Instructions
To Make Chocolate Chip Cookie Cake:
Preheat the oven to 325°F (165°C).
In a large mixing bowl, stir together the melted butter and sugar until well combined.
Add the vanilla extract and eggs, mixing until fully incorporated.
Add the flour, salt, and cornstarch, and mix until just combined.
Stir in the corn syrup until evenly distributed throughout the dough.
Fold in the chocolate chips.
Generously spray a rimmed baking sheet with baking spray. I use an 11x17-inch pan, but a 10x15-inch pan will also work, the cookie cake will just be slightly thicker and may require a few extra minutes of baking time.
Transfer the dough to the prepared pan and press it into an even layer. Tip: To make this step easier, lightly spritz a piece of wax paper with baking spray and use it to press the dough evenly into the pan. Bake for 20–25 minutes, or until the edges are golden and the center is set.
To Make Cookie Cake Buttercream Frosting:
In a large mixing bowl, beat the softened butter and shortening together for 3 to 4 minutes until light and creamy.
Gradually mix in the powdered sugar, starting on low speed to avoid any mess.
Add the milk (or heavy cream), along with the vanilla and almond extracts. Beat on medium speed for about 5 minutes, until the frosting is smooth and fluffy.
If desired, add gel food coloring and mix until evenly tinted. Or divide into smaller bowls to add gel coloring for multiple colors.
