How to Make It
Preheat & Prep
Warm up your oven to 350°F (175°C). Grease a 9-inch round cake pan or springform so the cookie slides out effortlessly later. The pan will feel just a little warm in your hands—always the first cozy sign something good is coming.
Mix the Dry Ingredients
Whisk together the flour, baking soda, and salt. The mixture will look pale and powdery, like soft baking snow.
Bring the Wet Ingredients Together
In a larger bowl, stir the melted butter with brown and granulated sugars. It will look glossy and caramel-like. Add the eggs and vanilla, and everything comes together into a silky, golden batter.
Combine & Add Chips
Fold your dry ingredients into the wet bowl, stirring until just combined. Then comes the best part—folding in those chocolate chips. The dough gets thick and speckled with glossy chocolate.
Bake the Cookie Cake
Spread the dough into your prepared pan, smoothing the top. Bake for 20–25 minutes until the edges turn a little crispy but the center stays soft. The smell alone is a reward.
Cool & Decorate
Let the cookie cake rest for about 15 minutes on a cooling rack. When you sprinkle a pinch of sea salt over the warm surface, it melts and sparkles just a bit.
Frost with Buttercream
Whip the softened butter into a pale, creamy swirl. Add powdered sugar slowly until fluffy, then beat in the cream, vanilla, and salt. The frosting becomes smooth, airy, and ready to pipe around the cookie’s edges or spread across the top.
Slice & Serve
Cut into 8–10 warm, cozy wedges. Each slice is soft, chocolatey, and perfect for sharing or not sharing.

Ingredients
- 2 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup unsalted butter, melted
- 1 cup packed brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups semi-sweet chocolate chips
- 1 pinch sea salt, for sprinkling on top (optional)
- 1 cup unsalted butter, softened (for frosting)
- 4 cups powdered sugar, sifted
- 1/4 cup heavy cream or whole milk
- 2 teaspoons vanilla extract (for frosting)
- 1/4 teaspoon salt (for frosting)
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9-inch round cake pan or springform pan with butter or non-stick spray, making sure the sides and bottom are well coated.
- In a medium mixing bowl, whisk together the all-purpose flour, baking soda, and salt until well combined. Set aside.
- In a large bowl, stir together the melted butter, brown sugar, and granulated sugar until the mixture is smooth and glossy. Add the eggs and vanilla extract, whisking until fully incorporated.
- Gradually add the dry ingredients to the wet mixture, stirring just until combined and no streaks of flour remain. Fold in the semi-sweet chocolate chips until evenly distributed throughout the dough.
- Press the cookie dough evenly into the prepared pan, smoothing the top with a spatula. Bake for 20 to 25 minutes, or until the edges are golden and the center is set but still soft.
- Remove the cookie cake from the oven and place the pan on a wire rack. Allow it to cool for about 15 minutes. If desired, sprinkle a pinch of sea salt over the warm surface for extra flavor.
- While the cookie cake cools, prepare the buttercream. In a large mixing bowl, beat the softened butter on medium speed for about 2 minutes, until smooth and creamy.
- Gradually add the sifted powdered sugar, about 1 cup at a time, beating on low speed until incorporated. Once all the sugar is added, increase the speed to medium and beat until smooth and fluffy.
- Add the heavy cream (or whole milk), vanilla extract, and salt. Beat on medium-high speed for 2 to 3 minutes, until the frosting is light and spreadable. If it is too thick, add a little more cream; if too thin, add a bit more powdered sugar.
- Once the cookie cake has cooled enough to handle but is still slightly warm, remove it from the pan if desired. Spread or pipe the buttercream frosting over the top or around the edges. Slice into 8 to 10 pieces and serve.
