This Chocolate Chunk Pizookie is out-of-this-world delicious and the perfect indulgent dessert to make when you don't have a ton of time or don't want to dirty a bunch of dishes! One pan, half-baked cookies for the win!
Melt butter in a 10 inch cast iron skillet set over medium-low heat. Stir in sugars and vanilla and remove from heat. Let rest until pan is just warm to the touch, but no longer hot. About 5 minutes.
Crack an egg onto the butter and sugar mixture, and use a fork to whisk it into the mixture.
Place flour, baking soda, and salt on top and carefully stir into the mixture until smooth and well-mixed.
Stir in chocolate chunks and chips. Place in the oven for 15-25 minutes or until golden around the edges and still soft in the middle.
