  • Cake Flour: This is the key to getting the cake texture just right.

  • Baking soda: The baking soda adds in tenderness to the texture.
  • Salt: The salt will enhance the flavors of all of the other ingredients.
  • Buttermilk: You can buyt buttermilk from the store or you can make your own using this Buttermilk recipe!
  • Milk: 1% or 2% milk works fine! Use whatever you have on hand.
  • Clear Vanilla: The secret ingredient that will make this recipe taste

Homemade Cake Recipe

This funfetti cake recipe only takes about 30 minutes to put together, and the rest of the time is spent baking in the oven! Try it out, and you will never go back to a box cake mix again!

  1. Preheat oven and grease pans: Preheat the oven to 350°. Grease two 8-inch round cake pans and set aside.
  2. Whisk: In the bowl of a stand mixer whisk together the flour, sugar, baking powder, baking soda and salt..
  3. Add wet ingredients: Add the buttermilk, milk, vanilla, and oil to the bowl. Use the paddle attachment to mix on medium low until just barely fully combined. Using a rubber spatula, scrape down the sides and bottom of the bowl.
  4. Whip egg whites and fold in with sprinkles: In a medium bowl whip the egg whites until medium stiff peaks form. Gently fold the egg whites into the cake batter until just a few streaks of egg whites remain. Add the sprinkles and fold into the batter until no streaks of egg whites remain and the sprinkles are evenly distributed.

Let’s Bake a Cake!

  1. Bake: Separate the batter evenly into the two prepared cake pans. Bake for 30-35 minutes, until a toothpick comes out clean from the center or the center of the cake springs back when gently pressed.
  2. Cool: Let the cakes cool in the pan for 5 minutes before inverting upside down on a cooling rack. This will help the tops of the cakes flatten so they are easier to frost.
  3. Make Ahead (Optional): This step is optional but I like to make my cake rounds a day ahead so I can wrap them in plastic wrap and chill them in the fridge overnight. Frosting cold cakes is much easier than frosting freshly baked cakes. You can also store them in the freezer and frost them while frozen.


  1. Beat butter: In the bowl of a stand mixer, use the paddle attachment to beat the butter until smooth and creamy.
  2. Mix with the rest of the ingredients: Add in the powdered sugar, salt and vanilla. Mix on low until the powdered sugar is sufficiently absorbed by the butter and wont make a mess when the speed is increased. Increase the speed to medium high and beat for 2 minutes. Scrape down the sides and bottom of the bowl and add the milk. Mix on medium until smooth.
  3. Tint: You may tint the frosting your chosen color or leave it white for your funfetti cake.

Don’t Have Cake Flour? Make Your Own!

Don’t worry if you don’t have any cake four on hand for this funfetti cake! You can easily make your own in less than 5 minutes with only two ingredients: cornstarch and all-purpose flour.

  • To make 1 cup of cake flour: Take your all purpose flour and measure out 1 cup. Remove 2 tablespoons of the flour and place the rest of the flour in a bowl. Add 2 table spoons of cornstarch to the flour in your bowl. Whisk together and use as a substitute for 1 cup of cake flour. Repeat until you have the amount that your recipe calls for.

Funfetti Cake Tips

When choosing sprinkles for funfetti cake choose only sprinkles that are jimmies or quins. These sprinkles are much less likely to bleed in your batter. Do not use nonpareils (the little round rainbow sprinkles) because those will bleed and streak your batter.

Can You Make this Cake Ahead of Time?

Yes! I actually like to make the funfetti cake ahead of time and frost it later. I like to make my cake rounds a day early so I can wrap them in plastic wrap and chill them in the fridge overnight. Frosting cold cakes are much easier than frosting freshly baked cakes. You can also store them in the freezer and frost them while frozen.
