      If you want a special treat for a birthday boy or girl who prefers cookies to cake, look no further. This super festive sprinkle filled birthday cookie cake screams party and is sure to delight your favorite cookie lover.

      I cannot believe it took me so long to share this scrumptious party ready dessert with you. I actually made it for my sister-in-law’s birthday back in November.

     But December was chock full of Christmas posts and giveaways, so I am finally able to share it with you. It is definitely worth the wait!

     When asked what her birthday treat request was she said sprinkles. 😃 I told her I could put sprinkles on just about anything so that would be easy enough.

    When pressed she gave me vanilla and cookies to go on. So I figured a cookie cake filled with sprinkles would be just the thing.

       The best part is how quick it was to make. The beauty of doing a cookie as bars or a cookie cake is you don’t have to put trayful after trayful of cookies in the oven. There is just one trip to the oven and a delicious giant cookie emerges.

     You just smoosh the dough into a pan and throw it in the oven! Plus that helps ensure a super chewy center. 😍 Just a little bit of crispy around the edge and perfect soft cookie goodness in the middle.

     I used my 12″ tart pan because I was feeding a crowd and I think the scalloped edges are fun. But don’t worry if you don’t have one.

     A 12″ oven safe skillet would work. Just make sure it’s deep enough. Otherwise you could bake it in two 9″ cake or pie pans. Even a 10×15″ pan or lasagna pan would work.

     Of course I couldn’t have a birthday treat without frosting, so I piped on a quick border of sweetened condensed milk buttercream. Then another dusting of sprinkles really pulled it all together.

      It is actually fitting that I had to wait until now to share this though as the blog is celebrating its 4th birthday! A lot has changed in those 4 years and it has been a fun ride.

     What started on a whim has become a creative outlet. It has also enabled me to meet and become friends with people from all over the world.

      It will be fun to see where this year takes us. As always, I am open to suggestions. But no matter what, I am sure there will be more frosting and sprinkles along the way!

Tips and tricks for making a birthday cookie cake

  • Make sure to use jimmies in the cookie. Nonpareils will melt into the dough and make a brown mess.
  • Nonpareils are cute sprinkled on top though!
  • Using a couple of nine inch cake or pie pans will work if you don’t have a 12″ tart pan.
  • A 12″ cast iron skillet will also work great!
  • You can bake the cookie ahead of time and wrap it tightly in plastic wrap. Then freeze it until part day, then defrost and decorate. 
  • If you prefer chocolate chips, they would be fun too. White chips just better matched my sister-in-law’s vanilla request. 
  • This could easily be made into cookie bars and baked in a 9×13″ pan.

You could definitely customize it according to the occasion. My sisinlaw is a yellow lover, so it was fun to frilly it up for her.
