If you’re looking for an easy and fun cake for a birthday or celebration, look no further than this chocolate chip cookie cake. The only thing better than a batch of homemade chocolate chip cookies is a giant chocolate chip cookie decorated with decadent chocolate frosting and colorful sprinkles. It’s an effortless treat that arguably pairs even better with a scoop of ice cream than a homemade vanilla or chocolate cake.

This recipe is not only easier than making a layer cake, but it’s even easier than making standard chocolate chip cookies. There’s no need to chill the dough, no scooping cookies, and no cake assembly. With a traditional cake, you might spend more time assembling and decorating than actual partying. Although you should plan on at least 2 hours to prepare this cake from start to finish, there are some make-ahead options below for the busy party planners.

First, Make a Giant Cookie

Making the chocolate chip cookie base is just like making chocolate chip cookies, but with fewer steps. First, beat the butter, brown sugar, vanilla extract, and salt together until light and fluffy. Mix in the egg, followed by the flour and baking soda. Finally, add a (generous) cup of chocolate chips and mix them in by hand with a rubber spatula. 

Many chocolate chip cookie recipes tell you to chill the dough, but here you can transfer the dough into a greased 9-inch cake pan and bake right away. 

Then, Make the Frosting

Chocolate frosting and sprinkles are what turn this giant chocolate chip cookie into a cake fit for a celebration. To make the chocolate buttercream frosting, start by melting the chocolate. Place 1/2 cup of chocolate chips (about 3 ounces) in a microwave-safe bowl and microwave in 30-second bursts until melted and smooth, stirring with a rubber spatula or spoon after each burst. 

Set the chocolate aside to cool slightly so it doesn't melt the butter in the frosting. Beat the softened butter for 2 minutes until pale and creamy. Add the sifted powdered sugar and the vanilla extract and continue mixing until smooth. Pour in the cooled, melted chocolate and beat until uniform in color. Pause and scrape the bottom and sides of the bowl with a rubber spatula as needed. The frosting should be silky and rich coffee brown.

How To Pipe Buttercream

Piping buttercream frosting may seem overwhelming for those not experienced with cake decorating, but by practicing just a couple of techniques you can create a expertly decorated cakes as well.

  • Be sure to wait until the chocolate chip cookie cake has cooled completely before frosting, otherwise, the frosting will melt. 
  • Fit the piping bag with a star tip (like the Wilton 1M or 21 tips). Fold the top of the bag over one hand while using the other to scoop in the frosting with a spatula, filling the bag about half full. 
  • When piping stars or rosettes, hold the bag straight up and down. To make a star, hold the tip about 1/4-inch above the cookie cake and squeeze the bag to form a star. More pressure will make a larger star. 
  • To make a rosette, begin like making a star, but move the tip in a tight circle using even pressure. When the circle is complete, stop pressure, then lift the tip away.
  • To get the hang of it before decorating the cake, you can practice on a scrap piece of parchment paper, then scrape the frosting back up and refill the piping bag.

Make Ahead of Time

I think this cake is best when it’s baked the same day it’s served, but that doesn’t mean you can’t work ahead. It’s easy to make the dough or the frosting (or both!) ahead of time.

The cookie dough will keep in an airtight container in the refrigerator for up to 3 days. When you’re ready to bake, bake as directed straight from the fridge.

The frosting will keep in the refrigerator for up to 1 week in an airtight container. At least 1 hour before using, take the frosting out of the refrigerator to allow it to come up to room temperature. Then give it a quick whip until smooth and fluffy.
