In the bowl of a stand mixer beat the butter, sugar, brown sugar and vanilla until creamy. Add the egg, beating well until thoroughly combined.
In another large bowl, sift together the flour, salt and baking soda.
Slowly add the flour mixture until it has all been incorporated. Stir in the chocolate chips and candy cane pieces with a wooden spoon until evenly distributed.
Spray the skillets with vegetable oil cooking spray then divide the dough between the skillets and spread the dough evenly. Bake until the edges are golden and the middle is still gooey, about 20 minutes.
Remove from the oven and let sit for 5 minutes before topping with scoops of ice cream. Serve warm and eat it out of the skillet.
