My favorite way to eat a chocolate chip cookie – when it’s the size of a cake! Decorate with frosting, slice, and serve.
- 3/4 cup (170g) unsalted butter, softened to room temperature
- 1 cup (200g) packed light or dark brown sugar
- 1 large egg + 1 egg yolk*
- 2 teaspoons pure vanilla extract
- 2 cups (250g) all-purpose flour (spoon & leveled)
- 2 teaspoons cornstarch (aka cornflour)*
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 and 1/2 cup (225g) semi-sweet chocolate chips
- optional: chocolate buttercream for topping
- Preheat oven to 350°F (177°C). Spray a 9-inch pie dish or cake pan with nonstick spray. Set aside.
- In a large bowl using a hand-held mixer or stand mixer fittedwith paddle attachment, beat the butter for 1 minute on medium speed until completely smooth and creamy. Add the brown sugar and beat on medium speed until creamy, about 1 minute. Mix in egg, egg yolk, and vanilla on medium-high speed until combined. Scrape down the sides and bottom of the bowl as needed.
- In a separate bowl, combine flour, cornstarch, baking soda and salt. On low speed, slowly mix into the wet ingredients until combined. The cookie dough will be quite thick. Add 1 and 1/4 cups chocolate chips and mix for about 5 seconds until evenly disbursed.
- Press the cookie dough evenly into the prepared pan. Bake for 20-25 minutes or until the cake is lightly golden brown (could be up to 30 minutes, depending on your oven). Use a toothpick to test for doneness. You may want to cover the cake loosely with aluminum foil after 15 minutes to avoid heavy browning around the edges. Remove from the oven and set the pan on a wire rack to cool completely. Once cooled, use a sharp knife or metal spatula to loosen the sides of the cookie cake from the pan and transfer to a serving dish. (Or use can serve directly from the pan.)
- The chocolate buttercream is optional. Instead, decorate with whipped cream or top with vanilla ice cream.
- Decorate the cooled cookie cake with frosting and remaining 1/4 cup chocolate chips. Depending how much frosting you use, you may have some leftover. I used a Wilton 1M tip. Cookie cake remains fresh covered tightly at room temperature for up to 3 days.
- Eggs: Make sure you don’t use 2 full eggs, which will result in a cakey texture– think more of a cake than a cookie. 1 whole egg + 1 egg yolk is best. Room temperature eggs incorporate evenly into your cookie dough, which guarantees a uniform texture in each bite of the cookie cake. Simply set out the eggs when you set out the butter to come to room temperature. If you forget to set out your eggs, no worries. Place them into a bowl of warm water for 5 minutes, then use.
- Cornstarch: The cornstarch helps thicken the cookie dough and promises a softer cookie cake. If you don’t have cornstarch, you can leave it out. No need to replace with anything.
