Tips for Making the Best Chocolate Chip Cookie Cake

– Taste the chocolate frosting before decorating the cake. If it's too sweet, add a pinch of salt.

– While any milk works in the frosting, whole milk is best for that ultra-rich creamy texture.

– You can make this recipe ahead of time. The cookie dough will last 3 days in the fridge or up to 3 months in the freezer.

How to Store Cookie Cake

Instructions

Place the flours, baking soda, and nutmeg in a large bowl. Whisk to combine.

Put the butter, both sugars, and salt into the bowl of your stand mixer. Beat until smooth, about 3 minutes on Medium. Crack in the egg and beat for 1 minute. Scrape down the bowl, then add the egg yolk, beat for 1 minute, and scrape the bowl down again. Pour in the milk and vanilla, beat to combine.

Set the mixer's speed to low, then gradually add the flour mixture until the dough starts to come together. Add the chocolate chips.

Refrigerate the dough for a minimum of 1 hour. Then preheat your oven to 350°F.

Spray a springform pan with cooking spray. Press the cookie dough into the pan, forming a single even layer. Bake for 20 to 25 minutes. Remove from oven to cool.

To make the chocolate buttercream frosting, mix the powdered sugar and cocoa powder in a large bowl. In a second bowl, cream the butter with an electric hand mixer until whipped and airy, about 2 minutes. Add half the dry ingredients and beat. Beat in the milk and vanilla, then pour in the remaining sugar mixture, and mix until completely combined for about 2 to 3 minutes.

Once the cookie cake is completely cool, remove it from the springform pan and decorate with frosting.
