Inspired by the famous Milk Bar bakery in New York, this is my easy, homemade version of their popular Milk Bar Birthday Cake. With three layers of soft funfetti cake, dreamy vanilla buttercream and crunchy cookie crumbs, it’s perfect for birthdays, parties and celebrations!
Say hello to the perfect birthday cake 💜
My easy, copycat version of the famous Milk Bar Birthday Cake. It’s dreamy and creamy and filled to the brim with sprinkles. There’s three layers of funfetti cake sandwiched with the fluffiest vanilla frosting on the planet. And don’t even get me started on those shortbread cookie crumbs!
It was the perfect way to wish my baby girl a happy first birthday this month! 🥳
If you’ve been around these parts for a while, you’ll know that I’m a big fan of Christina Tosi and her famous New York Bakery, Milk Bar. Her amazing baked goods have been the inspiration behind so many of my recipes, like my Peanut Butter Cake, my Corn Cookies and my Birthday Cake Truffles.
I’ve also been lucky enough to taste her baked goods in both New York and Los Angeles (including every flavour of cookie on offer) AND do a cooking class at her Melrose Avenue store. What did we make? The famous Milk Bar Birthday Cake, of course!
So today, I’m putting on my pink headband and channeling my inner Christina, to bring you my simple, homemade version of Milk Bar’s Birthday Cake. It has all the elements we know and love from Milk Bar (like cookie crumbs and a milk soak) but it uses regular, everyday ingredients.
Why you will love this cake
- It looks incredible (c’mon, what a showstopper)
- It’s surprisingly simple to assemble
- It features the best vanilla frosting I’ve ever had
- It tastes even better than it looks
Tell more me about this cake
This gorgeous birthday cake features three layers of funfetti cake. In true Milk Bar style, it’s made using one sheet pan, rather than multiple round cake pans (more on that below). I’ve used my favourite buttery, Funfetti Cake recipe, that produces a soft and fluffy vanilla cake every time.
Next, is that vanilla buttercream. But while I love my regular buttercream frosting, we’ve made it even more special by swapping milk for Greek yogurt. The real Milk Bar recipe has cream cheese in the frosting, so this is our easy way of getting that similar tang. Another secret ingredient in our frosting is a hint of baking powder. Believe it or not, this helps make the lightest, fluffiest frosting ever. This frosting is so good, you’ll find yourself licking the bowl clean.

And then there’s those crunchy, crispy cake crumbs. These little funfetti shortbread crumbs take only minutes to make but they enhance the sweet, buttery, vanilla flavour profile we’re going for here. And they provide a unique textural element to the cake. We’re obsessed with them (and have used them here, here and here).
And even made a chocolate version for my Chocolate Cherry Cake.

What special equipment will I need?
- One quarter sheet pan (9 by 13 inch)
- 6-inch cake ring
- A sheet of acetate (at least 6 inches high)
So, How do I make a Milk Bar-inspired cake?
It starts with a quarter sheet pan. That’s right, this cake, just like my Raspberry Ripple Cake, is not made using regular round cake pans. Instead we use a sheet pan to make one large cake. Then we use a six inch cake ring to cut out three layers. It makes baking and layering the cake quick and easy.
We then use a sheet of acetate to line the inside of the cake ring. This will allow us to build the cake inside the cake ring, going nice and tall, and keeping all your frosting and fillings inside. The cake then goes into the fridge until you are ready to unwrap and present your masterpiece.
Wait, how do I get three cake layers?
One thing we learnt at Milk Bar is that when you are creating a cake like this, not every layer has to be perfect. In fact, the bottom layer is typically made from two half moons cut from the leftover cake, so you’ll get two perfect rounds and one you’ll have to piece together. But don’t worry, no one will know! See below diagram.
frequently asked questions
Yes! You can use two 8 inch cake pans or three 6 inch ones.
I recommend using good quality rainbow jimmy sprinkles. Don’t use nonpareils as they typically bleed in the cake batter.
Yes please do. It adds moisture and flavour, and will prevent your cake from drying out in the fridge.
This cake will keep well in the fridge.
Making this as a first birthday cake?
When I made this for Lucy’s 1st birthday, I omitted the crunchy cookie crumbs between the layers, and only placed them on top. That way she could easily eat a slice! The extra cookie crumbs will keep well in an airtight container at room temperature for 5 days.

