1-First Step: Prep Your Workspace Preheat your oven to 350°F (175°C). Grease a 12-inch pizza pan or round cake pan lightly with butter or non-stick spray. Line the bottom with parchment paper for easy removal. This prevents sticking and ensures even baking. Measure all ingredients ahead for smooth mixing, a trick busy parents swear by.

2-Second Step: Cream the Sugars and Butter In a large bowl, beat ¾ cup softened butter, ¾ cup brown sugar, and ¼ cup white sugar. Use a hand mixer on medium speed for 2-3 minutes until light and fluffy. Scraping the bowl sides keeps it even. This step aerates the dough, creating that signature chewy texture in your chocolate chip cookie cake.

3-Third Step: Add Wet Ingredients Crack in 1 egg, then add 1 tsp vanilla extract and 1 tsp baking soda. Mix on low until combined, about 1 minute. Avoid overmixing to prevent toughness. The baking soda reacts with sugars for lift, while vanilla boosts flavor depth.

4-Fourth Step: Incorporate Dry Ingredients and Chips Sift in 2 cups all-purpose flour gradually, mixing on low. Fold in 1 ½ cups chocolate chips by hand for even distribution. The dough will be thick and sticky, perfect for spreading. Reserve a handful of chips for topping if desired.

5-Fifth Step: Shape and Bake Transfer dough to the prepared pan. Use wet hands or a spatula to spread evenly, about ½-inch thick in the center. Sprinkle extra chips on top. Bake 20-25 minutes. Edges turn golden, center stays soft, check at 18 minutes to avoid overbaking. Rotate pan halfway for uniform browning.

6-Final Step: Cool and Serve Remove from oven and cool in pan 10 minutes, then transfer to a wire rack. Full cooling takes 1 hour for clean slices. Frost if wanted, or serve warm with milk. Store as noted below. Pro tip: Press center lightly; it should spring back slightly when done.
