Place Oreo cookies in the bottom of a blender. Top cookies with milk. (This amount is up to you. Use less milk for a thicker shake, and more milk for a thinner shake.)

Place ice cream on top of cookies in blender. Pour the one Tablespoon of hot fudge on ice cream.

Cover blender with lid and blend until cookies are combined in ice cream and it reaches desired consistency. (I don't blend ours very long so they're nice and thick with chunks of cookie!)

Pour into 2 separate glasses. Top each shake with more crushed Oreos, if desired. Serve immediately and enjoy!
