4. Preheat oven to 350 F. Roll the dough to about a 1/4" thickness on a lightly floured surface. Use a cookie cutter or the top of a cup about 2" in diameter to cut circles out of the dough. Place the cut circles onto the prepared cookie sheet and bake for 7-8 minutes or until the cookies are dry to the touch. Remove the cookies to a cooling rack to cool. Repeat with the remaining dough.
5. When cookies are cooled prepare the chocolate coating by placing the chocolate chips, coconut oil and remaining peppermint oil in a large microwave-safe measuring cup. Microwave for 30-second intervals mixing each time and repeating until the chocolate is melted and smooth.
6. Use a fork to dip the cookies into the chocolate to coat completely. Gently tap off the excess chocolate so that a thin even coating remains. Transfer the cookies to a parchment-lined cookie sheet and then place the sheet into the fridge laying flat to allow for the chocolate coating to set and harden, about 20 minutes.
