get amazing cookies with hot oreo inside :D
2 different things. 1. Get whip cream. Crush the oreos a bit but leave some big chunks. Mix together &Voila! You have a dessert, 2. Get milk Dip.
Aha! Nvm about the first one, here are better instructions! http://funadvice.com/r/15q051breh1
Put them in milk-shake, or if you have enough grind them into a crust and make a pie.
