1-First Step: Preheat and Prep Your Skillet Start your oven at 350°F (175°C). Grease a 10-12 inch cast iron skillet with butter or non-stick spray. This prevents sticking and promotes crisp edges. Gather all ingredients mise en place style. Softening butter takes 30 minutes at room temp; microwave 10 seconds if rushed, but avoid melting fully for best texture.

2-Second Step: Cream Butter and Sugars In a large bowl, beat 1 cup softened butter, 1 cup brown sugar, and ½ cup white sugar until light and fluffy, about 2 minutes with a mixer or spoon. Brown sugar keeps it chewy; white adds crisp. Scrape sides for even mixing. This base builds structure and flavor foundation.

3-Third Step: Add Eggs and Vanilla Crack in 2 eggs one at a time, mixing well after each. Stir in 1 tsp vanilla extract. Batter may look curdled briefly; it smooths out. Eggs bind everything, vanilla brightens taste. Use room-temp eggs for seamless blend.

4-Fourth Step: Mix Dry Ingredients and Combine Whisk 2¼ cups flour, 1 tsp baking soda, and pinch salt in another bowl. Gradually fold into wet mix until just combined; do not overmix. Dough stays thick. Fold in 2 cups chocolate chips last for even distribution. Semi-sweet chips melt best, but mix milk and dark for variety.

5-Fifth Step: Spread Dough in Skillet Press dough evenly into prepared skillet with wet hands or spatula. Aim ½-¾ inch thick; thicker means gooier center. Sprinkle extra chips on top for pretty melt. This shapes your giant cookie pizza.

6-Sixth Step: Bake to Perfection Bake 18-22 minutes. Edges turn golden, center stays soft and jiggly. Rotate halfway for even browning. Toothpick in center shows moist crumbs, not clean. Overbaking dries it; err underdone as it firms cooling. Total bake time varies by skillet size.

7-Final Step: Top and Serve Remove hot skillet. Add 2-3 scoops vanilla ice cream immediately. Let rest 2 minutes; ice cream softens into cookie. Slice wedges, serve with spoons. Pairs with whipped cream or chocolate drizzle. Enjoy warm for peak bliss. Total time: 30 minutes.
