To a large bowl, add the cake mix, egg, cream cheese, butter, vanilla extract, and peppermint extract. Mix together until ingredients are well combined.
Stir in the Oreo chunks, chopped Andes mints, chocolate chips, and M&Ms. Refrigerate for 30 minutes-2 hours (depending on how much time you have) Refrigerating the dough controls the spread of the cookie on the baking sheet and keeps them soft, fluffy, and thick.
After chilling preheat oven to 350 degrees F. Line a cookie tray with parchment paper and using a cookie scoop scoop the dough out onto the cookie sheet, leaving 2 to 3 inches of room between each cookie.
Bake for 11 minutes and let sit on the cookie tray for 2 minutes before placing on a cooking rack. Wait for the cookies to completely cool down before serving. Enjoy!
