How Long to Cook Skillet Chocolate Chip Cookie (10-inch, pizookie-style) in the cast iron
Specification: Full batch of standard drop cookie dough (about 3.5 cups) pressed evenly into a greased 10-inch cast-iron skillet, baked as one giant cookie without preheating the pan
3-Step Execution Protocol
Heat cast iron skillet over 350°F (177°C) — the classic cookie temperature until lightly smoking. Prepare skillet chocolate chip cookie (10-inch, pizookie-style) (Full batch of standard drop cookie dough (about 3.5 cups) pressed evenly into a greased 10-inch cast-iron skillet, baked as one giant cookie without preheating the pan).
Cook for 22–28 mins (for gooey center) — pull earlier for softer, later for crispier. Do not flip; allow surface to develop undisturbed.
The edges are deep golden-brown and pulling slightly from the skillet, but the centre 3 inches still look slightly underbaked and puffed — the residual heat in the cast iron finishes the centre over the 10-minute rest. Fully-baked-in-oven centre = dry cookie by the time it hits the plate. Confirm internal temperature reaches 195°F–200°F at the centre — soft-set with residual bake finish. Rest for 10 minutes before serving.
