Mix one box of brownie mix (18.2 ounces) with one egg, water, and vegetable oil in a large bowl. Stir or whisk until ingredients are fully blended. If you want, you can add chocolate chips or chopped nuts to the batter, as well.

Grease (or spray) 4- six inch cast iron skillets. Evenly divide the brownie batter between the skillets, and level it out with a spatula or the back of a spoon.

Preheat oven to 350° F. Once at temperature, place skillets on the middle rack. Bake for 17-22 minutes. Ovens can have temperature fluctuations, so your baking time may be a little different. Check them at the 17 minute mark by inserting a toothpick into the middle of one. If it comes out fairly clean, it is done. When done, remove from oven and let them cool for 3-5 minutes.

TIP: If you like brownies slightly underdone and gooey : oven-baked are "usually" ready at about 17 minutes. If you like brownies more done: they're "usually" ready at about 20- 22 minutes.

Make sure hopper is full of pellets. Turn to SMOKE setting (lid open) and let fire get established (about 4-5 minutes). Once smoking and established, turn temperature setting to 350° F. Close lid and preheat for 10-15 minutes to reach temperature. Place skillet brownies directly onto grill grate once temp. has been reached. Bake (lid closed) for 20-25 minutes until your desired done-ness, or until a toothpick inserted into middle of brownie comes out fairly clean. Cover skillet with foil, if the edges begin to brown too quickly. When done, remove skillets from grill, and let them cool for 3-5 minutes.

While brownies are still warm, top each skillet with a scoop of ice cream. Drizzle with chocolate or caramel sauce (or both!), and garnish with a maraschino cherry, or other toppings (as desired)! Each of the skillet brownies is 2 servings, so give everyone a spoon or fork, and let them dig in! Enjoy!
