Confetti Cake – moist and fluffy vanilla cake layers, lots of sprinkles and a whipped vanilla buttercream.
Best Birthday Cake
I’m not sure there’s anything more classic or more nostalgic than a classic Confetti Cake. Since the day Pillsbury came out with their hugely popular Funfetti Cake back in the 1950’s, it’s been a favorite for generations! What’s not to love? Vanilla cake, vanilla buttercream and lots of sprinkles!
Like many of you, I grew up on the boxed version of this cake. I loved it back then, but a few years ago came up with my own recipe. I originally posted it as my Fourth of July Funfetti Cake, and grew to love it even more!
In this first version of my Confetti Cake, I used my Classic White Cake and Vanilla Buttercream as the base. It’s super light and fluffy, and reminds me of my childhood. However, I’ve always felt like it could be better. As I’ve remade this cake over the years, I just kept thinking, I need to try this one again.
Confetti Cake
As I’ve been working on my cookbook (to be released later this year), I made a few changes to this recipe to make it even more memorable and delicious. In this updated Confetti Cake recipe, the cake is more of a vanilla cake than a white cake. It’s a little more moist, in my opinion, than my original version. And it also has a slightly stronger vanilla flavor to it as well.
The texture and flavor in this cake is so delicious and I’m so excited for you to try it!

- Use good quality pans like Fat Daddio.
- Spray your pans with nonstick spray and line with parchment paper.
- Don’t overmix your cake batter once you add the dry ingredients.
- Use room temperature wet ingredients.
- Use fresh baking powder.
- Bake until a toothpick inserted in the center of the cake comes out with a few moist crumbs on it.

Ingredients
FOR THE CAKE
- 1 cup (226 g) unsalted butter room temperature
- 1 3/4 cups (350 g) granulated sugar
- 1/3 cup (72.6 g) vegetable oil
- 3 large whole eggs room temperature
- 3 large egg whites room temperature
- 1/4 cup (60 g) sour cream room temperature
- 3 cups (345 g) cake flour
- 1 tablespoon (14 g) baking powder

