• Place the 3 sticks of salted butter in a microwave-safe container.
• Heat the butter on HIGH for 1 minute. Let it sit in the microwave for an additional minute and stir it with a heat-resistant spatula to see if it has melted. If it hasn't, heat it on HIGH for another 20 seconds, let it sit for 20 seconds, and stir it again. Repeat in 20-second intervals until your butter is melted.
• Pour the melted butter in the bottom of a mixing bowl.
• Add the cocoa powder and mix it in.
• Mix in the 2 cups of brown sugar. Make sure the brown sugar is completely incorporated.
• Add the baking soda and salt to your mixing bowl. Mix until they are completely combined.
• Add the vanilla extract and the mint extract. Mix them in thoroughly.
• Feel the sides of the mixing bowl. If the contents are so hot that it might cook the eggs if you add them now, let everything cool to slightly above room temperature.
• Add the beaten eggs to your mixing bowl. Mix them in thoroughly.
• Add the flour to your mixing bowl in half-cup increments, mixing after each addition.
• Once the flour has been thoroughly incorporated, scrape down the sides of the bowl with a butter spatula and take the bowl out of the mixer.
• Set the bowl on your counter and give it another stir.
• Add the cup of mini chocolate chips and stir them in by hand. Make sure they're evenly distributed.
• Cover your bowl with plastic wrap and place it in the refrigerator for 2 hours. (Overnight is fine, too.)
• Once your cookie dough has chilled and you're ready to bake, take the bowl out of the refrigerator.

Preheat the oven to 350 degrees F., rack in the middle position.

• While your oven is preheating, prepare your cookie sheets by either spraying them with Pam or another cooking spray or lining them with parchment paper [or a silicone baking mat].
• Roll the Chocolate Mint Cookie dough into walnut-sized balls with your impeccably clean hands.
• Working one dough ball at a time, roll the dough balls in the bowl of white sugar and place the balls on your prepared cookie sheets, 12 to a standard sheet.
• Flatten the dough balls a bit with a metal spatula (or with the heel of your hand if the health board's not around).
• Press one Peppermint Pattie in the center of each cookie.

  [See my warning and pictures above, you may want to put the York Peppermint Patties on AFTER baking the cookies, but still press down the dough balls before baking].
• Bake your cookies at 350 degrees F. for 10 minutes.
• Take your cookie sheets out of the oven and cool the cookies on their cookie sheets for 1 to 2 minutes.
• When the cookies have cooled for a bit, use a metal spatula to transfer the cookies to metal cooling racks on your counter. If you leave them on the cookie sheets for too long, they may stick and fall apart when you try to transfer them.
