A Note From the Baker
This isn’t just a big cookie—it’s a celebration centerpiece. Combining the chewy, buttery comfort of a classic chocolate chip cookie with the shareable joy of a cake, this recipe is perfect for birthdays, game days, or any day that calls for a giant dose of happiness. With crisp edges, a soft, gooey center, and pockets of melted chocolate in every slice, it’s designed to be baked in a springform pan for easy serving and maximum visual impact.
Ingredients
For the Cookie Cake:
-
2 ¼ cups (281g) all-purpose flour
-
1 tsp baking soda
-
1 tsp fine sea salt
-
1 cup (2 sticks / 227g) unsalted butter, softened to room temperature
-
¾ cup (150g) granulated sugar
-
¾ cup (165g) packed light brown sugar
-
2 large eggs, at room temperature
-
2 tsp pure vanilla extract
-
2 cups (340g) semi-sweet chocolate chips or chunks
-
½ cup (65g) chopped toasted walnuts or pecans (optional)
For Decoration (Optional):
-
Vanilla ice cream, for serving
-
Whipped cream
-
Additional chocolate chips
-
Sprinkles
Equipment
-
9-inch springform pan
-
Parchment paper
-
Electric hand mixer or stand mixer
-
Medium mixing bowl
-
Rubber spatula
-
Cooling rack
Instructions
Step 1: Prep & Preheat (Time: 15 minutes | Intensity: Low)
-
Preheat your oven to 350°F (175°C).
-
Grease the bottom and sides of your 9-inch springform pan. Line the bottom with a circle of parchment paper for foolproof removal.
-
In the medium bowl, whisk together the flour, baking soda, and salt. Set aside.
Step 2: Cream the Butter & Sugars (Time: 5 minutes | Intensity: Medium)
-
In the bowl of your mixer, beat the softened butter, granulated sugar, and brown sugar on medium-high speed for 2-3 minutes, until the mixture is very light, fluffy, and pale in color. Scrape down the sides as needed.
Step 3: Incorporate Eggs & Vanilla (Time: 3 minutes | Intensity: Low)
-
Add the eggs one at a time, beating well on medium speed after each addition until fully incorporated.
-
Beat in the vanilla extract. Your mixture should now be smooth and slightly glossy.
Step 4: Combine Dry & Wet (Time: 4 minutes | Intensity: Low-Medium)
-
With the mixer on low speed, gradually add the flour mixture. Mix just until the flour disappears. Do not overmix.
-
Using the rubber spatula, fold in the chocolate chips and nuts (if using) by hand until evenly distributed. The dough will be thick and luxurious.
Step 5: Bake to Perfection (Time: 30-35 minutes | Intensity: Passive)
-
Transfer all the dough to the prepared springform pan. Press it evenly across the bottom and smooth the top with your spatula or damp hands.
-
Place the pan on the center rack of the preheated oven. Bake for 30-35 minutes. The cake is done when the top is golden brown, the edges are set and pulling slightly from the pan, and the center looks just set (a light press should leave a slight indentation—it will firm up as it cools).
-
Pro-Tip: For an extra-gooey center, err on the side of 30-32 minutes.
Step 6: The Crucial Cool (Time: 45 minutes | Intensity: Passive but Critical)
-
Place the hot pan on a cooling rack. Let the cookie cake cool completely in the pan for at least 45 minutes to 1 hour. This patience is key for clean slicing.
-
Once cool, run a knife around the inner edge, release the springform clasp, and carefully remove the ring. Transfer the cake (with parchment paper bottom) to a serving plate.
