If you haven't tried them you need to. They're fantastic and unfortunately have become a staple around here.
Here's what you do:
Crush an entire bag of Oreo's in a food processor then add a brick of cream cheese. Whirl that around until everything is mixed and use a small cookie scoop (or your hands) to make balls. Line them on wax paper or a cookie sheet, freeze them for an hour, then dip into melted bakers chocolate or almond bark. Keep them in an air-tight container in the freezer. Try not to eat all of them in one night.
While I was making a batch I thought about making heart shaped ones for Valentine's Day. It worked! Instead of balling them, use a cookie cutter or a knife to make the hearts. Freeze and dip like normal.
After dipping them in chocolate have fun decorating them. I melted white chocolate and the kids helped drizzle it on. We also used food coloring to make pink chocolate to drizzle but those were eaten before I could snap a picture!
Your Valentine's will love them. Mine sure do!
