Happy Birthday to you, and you, and you over there, and your brother, and your brother’s son, and your sister’s cousin. And your neighbor that just turned 30. And your favorite blogger who turns 35 (huh!?) this year (that’s me). And your fiancé, Happy Birthday to that human, too.
I made us a go-to, vanilla buttermilk cake with the very best chocolate buttercream frosting. (Proof that it’s the best chocolate buttercream provided here). We’ve got 360 days and likely a mega amount of birthdays to celebrate with friends and family.
This cake is super versatile. It makes for a happy and humble single layer 9×13-inch cake, or a 2 layer 9-inch cake, or about 2 dozen cupcakes!
There are three secrets to a great birthday cake:
- Make it homemade. Not fancy-homemade. Just homemade. A single layer buttermilk cake in a glass baking dish? That’s lovely.
- Sprinkles. It’s a party. Even if people ‘hate’ their birthdays, they don’t hate cake and they don’t hate sprinkles. If they do… just get them a kitten and a puppy and throw confetti in the air and run away quickly.
- Always serve birthday cake with a greeting card. ‘I’m not a card person’ is a thing people say but a birthday is not a birthday without a proper, folded paper well-wishing.
Happy Birthday to you and yours, us and ours, them and theirs.
Simple, fool-proof (not that any of us are fools), buttermilk cake. Flour with baking powder, baking soda, and salt. Butter creamed with sugar and eggs. Vanilla extract and buttermilk. It’s so easy. If you put on some really good music, this is as painless and far more delicious than mixing together a boxed cake mix.
Fluffy butter creamed with sugar.
Eggs are added, beating for 1 minute between each egg addition.
The creamy yolks will make the cake golden yellow.
Dry ingredients whisked with leavening and salt is added to the egg and butter mixture.
It’s about to be cake!
Into the cake pans. A single layer or two round cake pans will do!
Baked to golden.
While the cake bakes, I make The Best Chocolate Buttercream. It’s creamy and fluffy and exactly what you want on top of a birthday treat.
Cooled, tender cake. Fluffy chocolate frosting. Birthday letters. Sprinkles. You’re so thoughtful. I hope people tell you that often.

A very happy birthday!
PrintEverybody’s Birthday Cake
- Prep Time: 20
- Cook Time: 30
- Total Time: 50 minutes
- Yield: 1
Ingredients
For the Cake
- 1/2 cup (1 stick) unsalted butter, softened
- 1 1/2 cups granulated sugar
- 3 large eggs
- 1 teaspoon pure vanilla extract
- 2 1/4 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 1/4 cups buttermilk
For the Chocolate Buttercream
- (double the frosting recipe for a layer cake of generously frosted cupcakes)
- 3/4 cup (1 1/2 sticks) unsalted butter, softened to room temperature
- 1/2 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 2 1/2 cups powdered sugar
- 1 teaspoon pure vanilla extract
- 2 tablespoons whole milk
- 1/3 cup plus 1 tablespoon heavy cream
- 1/3 cup Rich Chocolate Ovaltine powder
Instructions
- To make the cake, place a rack in the center of the oven and preheat oven to 350 degrees F. Grease and flour a 9×13-inch cake pan or 2 9-inch round cake pans. Set aside.
- In the bowl of a stand mixer fitted with a paddle attachment (you can also use a large bowl and electric hand beaters) cream together butter and sugar until light and fluffy, about 3 to 5 minutes.
- Stop the mixer and and scrape down the sides of the bowl. Beat in the eggs, one at a time, beating for 1 minute between each addition. Beat in vanilla extract.
- In a medium bowl whisk together flour, baking powder, baking soda, and salt. Add the dry ingredients all at once to the butter and egg mixture and beat on low until just combined. Add the buttermilk and beat on low for 1 minute. Increase the speed to medium and beat for 3 minutes more.
- Pour batter into prepared pan or pans. Bake for 25 – 30 minutes or until cooked through and the top springs back lightly when touch. Test the cake by inserted a skewer into the center of the cake. Cake is done when just a few crumbs are left on the skewer.
- Remove from the oven and allow to cool in the pan completely before frosting. If making a layered round cake, remove the cakes to a wire rack to cool completely. Let cool completely before frosting.
- To make the frosting, cream together butter, cocoa powder and salt. Butter mixture will be very thick. Turn off the mixer, scrape down the sides of the bowl.
- Add powdered sugar. Turn mixer on low and mix in powdered sugar while adding milk and vanilla extract. As the sugar incorporates, raise the speed of the mixer to beat the frosting. Beat until smooth, about 1 minute.
- In a 2 cup measuring glass, stir together heavy cream and Ovaltine. Turn mixer speed to medium and pour half of the cream mixture into frosting in a slow, steady stream. Stop the mister scrape down the sides of the bowl. Add remaining cream mixture or until you’ve reached your desired consistency. Beat until soft and creamy, about 1 minute.
- Store in an airtight container in the refrigerator or freezer. Bring to room temperature before frosting cakes and cupcakes.
- Slather cake generously with frosting. Decorate and sing happy birthday!

