Preheat oven to 350°F. Scoop cookie dough into the bottom of a lined mini muffin tin and bake until just golden, about 7 minutes. Add mini marshmallows to the top of each cookie. Bake or broil again until the marshmallows are puffed up and golden. When the marshmallows have puffed up and turned golden, add a Hershey kiss or chocolate chunk to the center of each cookie cup.
