When there’s a birthday in my house, I often skip the traditional cake and serve a fun and festive dessert such as cake balls, cosmic brownies, or this amazingly delicious cookie cake.

I love a good birthday cake, but I sometimes I like to switch things up a bit and serve a cookie cake instead. It’s always an unexpected and welcome surprise and it’s sure to get rave reviews!

This recipe starts with your typical cookie ingredients including butter, two types of sugar, eggs, flour and vanilla. All of the ingredients get mixed together, then the dough is pressed into a cake pan. A sprinkling of extra chocolate chips goes over the top and the cookie is baked until golden brown. After the cake is cooled, it’s time to add the decorations. I add a layer of chocolate frosting and a generous amount of sprinkles.

A cookie cake will be golden brown when it’s ready to come out of the oven. The edges should be a slightly darker shade of brown and pulling away from the edges of the pan. You can also check the center of the cookie by inserting a toothpick. If the toothpick comes out clean or with just a few crumbs attached, you’ll know that it’s finished baking.

The cookie dough for this recipe can be made up to 3 days before you plan to bake your cake. You can use any type of chocolate chips in this recipe. While I typically use semi sweet chocolate because it’s traditional, other great choices are milk chocolate, white chocolate or a combination of chips. I like the addition of chocolate frosting, but if you’d prefer to use a vanilla frosting, simply omit the cocoa powder in the frosting recipe and double the amount of vanilla extract. I use a piping bag fitted with an open star tip to decorate my cookie with the frosting. If you don’t have a piping bag, you can put your frosting into a resealable gallon sized bag and snip the tip off to pipe dollops of frosting.

If you’re going to eat the cake on the same day that you make it, I recommend storing your cake uncovered at room temperature. If you’re making your cake ahead of time, you can cover it loosely with plastic wrap and store it in the fridge for up to 3 days before you serve it. You should plan to let your cookie cake sit at room temperature for 20-30 minutes before serving if it’s been in the fridge.