Fluffy vanilla buttercream
- 230 grams (1 cup or 2 sticks) butter, room temperature, roughly chopped
- 2 teaspoons vanilla extract
- 500 grams (4 cups) icing sugar or powdered sugar, sifted
- 2 tablespoons full fat Greek yogurt or sour cream
- 1–2 tablespoons full fat or whole milk, room temperature
- 1/8 teaspoon baking powder
Milk soak
- 60 ml (1/4 cup) full fat or whole milk
- 1/2 teaspoon vanilla extract
Instructions
- Funfetti cake
Grease and line a quarter sheet pan (9 by 13 inches) with baking or parchment paper. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. - In a large mixing bowl, add butter, sugar and vanilla and beat with an electric mixer on medium speed until pale and creamy. Add eggs, one at a time, and beat after each addition.
- In a separate bowl, add flour, baking powder and salt, and whisk briefly. Add half of the flour mix and all the milk and beat on a low speed until combined.
- Add remaining flour mix and sour cream and continue to mix on a low speed until just combined and a thick, creamy cake batter forms. Gently fold in sprinkles by hand, being careful not to overmix.
- Pour cake into prepared pan and smooth the top. Bake for approximately 25-30 minutes or until golden and a skewer inserted in the middle comes out clean. Set on a wire rack to cool completely.
- Cookie crumbs
Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. - In a large mixing bowl, add flour, sugar and cornflour. Whisk together. Pour over melted butter, along with the vanilla, stir briefly. Add sprinkles and then stir until it forms wet crumbs that look like wet sand.
- Pour onto a baking tray lined with baking paper and spread out into one layer. Bake for 10 minutes, then leave to cool completely.
- Vanilla frosting
Place butter in a large mixing bowl. Beat with an electric mixer on medium speed for 1-2 minutes until butter is smooth and creamy. - Add vanilla and 125 grams (1 cup) sugar. Beat on a low speed to combine, then turn up the speed to medium and mix for 30 seconds. Next, add 250 grams (2 cups) sugar, along with the Greek yogurt.
- Beat on medium speed until combined. Scrape down the sides of the bowl. Add final 125 grams (1 cup) sugar, milk and baking powder. Beat on medium speed until frosting is fluffy and creamy.
- Assemble cake
Gently remove cooled cake from pan and remove baking paper. Cut out three 6-inch layers using a 6-inch cake ring. Note the diagram below – you’ll get two whole layers and then two halves. - Place a 6-inch cake ring on a cake board or plate. Line the inside of the cake ring with a sheet of acetate. Place the two half pieces of cake at the bottom. Press down the cake firmly. If there are any gaps, use extra cake scraps to fill in the holes and press down very firmly to make one even layer.
- Spoon 2-3 tablespoons of the milk soak (milk and vanilla combined) over the first cake layer. Add a few tablespoons of vanilla buttercream and spread into one layer. Scatter over a handful of cookie crumbs. Add a few extra tablespoons of frosting on top. You don’t need to completely cover the crumbs.
- Add another layer of cake and press down firmly. Spoon 2-3 tablespoons of the milk soak over the cake layer. Add a few tablespoons of vanilla buttercream and spread into one layer. Scatter over a handful of cookie crumbs. Add a few extra tablespoons of frosting on top.
- Add final cake layer and press down firmly. Add remaining buttercream and scatter over cookie crumbs. Place cake in the fridge for at least 1 hour to set.
Notes
Cake pans: You can use two 8 inch round cake pans or three 6 inch round cake pans if you prefer.
Sprinkles: I recommend using good quality rainbow jimmy sprinkles. Don’t use nonpareils as they typically bleed in the cake batter.
Barry says
How can a 6 inch cake serve 12-14? Must be v small servings! Looks great and I want to make this for my wife’s birtday. Can you recommend a brand of sprinlkes for the cake mixture? I tried something like this before and it didn’t really work, with no real colour to she sponge.
Jessica Holmes says
Hi Barry, I know what you mean, but since it’s very tall, the slices can be quite thin. And you can slice it into long rectangles instead of triangles to get more out of it. I used sprinkles I bought in the USA, but any jimmy sprinkles should work. I hope your wife loves it!
Kelly says
For the butter for the cookie crumbs and frosting, does that call for salted or unsalted? 🙂 Can’t wait to make this recipe!!!
Jessica Holmes says
Hi Kelly! I prefer to use salted but it’s up to you! Either will work fine.
Bacon says
Can this be turned into cupcakes??
Jessica Holmes says
Absolutely!
