Funfetti Birthday Cake

Celebrate in style with this Funfetti Birthday Cake made from scratch. It’s moist, and sturdy, and covered in sprinkle goodness for a beautiful cake perfect for any celebration or birthday.

When making this particular cake, I highly recommend lining the bottom of the cake pan with parchment paper. This will ensure that your cake will come out of the pan in one piece. I have used both butter and nonstick cooking spray to grease the pan on this, and both worked out just fine.

This recipe is written for 3 9-inch layers. A three tiered cake produces the ideal cake to frosting ratio. A 9-inch pan is a standard size. 8-inch and 10-inch pans will require adjustments to the recipe so adjust at your own risk.

Do not over bake this cake. Over baking a white or vanilla cake is the fastest way to dry it out. You can test your cake for doneness by inserting a toothpick into the center. If it comes out clean your cake is done. I prefer to tap the top of my cake. I can feel whether or not the cake is done by seeing if it jiggles at all. If it jiggles, there is still liquid in the center.

Q: Can this recipe be made into cupcakes?

A: Why yes it can! They are baked at 325 degrees for 20-22 minutes and this recipe makes about 36 cupcakes.

Q: Can I make this recipe into only two layers?

A: Yes you can, you’ll need to divide the recipe by 2/3rds. But no, I won’t do the math for you. I truly believe that the best cakes with the ideal frosting to cake ratio must be 3 layers.

Q: Do you have a substitute for eggs?

A: There are numerous options for substituting eggs in baking recipes. You can always try using one of those.

Q: What if I don’t have buttermilk? Do I have to use it?

A: Buttermilk reacts with the baking powder in this recipe to give the cake volume. To learn all about buttermilk, as well as learn how to make a quick and easy buttermilk substitute, please read this post.

Q: Can I use a different pan size?

A: You are certainly welcome to try, but you’ll need to adjust cooking times and be careful as to how much you fill the pan. This recipe is written for 9-inch round pans, which is a standard size and is meant to be eaten as a 3 layer cake.

Q: Can I use a different frosting?

A: You certainly can!

Q: Can I make this recipe gluten free?

A: Use gluten free flours at your own risk. Not all gluten free flours are equal and most don’t work as a straight forward substitute for all-purpose flour. I have not tested any gluten free flours in this recipe as I do not have Celiac’s disease.

Q: Do I have to coat the outside with sprinkles?

A: Nope! You can decorate the cake however you would like.

Q: Can I add sprinkles to the frosting for a funfetti frosting?

A: Yes! Once your frosting is made, simply fold in your sprinkles gently. This will keep the sprinkles from bleeding out their colors into the frosting.

Q: Can I use non-pareil sprinkles?

A: No, I don’t recommend it as they bleed out their colors and won’t produce the ideal result for a funfetti cake.

In the photos and video I have covered my cake completely with sprinkles. This required almost 2 cups of additional sprinkles. I will warn you that it can get downright messy so have a vacuum or broom handy. It’s a beautiful result, but it can get a bit crazy.

Servings: 20 Servings or 1 3-layer cake



  • 1 cup salted butter softened
  • 1 1/2 cups sugar
  • 2 teaspoons vanilla extract
  • 3 1/2 cups flour
  • 4 teaspoons of baking powder
  • 1/2 teaspoon salt
  • 3 large eggs
  • 1 1/2 cups buttermilk
  • 1 cup sprinkles


  • 1 1/2 cups softened butter
  • 8 ounces cream cheese softened
  • 3 teaspoons vanilla extract
  • 6 cups powdered sugar
  • 2 tablespoons milk
  • 2 cups sprinkles for decorating


  • Grease three 9-inch pans. Line the bottom with parchment paper. Preheat an oven to 350 degrees F.
  • In a large mixing bowl, use a hand mixer to cream the butter and sugar together. Beat in vanilla extract.
  • Use a fork to combine the eggs and buttermilk together in a bowl or 2 cup liquid measuring cup. Set aside.
  • In another mixing bowl stir together flour, baking powder, and salt.
  • Add 1/3 of the dry ingredients to the butter mixture and mix in until just combined. Add in half of the milk mixture and combine. Add in another 1/3 of the dry ingredients until combined followed by the remainder of the buttermilk mixture. Add in the remainder of the dry ingredients and mix with the hand mixer until just combined, using a rubber spatula to scrape the sides and bottom to make sure everything is mixed in. Gently stir in sprinkles. Do not over stir or colors will bleed.
  • Divide the batter among the three prepared pans. Bake at 350 for 25 to 30 minutes. Let sit in pans for 5 minutes and then transfer to a wire rack to cool completely before layering and frosting.
  • To make frosting, beat softened butter together with cream cheese and vanilla extract and 2 cups powdered sugar until light and fluffy.
  • Slowly add in remainder of powdered sugar and use milk to thin as needed. Frost and assemble cake layers with frosting in between, and to cover the outside. Decorate with additional sprinkles.
