Where are all my funfetti cake friends out there? The friends who agree that sprinkles make everything better. I’ve got you covered today with a Homemade Funfetti Cake.

Ever since I made my moist vanilla cake, I’ve been tweaking the recipe for other flavors like a mimosa cake. This time, it’s funfetti. Lucky for you, I also have a funfetti poke cake recipe that is similar to this one.

What can you expect from this funfetti cake? It’s crazy moist, it’s a more dense, spongier cake and it’s bursting with vanilla flavor. It’s not overly sweet, so it can be topped with any variety of frosting recipes.

It would have been too easy for me to just throw some sprinkles into my original vanilla cake recipe, but like I mentioned before, I wanted to change it just a bit. Instead of milk, I opted for buttermilk. This gives the cake a more tender crumb, and also adds a bit of acidity or tanginess to the cake.

This cake batter is probably thinner than you’re used to, but it’s supposed to be. Since you’re adding the buttermilk at the same time as the dry ingredients, it’s important that you scrape down the bowl and stir it by hand a couple of times before you pour it in your pan. This will help ensure the batter is evenly mixed.

This funfetti cake recipe can be made as a cake and also as cupcakes. For the cake, you’ll use a 9″ by 13″ inch pan. If you choose to make funfetti cupcakes, this recipe will make a hefty 24 cupcakes with a little batter left over.

For the frosting, be sure you take the time to whip the butter prior to adding the powdered sugar, this will help build the light and airy structure needed for the frosting. You will notice the recipe calls for the frosting to be whipped for more than 5 minutes, this is not a mistake! I love the light and whipped texture. It should spread very nicely over top of the cake.

Homemade Funfetti Cake

  • Author: Beyond Frosting
  • Prep Time: 10
  • Cook Time: 30
  • Total Time: 40 minutes
  • Yield: 12-15 slices


This moist Homemade Funfetti Cake recipe is a slightly denser than average cake with a tight crumb made with buttermilk. It’s has a sponge like texture and it’s packed full of vanilla and sprinkles.  


  • 2 cups granulated sugar
  • ½ cup vegetable oil
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • ½ cup light sour cream
  • 2 ½ cups all-purpose flour
  • 3 teaspoons baking powder
  • 1 teaspoon salt
  • 1 ¼ cups buttermilk
  • 1/2 cup sprinkles


  1. Preheat the oven to 350°F.
  2. In a large mixing bowl, combine the sugar, vegetable oil, eggs and vanilla extract. Beat on medium speed until the eggs and oil are well incorporated and the batter is lighter in color, about 2 minutes. Scrape down the bowl as needed.
  3. Next mix in the sour cream and beat until well combined.
  4. Add half the flour followed by the baking powder and salt, and beat on low speed while pouring in half of the buttermilk and mix just until the flour starts to incorporate.
  5. Finally add the remaining flour, mixing on low speed while pouring in the remaining buttermilk and beating until all of the ingredients are well combined. Stir in the sprinkles.
  6. Use a spatula to scrape down the sides of the bowl and stir the batter from the bottom to the top to ensure it’s well mixed.
  7. Pour the batter in a 9-inch by 13-inch pan and bake at 350°F for 28-32 minutes, keeping a careful eye on the baking during the last few minutes. Remove from the oven and allow to cool completely.
  8. Test the cake for doness by inserting a toothpick into the center of the cake. If the toothpick comes out clean, you cake is done.


  • This cake is topped with a half batch of my Perfect Vanilla Frosting.
  • The batter will be quite thin. It’s important that you stir the batter after mixing, to ensure everything on the bottom of the bowl is well mixed.
  • This cake will not produce a very high rise but that’s okay!
  • This can easily be made into 24 cupcakes by using a large (3 tablespoon) cookie scoop. Bake for 16-20 minutes at 350°F
  • This cake can also be made without the sour cream, it will still be very tasty but it will not be as moist after 2 days.
  • I used an aluminum pan. Baking times will vary by pan type and true internal oven temperatures.

    Hi, I tried your recipe and I used glass pan and the cake was cracked on top. The taste was super good though. I don’t know what did I do wrong. Am I not supposed to bake it in the glass pan?

      Hi Pattira, I am not sure why that happened. I have not baked this recipe in a glass pan, but I suppose it could be part of the issue? You should have able to use one though.

    Hi, thanks for sharing this recipe. Just had one question. I used another recipe previously where the batter was as thin as this one and after baking all the sprinkles had fallen to the bottom and glooped together. Have you ever found that happen with this recipe? Any suggestions to avoid this? Thanks

    1. Beyond Frosting

      Hi Kyra, I don’t have the exact cup measurements off hand. I would start by adding 1 cup of batter to each pan and then see what you have left. Measuring the batter ad you pour is the best option to ensure evenly filled pans

    Is this recipe enough batter for 2 nine inch round cake pans? Also the last time I tried another funcetti recipe the sprinkles bled into the batter. Any suggestions? I am making a bunny cake for Easter and thought this would be yummy!


    1. Beyond Frosting

      Hi Carol, this batter would actually make closer to 3 layers in a 9-inch pan. It would be too much batter for only 2 layers. Also in regards to the sprinkles, be sure not to use non pareil, those will bleed. This batter is also a very wet batter and the results would be the same if you used non pareil
