Found this recipe on Pinterest. You can find it Here. I used chocolate bark. You can find it on the baking isle.
16 to 20 oreo cookies
7 to 10 oz semisweet or bittersweet chocolate
1 tsp mint extract
Twist the oreos to separate them and scrape off the cream filling.
Melt 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.
