Twist the oreos to separate them (see notes), and scrape off the cream filling (either discard the filling...or eat it, if you're into that.)

Melt (and temper, if you can be bothered - see notes) the chocolate, then stir in the mint extract well.

Dip an oreo half in the melted chocolate, turn to coat using a fork.

Use the fork to remove the oreo from the chocolate, tap it on the edge of the bowl a few times (to let excess chocolate drip off) and transfer to a lined cookie sheet.

Leave at room temperature until set.