Jackie says
Delicious! Made this yesterday and it tasted wonderful and looked beautiful. Love your site and recipes.
Jessica Holmes says
Aww so happy to hear that Jackie!
Katelyn Leaver says
Im making this cake in a very large scale, out of two cakes to feed around 60 people. I read that it freezes well. Does the frosting also freeze well? Once deforested do I re whip? Thanks. Or how do you sudjest freezing it?
Jessica Holmes says
Yes you can definitely freeze the frosting. To use it, bring it back to room temperature, add a tiny bit of milk and beat it again using an electric mixer just until smooth and creamy.
Caroline says
Hi love the recipe! Just wondering why you need greek yogurt/sour cream and why there is no brown sugar anywhere?
Jessica Holmes says
So glad you enjoyed it Caroline. The acidity and fat in the yogurt/sour cream will help keep the cake extra moist. And I preferred using caster sugar instead brown sugar to keep the cake similar to a boxed vanilla cake in flavour and colour.
Polly says
This is such a fun and delicious cake which is perfect for a birthday. I made the 2 layer 8″ version and the off cuts are in the freezer. The frosting is amazing!!
Jessica Holmes says
So glad you enjoyed it Polly! Thank you for your kind feedback!
Lisa says
Hi. What would be the best low fat substitute for the 4+ sticks of butter this recipe calls for? Meaning, to keep the taste as good and similar as possible, what would your recommendation me of someone does not want the fat/saturated fat of all that butter?
Jessica Holmes says
Hi Lisa, I’m sorry but I can’t offer a substitute for the butter in this recipe. It really is key in making it taste so good! And I haven’t tested the recipe with any alternatives.
Michelle says
Please can you tell me how many people this cake is intended for
Jessica Holmes says
Hi Michelle, depending on how big you like your slices, I’d say 12-14 people.
Stephanie says
Can you freeze the cake layers until ready to assemble? I want to bake the cake a week in advance.
Jessica Holmes says
Absolutely! The cake itself will freeze well.
Derval says
Hi Jessica, I’m making this a week in advance, can i/should I make the whole thing assembled and freeze or what would be best?
Jessica Holmes says
Hi Derval, yes you can or you can simply make the cake ahead of time and frost and assemble the day of serving.
Ameera Khorakiwala says
Hi Jess,
If I plan to use 2 8 inch baking tins instead, what adjustments should I make for oven temperature and baking time?
Thank you in advance!
Jessica Holmes says
Hi Ameera, time and temperature will be the same. Just check if the cakes are done by inserting a skewer into the centre, when it comes out clean – you’re good to go!
mirlay says
Hola, me srugen dos dudas.
La primera es que los ingredientes dicen levadura y en el paso a paso dice polvo de hornear ¿cual se usa realmente?
La segunda es si se podria sustituir el yogurt por queso crema en la crema de mantequilla.
Jessica Holmes says
Hi, I’m sorry I can’t see anywhere it says yeast, it’s definitely baking powder that’s needed. And using cream cheese won’t be the same but it’ll still work.
Kristy says
Hello! So excited to make this cake tomorrow!
I have 3, 6inch pans I think I’m going to try to use. Just curious if i should pour less batter in them because with the sheet pan you would have all that leftover cake… so I would think the 6 inch pan cakes would be too think if I use all the batter? Also, would you change the bake time/temp?
Thanks 😊
Jessica Holmes says
Hi Kristy, I’m excited you are going to try this one! That is true that there is a bit more leftover cake doing the sheet pan method, but using your three 6-inch pans should be ok – the layers will just be slightly thicker. I’d still check them around the same time, but just do the skewer check. You’ll know they’re ready when it comes out clean. Hope you love it!
Josh says
This cake was epic! I couldn’t stop eating that frosting.
Jessica Holmes says
So glad you enjoyed it! And yes the frosting is everything!
Mufeedha says
Hi Jessica,
This recipe looks delicious! I noticed that you mentioned that this cake keeps well in the fridge – does that mean it can be made 1 or 2 days before and stored in the fridge? Thanks!
Jessica Holmes says
Yes you could do that! A day in advance would be fine!
Anahita says
Definitely been waiting for this recipe to try it after seeing it on your instagram multiple times! cant wait to make this next week :)))
Jessica Holmes says
Yaaay! I hope you love it!
Edgar says
Thanks for this formula! You Helped me with very important dinner party! What show stopper of a cake!
Jessica Holmes says
Brilliant! Love that!
