Preheat the oven to 350 degrees Fahrenheit.
In the bowl of an electric mixer, cream together butter, sugars, vanilla and eggs until well-combined.
In a separate bowl, whisk together flour, salt and baking soda. Add to wet mixture, along with the chocolate chips, and mix just until combined.
Spread/press the dough into a nonstick, OVEN-SAFE skillet (approximately 11 1/2" in diameter).
Sprinkle and press additional semi-sweet chocolate chips and Trees and Stockings White Creme Chips on top.
Bake for approximately 14-17 minutes, or just until set and not too brown. If you want it to be more of a pazookie (on the gooey side, you'll want to underbake it by a few minutes).
Let cool slightly, then slice and serve (with ice cream or by itself).
