Preheat the oven to 350 degrees.
Coat a mini cast iron skillet with butter, then add The Cool Cookie cups into the skillet. Press down each cookie dough cup until smooth. (Optional add more goodies to the dough!)
Bake the cookie skillet for about 10-12 minutes, until golden brown.
While the spooky skillet cookie is baking, build out your sweet treat board: halloween candy, M&Ms, cupcakes, & decorative pumpkins!
Remove from the oven and let cool before adding the icing decorations.
Enjoy!