- 1 cup (240 g) buttermilk room temperature
- 1 tablespoon (12 g) vanilla extract
- 1/4 cup (40g) rainbow sprinkles
FOR THE BUTTERCREAM
- 2 cups (452 g) unsalted butter chilled (I take the butter out of the fridge 30 minutes before I make my frosting)
- 6 cups (750 g) powdered sugar measured then sifted
- 4 tablespoons (57.75 g) heavy whipping cream
- 2 teaspoons (8.4 g) clear vanilla extract
- *This buttercream recipe makes enough to fill and cover your cake. If you want to add additional piping, you’ll want to make an extra ½ batch.
Instructions
FOR THE CAKE
- Preheat the oven to 325 degrees F. Prepare three 8-inch or four 6-inch round cake pans with non-stick spray, parchment paper on the bottom of the pan, and another coat of spray. Set aside.
- In a medium size bowl, whisk together the cake flour, baking powder and salt. Set aside.
- In the bowl of a stand mixer, fitted with the paddle attachment, beat the butter, oil, and sugar on high until fluffy and smooth, about 5 minutes.
- Add the eggs and the egg whites, one at a time to the bowl and beat on medium until well incorporated. Add the sour cream and beat on medium speed for a minute or so. It may look curdled, don't stress.
- Turn the mixer on low and add ⅓ of the flour mixture to the butter mixture and mix until fully incorporated. Then add half of the buttermilk and blend well, followed by another ⅓ of the flour mixture, the second half of the buttermilk and lastly, add the remaining flour mixture and mix until incorporated.
- Add the vanilla extract and beat on low until incorporated. Scrape down the sides of the bowl and mix on low for another 30 seconds. Fold in the sprinkles.
- Evenly distribute the cake batter among the three 8-inch or four 6-inch pans and bake for 23 to 28 minutes, until toothpick comes out with just a few moist crumbs on it.
- Remove cakes from the oven and let cool in pans for 10 minutes before inverting onto cooling racks.
- When cakes are completely cooled, I like to wrap each cake layer individually with plastic wrap and stick it in the refrigerator or freezer until I’m ready to frost. The cake will be easier to work with if it’s cooled a bit. If I’m making the cake a day or two before I actually need to frost it, I put it in the freezer to ensure freshness. If I’m frosting same-day, I’ll just put it in the refrigerator to chill until needed.
FOR THE BUTTERCREAM:
- In the bowl of a stand mixer fitted with a paddle attachment, cream the butter for about 2 minutes. This will soften the butter without it having to be warm.
- With the mixer on low speed, gradually add the sifted powdered sugar, one cup at a time, mixing a little in between each addition.
- With mixer on medium speed, add whipping cream, vanilla and salt.
- Turn the mixer to medium-high speed and beat for an additional 5 to 7 minutes. The frosting will become lighter in color and texture.
- Before spreading on your cake, spend a couple minutes mixing the buttercream by hand with a wooden spoon to push out the air pockets.
ASSEMBLY
- Place the first cake layer, top side up. Add about ¾ to 1 cup of frosting. Spread over the cake layer as evenly as possible. Make sure to get eye level with the cake to ensure the frosting is spread evenly over the cake.
- Repeat this step until you get to the final cake layer, which you will lay top side down.
- Apply a thin coat of buttercream around the entire cake to lock in the crumbs. Freeze for about 10 minutes.
- After the crumb coat is set, continue frosting and decorating the cake.
Hey Courtney, whenever i make this recipe the came shrinks substantially from the sides of the cake pan. It also shrinks when made into cupcakes and the cupcakes are so small. Any idea what I’m doing wrong? Thanks!
I’m sure you’re not doing anything wrong. It could be an issue with climate. Are you somewhere where there’s high humidity?
High humidity! What can I do?
You’ll want to add a few extra tablespoons to the cake batter to help with the extra moisture in the air.
It doesn’t say to add sprinkles to the buttercream but it’s in the photo. How many do you add? And do I need to worry about the colors bleeding at all in the icing?
My cakes did not rise
Could this be used for a sheet cake?
Yes!
How should I adjust this recipe for high altitude? First time baking in Denver after moving from the Midwest!
My recipe is already adjusted for high altitude since I’m in Utah!
Hi! I tried this recipe today and all my layers came out flat and thin. I live in South Louisiana. Super humid. Could this be why? What can I do next time to help the cake rise?
Shoot! So sorry to hear that. Yes, the humidity could be an issue. On rainy or muggy days,or just in high humid areas, when humidity is really high (70 % + ), your baking ingredients (i.e. flour, baking powder, baking soda, salt, sugar, cocoa powder, etc.) actually soak up the moisture from the air. This little bit of extra moisture can alter the texture and rise of your cakes. to help counterbalance the extra moisture in the air and in your ingredients, reduce the liquid by about 1/4 cup. Additionally, to ensure your cake layers rise well, be sure all the ingredients are room temperature.
When you say reduce the liquid – does this mean all wet ingredients or just the oil and buttermilk?
Shoot, I’m not sure what you’re referring to in this recipe.
Hi Courtney, If I were to add a filling between my layers, what would you recommend?
So many yummy options: an eggless cookie dough would be yummy, any kind of fruit compote, or even a whipped cream.
I love this cake! So yummy! Next time I make this, I want to make the buttercream a teal color. Any suggestions on how to get a teal color on your delish buttercream?
Hi! I’m in Nashville, TN and see your recipes are adjusted for high altitude (in Utah). Is there anything I need to do to adjust the ingredients to “low altitude?” We’re about 550’
Thanks!
No you’ll be totally fine!
Hi! How do you get the sprinkles incorporated into the frosting like that? Did you just fold them in by hand? I love how they are inside of the frosting instead of sitting on top!
Yes, I just folded in about 1/4 cup sprinkles into the frosting.
Can I make this gluten free?
Yep
How much cake batter do I need for 10 inch 4 layer cake? Do I just double the recipe? Thanks!
Yes, I would double the recipe for 4 10-inch layers.
I made this cake for my daughter’s 15th birthday. She had asked for a vanilla confetti cake, and this recipe seemed to be what she wanted.
Wow! The cake turned out just how I had imagined. It is rich, creamy and full of amazing flavor! I would recommend this to anyone looking for a slice of heaven☺️
Oh yay! I’m so thrilled you loved it!
So light and fluffy! I was sadly not able to try this in the layer cake form since it wasn’t for me, I only tried the scraps and it was so so good. Courtney‘s American buttercream is the best ever, its always my go to! I halved the recipe to make a 3 layer 4 inch mini cake and has no issues at all
Hi. 🙂 What is your favorite brand of sprinkles to use?
I like the jimmies from Orson Gygi.
Followed all directions. The cake didn’t rise much, certainly not like the photos. Also, making the frosting with cold butter meant I had lumps of butter in the frosting even after mixing it for 7 minutes.
Do you use a 1/4 cup of sprinkles in the icing as well? What brand of sprinkles do you use? Any tips for spreading the sprinkle buttercream?
Yes, I added some in the frosting but that’s totally optional. It does make it a little harder to smooth the sides, but it’s fun! I like jimmies from Orson Gygi.
I’m planning on making this today and then using for my daughter’s birthday party tomorrow. You mentioned that you would freeze the cake if not using that day. How would you then defrost it the day of the party? Just pull it out of the freezer in the morning?
Thanks!
Yes and move to the fridge. Take out of fridge about 4 hours before serving.
Exited to make this but I have a question. If I freeze it and then decorate it how long does it take to thaw and be ready to serve? Once decorate should I store in fridge or side to defrost?
Also my maiden surname is Rich 🙂
You should take it out of the freezer the morning of the event and put it in the fridge. Take out of fridge about 4 hours before event.
How much salt in the buttercream icing on the confetti cake. In instructions it says to add in the salt. There is no salt listed on the ingredient list. Can you answer quickly? I’m making the cake in 2 days for a birthday. Thank you.
Just a pinch
I absolutely love this cake. My son said it’s really good and he’s not a big cake person. It has the best texture and flavor of any confetti cake I’ve made. I didn’t use the frosting recipe but after making this cake and seeing how great it is, I’ll definitely try the frosting next time. Can’t wait to try more of your recipes.
