Happy Birthday, to me!

How cliche is it to post a Funfetti Cake recipe on my birthday? It’s a bit over the top, but I don’t even care!

Now that I’m one year old, and wiser too, I’m choosing to share THE BEST Funfetti Cake with you! And in case you didn’t know, Funfetti Cake is like, the perfect birthday cake.

Funfetti Cake from Scratch

I tested this recipe 3 times. Yes, 3! I was determined to get this recipe *just* right. And I did!

This Funfetti Cake has the perfect amount of sprinkles, the crumb is just right, and it’s mighty tasty!

So tasty, you’ll NEVER make the dry and tasteless box cake mixes ever again.

The secret to achieving the genuinely sweet and “Funfetti” taste is to use clear vanilla extract.

For a show-stopping birthday cake, lets make a Funfetti LAYER cake!

How to make Funfetti Cake

  • Begin by sifting the dry ingredients together. Sifting the ingredients allows the baking soda, baking powder, salt, and flour to FULLY and evenly incorporate. Plus it gets rid of lumps that might be in the flour.
  • This recipe calls for CAKE FLOUR. I suggest you use cake flour. The protein content in cake flour is about 8% while all-purpose flour has a protein content of 13%. So ultimately, cake flour will give you a more light and tender cake. If you choose to use all-purpose flour I can’t guarantee the same result in the recipe. However, you’ll use 3 cups of all purpose flour rather than 3 1/4 cups + 2 Tablespoons of cake flour.

  • In large bowl, or bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar for 2-3 minutes. The butter and sugar will appear fluffy and smooth. This is an important step in cake making! Creaming the sugar and butter pushes air into the mixture and aids in leavening the cake (making it rise).
  • Next, add the eggs. You’ll do this one at a time. Beat for 30- 60 seconds after you’ve added each egg.
  • Add the vanilla extract.
  • With the mixer on low alternate adding the flour and buttermilk. So flour, buttermilk, flour, buttermilk, flour.
  • Mix until JUST combined! Don’t over-mix cake.
  • Add the sprinkles to the bowl and then gently fold them into the batter.

  • It doesn’t take long for the sprinkles to be evenly distributed. If you get carried away and start mixing the batter too much, the cake batter will start to turn gray… not pretty!
  • Evenly divide the batter amongst the 3 cake pans.

PRO TIP: I use my kitchen scale to divide the batter amongst the cake pans. This is the best way to get even layers!

I made this cake in 3 – 8 inch round cake pans. You could do this in 4- 6″ round cake pans. I haven’t tested the recipe with this cake size, so you’ll have to keep an eye on the oven to determine when the cake will be done.

The cake is done when a toothpick inserted in the center comes out clean.

Cool on a wire rack for 10 minutes and then turn the cakes out onto the wire rack and let them cool completely before frosting.

Bonus tip: This cake is DELICIOUS as is, however, if you’d like an extra moist cake, you can substitute some of the buttermilk for sour cream or plain greek yogurt. Do a straight substitution. This recipe calls for 1 3/4 cups buttermilk, so if you wanted to do the sour cream route I would try 1 1/4 cups buttermilk and 1/2 cup full fat sour cream. This will really up the moistness level… if you’re into that. ?

I should note, I didn’t make this cake with sour cream, so do it at your own risk! But, I’ve made multiple cakes with either sour cream or greek yogurt and they turn out beautifully!!

Funfetti Cake Frosting

All that’s left is to make the buttercream. Simply cream the butter until light and fluffy about 2-3 minutes.

Then add the powdered sugar, vanilla, salt, and heavy cream. Once the ingredients are added beat on high speed for another 2-3 minutes until the buttercream is fluffy and lighter in color.

Add more heavy cream as needed. The consistency of buttercream should be thick yet easily spreadable.

If you don’t have heavy cream, go ahead and use regular milk to make the buttercream.

Electric Pink food coloring for frosting the top of the cake. I love this brand of food coloring. It’s gel, and the pigment is insane! You can find a handful of beautiful colors here.
