Instructions
For the cookie base:
Place sugars in a medium bowl. Set aside.
Add the butter to a small saucepan set over medium-low heat, swirling occasionally until melted. Alternatively, place the butter in a microwave-safe bowl and microwave in 30-second bursts, stirring between bursts, until melted. Add hot butter to the sugars and stir to combine. Set aside to cool until just warm.
Stir in the eggs, egg yolk, milk, and vanilla until well combined. Using a spatula, gradually mix in the flours, baking soda, baking powder, cornstarch, and salt. Stir in the chocolate chips. Bake now or cover the dough and refrigerate until ready to bake, up to 72 hours.
When ready to bake, preheat the oven to 350°F. Spray a 9-inch spring-form pan with nonstick cooking spray.
Press the cookie dough into the bottom of the prepared pan. Bake for 30 minutes for a gooey center or 35 to 40 minutes to cook completely. Place the pan on a cooling rack and allow the cookie cake to cool completely before removing from the pan and frosting.
For the buttercream:
In the bowl of a stand mixer fitted with the paddle attachment, mix together the sugar and butter. Mix on low speed until well blended and then increase the speed to medium and beat for another 3 minutes. Add the salt, vanilla, and cream and beat on medium for 1 minute, adding more cream if needed.
Spread all over the cooled cookie cake then garnish with sprinkles. Serve or cover and let stand at room temperature for up to 1 day, or refrigerated for up to 3 days. Let come to room temperature before serving.

Notes
*If you don't have dark brown sugar, use light brown sugar. Just note that you will lose some depth of flavor, and the texture will change slightly. More on this in the 'Sprinkle of Science' Tip Box above the recipe.**If you don’t have any bread flour, feel free to use only all-purpose flour, though your cookie cake may not be as chewy. More on this in the Tip Box.Make Ahead: The cookie dough can be stored in greased pan, covered, and refrigerated for up to 3 days before baking. If you need to prep the dough further in advance, check out my article on freezing cookie dough here.
