A thick and chewy chocolate chip cookie cake can be decorated for any special occasion including a birthday party. It's easy to add "happy birthday" or any special message to the top of the giant cookie using frosting.
If you are celebrating a birthday and the guest of honor prefers cookies over a cake, this recipe is for you.
Everyone in my family falls into this category and they all love it when I show up to a birthday party with one of these giant chocolate chip cookie cakes.
Seriously, what's not to love? The cookie is crispy around the edges and soft and chewy in the middle. It's packed with a combination of dark and milk chocolate chips and decorated with vanilla and chocolate marshmallow frosting. YUM!
You can go out and buy one of these cookie cakes but homemade is so much better especially if you use this easy chocolate chip cookie cake recipe.
Let's make some cookie dough!
butter - Use unsalted butter. There's no need to set it out ahead of time as you will be melting the butter.
brown sugar - You can use light or dark brown sugar. I like using dark brown sugar to give my cookies a richer flavor but either will work fine.
eggs - You'll use 1 whole egg and 1 egg yolk. The extra egg yolk not only adds richness to the cookie dough but it also makes your cookie dough creamier resulting in softer cookies.
vanilla - Use pure vanilla extract or vanilla bean paste to flavor your cookie dough.
flour - It's important that you use all-purpose flour to make these cookies and it's best to weigh the flour for the most accurate measurement. If you don't have a kitchen scale, be sure to spoon the flour into your measuring cup, then run a knife over the top edge of the cup to remove any excess flour.
cornstarch - Adding cornstarch to your chocolate chip cookie dough will help to keep your cookies soft and chewy in the middle.
salt - A little salt is important to balance out the sweetness in your cookie recipes.
baking soda - Your cookies need a little lift and baking soda will do the trick.
chocolate chips - I like a blend of dark and milk chocolate chips in my cookies. You can use any combination of chocolate chips that you like. Just be sure to reserve some to sprinkle over the top of your cookie cake. You are serving it for a special occasion and you want it to look really nice!
frosting - I've shared an easy recipe for marshmallow frosting but you can use your favorite buttercream or store-bought frosting if you prefer.
Mixing the cookie dough.
This chocolate chip cookie dough is easy enough to make in a bowl. There's no mixer needed.
You'll mix melted butter with brown sugar and granulated sugar before mixing in an egg, then an egg yolk. and then a splash of vanilla. Combine the wet ingredients with the flour, baking soda, salt, and cornstarch, then stir in all but ½ cup of the chocolate chips. Easy, right?
Grab a 14-inch round deep dish pizza pan or a 14-inch cake pan and grease it with butter and flour or spray it with baking spray with flour. For easy removal, be sure to line the bottom of the pan with parchment paper. I like to use a circle of parchment paper but strips crisscrossed in the bottom and up the sides will work too.
Pat the dough into an even layer in the pan then sprinkle on the remaining chocolate chips.
How to decorate your chocolate chip cookie cake?
To make this birthday cookie cake, I filled two pastry bags, each fitted with a large open star tip (I used Wilton 4-B tips, with vanilla frosting and chocolate frosting and piped a border of alternating, chocolate and vanilla, stars around the edge of the cookie.
I frosted this cookie cake using homemade marshmallow frosting (see the easy recipe below) but you can use your favorite homemade buttercream frosting or you can use store-bought frosting. I love using Wilton Decorator Icing because it is stiff enough to hold peaks when piped and it has a nice flavor.
To pipe on the "Happy Birthday" message, I filled a pastry bag fitted with a smaller Wilton #21 star tip with white frosting and piped on the letters. Then, I added a line of chocolate frosting over the top using a #3 Wilton round pastry tip.
To make the balloons, I used red, blue, yellow, and white modeling chocolate. You can find the easy 2-ingredient modeling chocolate recipe over on my Hungry Happenings blog. You can use fondant or even frosting if you prefer.
Roll a small amount of red modeling chocolate into a ball, shape it into a teardrop, then flatten it slightly. Repeat, using blue and yellow. Then, pinch off tiny pieces of white modeling chocolate, shape them into oval shapes, and press them onto the balloons to create highlights.
Attach the balloons using a dab of frosting then pipe some strings from the bottom edge of the balloons.