I think I need this cake simply because it’s Tuesday. No birthdays in sight, but I always need cake <3
Happy New Year, friend! xo

Today IS my birthday! Thanks Joy and cheers to the 10th anniversary of my 21st birthday!

Happy Birthday!

Is it possible to sub the “ovaltine” for something, I’m not sure that is something I’d buy or use again.
joythebaker
I think hot cocoa mix would also be lovely.
MaggieToo
Valerie, trust me — you WILL use that Ovaltine again after you taste this frosting. I’ve been making it almost to the exclusion of all other chocolate frostings since I met it here a while back. And I make a LOT of cakes. The Ovaltine isn’t expensive, and it keeps forever. It’s just amazing what a difference it makes in the flavor. Do try it!
Luba
Hey guys, an overseas girl here. How to sub Ovaltine?
Will Nesquik work? I get that Ovaltine is superb but we don’t have it here. :’-(
Thanks.
joythebaker
Nesquik will just not give you as much chocolaty flavor. It’s more sweet than chocolate usually.

I’m from Australia and I use Milo, a malted milk drink, which makes this icing DIVINE also.
Jenny
Wait, when you say “your fiance,” does that mean YOU have a fiance?!
joythebaker
No.
Jenny
hahah, okay, just checking! :)

Hi, Joy! Long time reader, love your writing and recipes! I have so many saved that I return to over and over (favorite is your peanut butter banana bread).
I’ve noticed the last few posts that I have to click from my reader (Feedly) over to your site to read them. Unfortunately, I browse most blogs on my phone and your site isn’t great for my browser on Android. Your posts look excellent on Feedly, easy to read, pictures sized well, but the experience is not ideal if I click over.
I don’t mean to complain and I’ll continue to read regardless, because your work is delightful, even when you’re giving me a recipe for something I would never eat (I’m a vegetarian, but read all your stuff through!), but I thought it was possible you’d accidentally changed a setting and didn’t realize it, or maybe did it on purpose but weren’t aware that your site doesn’t look great on all phones, so I thought I’d speak up.
Thank you for sharing so much of yourself with us! Wishing you much love in the new year!
joythebaker
Thanks for the comment Kate! When I updated my site last week, something went wonky with my RSS feed. I’m working to fix it! Thanks for the heads up and understanding.
Kate B
Oh, good, I’m so pleased! I fully understand the internet gremlins getting into the works and I wasn’t sure if it was something you’d done intentionally or a glitch. I hope I haven’t been the, like, 57th person to point it out to you! Thanks for understanding that it’s easier for some of us to access from RSS, even though I know it probably affects your metrics and any ads you might have running. I read everything you put up and I don’t mean to shortcut the backend of your site/business stuff! Continue the excellent work, friend!
Tori

Happy birthday! Looking forward to replicate this one :)

I always feel that cake tastes better out of a pan like that. It may not be the fanciest, but it sure looks delicious!
millie
oh man, that looks good. :)
Rena
Now I want to have exactly this cake for my birthday I have very soon :)

love love that you, Joy the Baker, deem a 9×13 cake in a pan an acceptable birthday cake. These days there is sooo much pressure to make it fancy! I’m making my nephews birthday cake and I will totally make this one!
