Hey y’all! This Wednesday I bring to you a funfetti confetti cookie cake! Oh my goodness. This dessert makes any celebration 1000 times better. Birthdays are not complete without it, heck, no celebration is complete without it. I decided to make this cookie cake to celebrate the Lilly Pulitzer After Party Sale!
For anyone who doesn’t know me, I am obsessed with Lilly Pulitzer. They have the cutest printed dresses and clothing that are filled with bright colors. This is a major event since there are only two sales a year. What better way to celebrate than with a soft, chewy, colorful funfetti cookie cake? This cake is loaded with rainbow sprinkles, white chocolate chips, and a buttercream icing that is to die for.

Don’t mind the crack! #bakingproblems
I made this cookie cake using a springform pan (like you use for cheesecakes). This cookie cake rises a lot so a springform pan is needed so the cookie dough doesn’t rise over your usual shallow cake pans. I always spray my pans with Pam Baking Spray (the blue can). It works better than anything else, trust me.
This cookie cake is made with your typical cookie ingredients. An extra egg yolk makes the cookie cake more moist. Corn starch makes it have that extra chewiness/thickness factor. I would not recommend making this cookie cake without it!

Hi! I’m Michelle and I just started a blog recently as well… I found your blog via Sally’s post and just wanted to say that this is adorable! That shot of the cookie dough looks incredible… I wouldn’t blame you if you “sampled” some before baking this cake. 😉
Hi Michelle! Thanks for stopping by! And I may or may not have licked dough right off the spoon!
