Oh boy, I’ve been itching to share this cake with you guys for what seems like an eternity. From how it came about to the shimmering sprinkles around the trim, I’m all about this cookie cake! Yes, I said cookie cake! This pretty little party cake is made up entirely of sprinkle cookies and Italian meringue buttercream. Sprinkle cookies turned into cake with buttercream and sprinkles…. I can’t take it!
Okay, so this all started a few weeks a go with a phone call from a client asking me to create a cookie cake for a birthday party. The first thing that flashed in my head were those large cookie cakes you see in malls and that’s really not my thing. However, my client then redeemed herself by saying she wanted a Meghan cookie cake. This immediately peaked my interest, and well, it was time to create a Meghan cookie cake.
I truly had no idea what I was going to come up with, but that day as I was photographing sprinkle cookies, it hit me. Those sprinkle cookies are so ridiculously good and chewy, and if I made them a little bigger they would make an outrageous party cake! This is normally the point where everything else would get put on the back burner so I could test my idea, but I had to wait. I had to make about a kazillion cupcakes for a client in NY so that kind of needed my full attention. You may have noticed on facebook and instagram that I was up to my eyeballs in buttercream 
I’m happy to report the cupcakes were a huge hit at the baby shower, and I got back to Boston just in time to work on the cookie cake. The one thing I want to stress about this cookie cake is that your cookie dough must be cold when it goes in the oven. This way the cookies bake evenly, and you don’t wind up flinging anything when it’s time to assemble 
Another important point is to use a smooth satiny buttercream to frost it. It will make your life much easier. It’s also important to flip the top cookie upside down so you have a smooth surface to frost.
Once I frosted it, I finished it off with some shimmery sprinkles. I have to admit I didn’t want to part with this one, but nothing beats seeing the look on someone’s face when they first see their cake. My client could not believe it was all cookies, and I got word yesterday that it was the talk of the party! As I was working on this cake I got about 25 other ideas, so I’ve got a feeling they’ll be some more cookie cakes in the future. Enjoy!
Ingredients
- 5 (4 ounce) sprinkle cookies
- 1 batch buttercream
- food coloring
- sprinkles
Instructions
- Make Sprinkle Cookie Dough
- Once it has chilled, portion cookie dough into 4 ounces each. I used 5 cookies to build the cake.
- CHILL cookie dough.
- Bake cookies at 325 degrees for 17-19 minutes. You will notice they poof a little in the middle & turn golden around the edges.
- Once they are completely cool stack them up layering with buttercream between each cookie.
- Frost cookie cake & decorate with sprinkles.
Notes
It is very important that the cookie dough is well chilled when it goes in the oven. This will ensure the cookies bake evenly making it easier to build your cake.
You want to serve this cake at room temp.
I recommend using a smooth buttercream such as Italian meringue for this cake. It will make your life easier.

I couldn’t wait to see this. I absolutely adore sprinkles!! I can’t wait to have some of this!
Thanks Cassie! Sprinkles make everything better!
This cake looks so good. You are one talented pastry chef! I love the colour of your butter cream and the sprinkles are decorated so perfectly. Love the look of the inside before the frosting too. MUST BE YUMMY!
You are too kind Ellen, thank you!
OH my, I am trying this next birthday we have. My husband and son always want a cookie cake. I just make a large one similar to the ones in the mall, but this is so much better!
Thanks Erin! So happy you’re going to try it
What a fantastic idea! I’m sure you could use all sorts of flavors of cookies to make different cakes! I wonder how the cookies do when the cake is cut? Would they crumble or would the buttercream help keep them soft?
Thanks Emily! The reason this cake works really well is because the sprinkle cookies are soft & chewy to begin with. The buttercream does help to keep them soft so it cuts beautifully!
Oh my god! This is the greatest cake I’ve ever seen! The only thing I love more than cake is cookies, and this brings those two together! This is way better than those thin, giant cookie cakes at the mall like you mentioned; this is a REAL cake.
You’re so sweet, thanks girl! This cake has your name written all over it
Wow! It looks so cute! And cookie cake sounds just great!
Beautiful work as always!

Thanks Michelle! The cake measures a little under 6 inches.
Wow! I’m facinated with your sophistication of the good ‘ole cookie! Love this idea, especially since it’s sprinkle cookies – I’m a sucker for sprinkles.

This is pure genius Meghan. I love that it’s a cookie cake. I love that it’s yellow. And I love the sprinkles.
Thanks girl! I was originally going to do pink (shocker), but so happy with the yellow!
Oh meghan! This is so beautiful… Sprinkles make everything so pretty and i love how it’s a cookie cake rather than a regular cake
Thank so much & I agree on the sprinkles!

Loving how beautiful this turned out! I honestly thought it was a cake for a second, then I read closer
I’m super inspired by your story, I was reading through your About section. I am about to graduate with my bachelors from the Culinary Institute of America, and I just started my blog several months ago, so hopefully I will have as much success with it someday as you have with Buttercream Blondie!
Best of luck to you in the future, and check out my blog if you get a chance!

I love your cookie cake idea! I’ll deliver if you will.
Deal
This is fantastic! I embarrassingly love the flat mall cookie cakes, and can only imagine how perfect this would be
Thank you!
WOW! Just stunning! I think I’d rather eat this one than any other kind of cake! Totally delish!
Thanks Lizzy!
Wow this cake is gorgeous! Love the cookie cake too. YUM!
What a super cute cake! Love it
Wow, this cake is amazing! Cookies used as layers-pure genious!! I feel so many ideas brewing
And I LOVE your shiny sprinkles amazing!
This cookie cake is absolutely stunning! What a clever idea to layer cookies and frost them with buttercream. Way better than the average cookie sheet cake any day.
Meghan, This gem is beautifully concocted from concept, to color and execution. I love how the satiny frosting preserves the cookie’s soft, chewy texture so that it works. Brava to you and your client for nudging you towards this spectacle!
I’m crazy about sprinkle cake, just like a kid, but this cake, oh, this cake blows me away!
You took a simple, lifeless cookie cake and made this masterpiece! Absolutely stunning Meghan!

Hi – I love this idea and my daughter wants it for her birthday in December, unfortunately her twin brother not so much into rainbow sprinkles as she is. Can I substitute mini chocolate chips instead? or would just chocolate sprinkles work? Thanks in advance for your help
Hi Stacey! I think you could use mini chocolate chips in place of the rainbow sprinkles. Chocolate sprinkles would be great too. Either way I think you’re good! Enjoy!
I was a 25 year pastry chef and I just wanted to compliment you on your beautifully decorated cake. Nice job. Will have to try your recipe.
What an awesome idea! Definitely a step above the normal cookie “cakes” that you find in the stores!
This is amazing! I love what a surprise it must be when you eat it too.
