Funfetti Cake

I can’t think of a more fun birthday cake than funfetti cake y’all. And I have the very best recipe for it. I kept testing the cake until I nailed that fluffy moist texture a vanilla based cake should have (my trick is using oil and butter!) plus I jazzed it up with colorful sprinkles throughout. Then I keep it simple with a classic vanilla American buttercream that pairs perfectly for it. Every time I make it, it reminds me of my childhood, and I seriously get a kick out of it.

How to Make Funfetti Cake

Eggs being added to funfetti cake batter

Step 1: In the bowl of your stand mixer, fitted with the whisk attachment, place oil and butter and mix on high for 2 minutes. Reduce the speed to medium and slowly add in sugar. Then return speed to high and mix for an additional 4-5 minutes, until very pale yellow and fluffy. Next, add eggs one at a time, combining well after each addition, and scraping down the bowl as needed.

Step 2: Reduce your mixer speed to low and slowly add in flour, baking powder, salt, and baking soda. Mix until just combined, being careful not to overmix. Lastly, add in sour cream, milk, vanilla, and sprinkles and mix on low until just combined. Turn off mixer.

Step 4: Place in a preheated 325°F oven to bake for 18-25 minutes or until a toothpick inserted into the center of the cake comes out just barely clean. Switch the racks the pans are on halfway through baking. Be careful not to over bake! Remove the cakes from the oven and cool in the pans for 10 minutes. Then remove cakes from the pan and set on wire racks to cool completely, for about 20 more minutes.

Ingredients

For Cake

  • 2/3 cup vegetable oil
  • 1/3 cup 5 1/3 tablespoons unsalted butter, room temperature
  • 1 ½ cup granulated sugar
  • 3 large eggs room temperature
  • 2 ¾ cups all-purpose flour sifted
  • 1 ½ teaspoon baking powder
  • 1 teaspoon kosher salt
  • ½ teaspoon baking soda
  • 1 ¼ cup sour cream room temperature
  • 1/3 cup whole milk room temperature
  • 1 tablespoon vanilla extract
  • ¾ cup sprinkles*

For Buttercream

  • 2 cups unsalted butter softened
  • 1 teaspoon kosher salt
  • 5 3/4 cups powdered sugar
  • 4 1/2 tablespoons heavy cream
  • 1 tablespoon vanilla extract
  • Additional sprinkles for garnish

Instructions

For the Cake

  • Preheat your oven to 325°F and place racks in the two middle positions. Prepare three 8-inch round cake pans with nonstick baking spray, then a round of parchment paper, and another layer of spray.
  • In the bowl of your stand mixer, fitted with the whisk attachment, place oil and butter and mix on high for 2 minutes. Reduce the speed to medium and slowly add in sugar. Then return speed to high and mix for an additional 4-5 minutes, until very pale yellow and fluffy.
  • Next, add eggs one at a time, combining well after each addition, and scraping down the bowl as needed.
  • Reduce your mixer speed to low and slowly add in flour, baking powder, salt, and baking soda. Mix until just combined, being careful not to overmix.
  • Lastly, add in sour cream, milk, vanilla, and sprinkles and mix on low until just combined. Turn off mixer.
  • Evenly divide batter among the three prepared pans. Place in the oven to bake for 18-25 minutes, or until a toothpick inserted into the center of the cake comes out just barely clean. Switch the racks the pans are on halfway through baking. Be careful not to over bake! (Begin checking for doneness around 16 minutes, because everyone’s oven is different.)
  • Remove the cakes from the oven and cool in the pans for 10 minutes. Then remove cakes from the pan and set on wire racks to cool completely, for about 20 more minutes.

For the Buttercream

  • While the cakes are cooling, add butter, powdered sugar, and salt in the bowl of your stand mixer, fitted with the whisk attachment. Mix on low until the powdered sugar is incorporated.
  • Then, increase the mixer speed to high until the mixture turns light fluffy. Add the heavy cream and vanilla and mix until smooth and fragrant.

To Assemble

  • Place the first layer of cake in the center of your cake plate/stand. Spread ¼ of the buttercream on top and smooth with an offset spatula. Place the second layer of cake and ¼ of the buttercream.
  • Place the final layer of cake on top and spread ¼ of the buttercream on top of the cake, allowing a little to hang over the edge. Spread the remaining ¼ of the buttercream around the sides of the cake. Smooth evenly, then sprinkle the top with sprinkles. Slice and enjoy!

Notes

The best sprinkles to use for baking are the long sprinkles (aka jimmies). Do not use nonpareils for this.
How to Store
    • Room Temp: Keep it in a cake cover. They will last for up to 3 days.
    • Fridge: You can refrigerate the cake up to 5 days but cut slices and serve at room temp.
    • Freezer: Freeze layers unfrosted for the best results. Wrap with plastic wrap then cover in foil. They will last for up to 3 months.

Recipe Tips

  • Pick the right sprinkles: I love using the long, skinny rainbow sprinkles (aka jimmies) you find in the baking aisle of just about any grocery store. The texture and colors are perfect for this cake. Don’t grab the nonpareils for this.
  • Prevent color bleeding: Sometimes, the color coating on the sprinkles can bleed into the cake. To prevent this, very gently folding in the sprinkles. If you overmix the batter after adding them, it will change the batter color. 
  • Be patient: If you don’t wait until the cake is completely cool, the frosting will run right off. You need a healthy layer of frosting for those extra sprinkles to sit on.
