Crush your Oreos either in a food processor until they are fine crumbs.*
Slowly add in the condensed milk and mix till it forms a cookie dough texture.
Using a small cookie scoop to measure, form your truffles by rolling them in your hands. Lay them on a lined baking sheet. Place a toothpick in each truffle. Refrigerate for an hour so they set.
Once they have set, melt your milk chocolate. Then using the toothpick as a handle, dip the truffles into your melted chocolate. Place them back on the lined baking sheet, remove the toothpick, and refrigerate for 30 minutes, until set.
Melt your white chocolate and then using a ziplock bag, pour the melted chocolate into the bag. Cut the tip of a corner off and use that as a piping bag to create your white drizzle. Allow to set and then serve.
Notes
* You can also crush the Oreos by placing them in a gallon-sized Ziploc bag then crushing them with a rolling pin until they become fine crumbs.
