Ingredients
Method
- Heat-treat the flour in the microwave until it reaches a safe temperature, then allow it to cool completely before preparing the cookie dough.
- Preheat the oven to 350°F. Line a 9-inch springform pan with parchment paper, leaving the paper slightly above the rim, and lightly grease the pan.
- Combine the graham cracker crumbs, sugar, and salt before stirring in the melted butter until evenly coated.
- Fold the mini chocolate chips into the crumb mixture.
- Firmly press the mixture across the bottom and slightly up the sides of the prepared pan.
- Bake the crust for 8 minutes, then reduce the oven temperature to 325°F while it cools slightly.
- Stir the softened butter and brown sugar together gently by hand until smooth without whipping excess air into the mixture.
- Mix in the milk and vanilla until combined.
- Fold in the cooled flour and salt, then stir in the chocolate chips until a soft dough forms.
- Place a large roasting pan on the lower oven rack and bring about 5 cups of water to a boil for the steam bath.
- Beat the cream cheese, sugar, and cornstarch on low speed until completely smooth.
- Mix in the eggs one at a time, followed by the egg yolk, blending gently after each addition.
- Stir in the vanilla and sour cream until fully incorporated without overmixing.
- Fold the mini chocolate chips into the cheesecake batter using a spatula.
- Scoop eight tablespoon-sized portions of cookie dough onto a parchment-lined plate and refrigerate for decorating later.
- Spread the remaining cookie dough evenly across the baked crust.
- Pour the cheesecake batter over the cookie dough layer and smooth the surface.
- Carefully pour the boiling water into the roasting pan and immediately place the cheesecake on the rack above it.
- Bake for about 1 hour 20 minutes, or until the edges are set and the center still jiggles slightly.
- Turn the oven off, crack the oven door open, and let the cheesecake rest inside for 45 minutes.
- Remove the cheesecake, sprinkle additional mini chocolate chips over the warm surface, and cool at room temperature for 30 minutes before refrigerating uncovered for at least 12 hours.
- Whip the heavy cream, vanilla, powdered sugar, and optional milk powder until stiff peaks form.
- Pipe whipped cream around the edge of the chilled cheesecake, top each swirl with a reserved cookie dough ball, add extra chocolate chips, and serve.

Notes
Every bite combines creamy cheesecake, buttery cookie dough, and plenty of chocolate chips for a bakery-style dessert that's worth the overnight wait. Slice chilled for the cleanest presentation and the richest texture.
