In a medium bowl, mix together butter and sugars until combined. Add in vanilla and egg. Slowly stir in the flour, baking soda and salt, then fold in chocolate chips.
Press the cookie dough mixture into the bottom of an 8inch cast iron skillet.
Bake for 8-10 minutes (it will be gooey and under done).
Pull out of the oven and top with ice cream, then drizzle with chocolate sauce.
Serve while still warm (and before the ice cream melts!).
Notes
Change up your chocolate chips and chocolate chip ice cream for your other favorite cookie additions and ice cream flavors! We like it with toffee chips and pralines and cream, or M&Ms and chocolate peanut butter ice cream!
Use high-quality chocolate for the melty chocolaty center.
You can do what you'd like with this recipe. Feel free to switch out the chocolate chips or top the delicious dessert with your favorites: white chocolate chips, M&Ms, peanut butter chips, butterscotch chips, macadamia nuts, hot fudge, any time of ice cream, whipped cream, caramel sauce, peanut butter sauce, and chopped nuts.
