Turn any moment into a celebration with my moist and fluffy Confetti Bundt Cake and Vanilla Buttercream.

Confetti (Funfetti) Bundt Cake

I’m not sure there’s anything more classic or more nostalgic than a classic Confetti Cake. Since the day Pillsbury came out with their hugely popular Funfetti Cake back in the 1950’s, it’s been a favorite for generations! What’s not to love? Vanilla cake, vanilla buttercream and lots of sprinkles!

Like many of you, I grew up on the boxed version of this cake. I loved it back then, but a few years ago came up with my own recipe. I originally posted it as my Fourth of July Funfetti Cake, and grew to love it even more!

In this first version of my Confetti Cake, I used my Classic White Cake and Vanilla Buttercream as the base. It’s super light and fluffy, and reminds me of my childhood. However, I’ve always felt like it could be better. As I’ve remade this cake over the years, I just kept thinking, I need to try this one again.

When I worked on my first cookbook, “CAKE, by Courtney,” I made a few changes to this recipe to make it even more memorable and delicious. In this updated Confetti Cake recipe, the cake is more of a vanilla cake than a white cake. It’s a little more moist, in my opinion, than my original version. And it also has a slightly stronger vanilla flavor to it as well.

The texture and flavor in this cake is so delicious.

I know you’ll enjoy it in this bundt pan version too!

My Favorite Bundt Pan

The best bundt pan, in my opinion, is the Nordic Ware Anniversary Pan. It’s plenty big for any recipe, bakes your cakes beautifully, and makes for an easy release!

My Go-To Tips for Making Cake

Don’t forget to follow my go-to tips for getting your cakes to rise and bake well:

  • Preheat your oven for 30 minutes prior to baking.
  • Use good quality pans like Fat Daddio.
  • Beat the butter, sugar, and oil on medium-high until fluffy and smooth.
  • Spray your pans with nonstick spray and line with parchment paper. 
  • Don’t overmix your cake batter once you add the dry ingredients.
  • Use room temperature wet ingredients.
  • Use fresh baking powder.
  • Bake until a toothpick inserted in the center of the cake comes out with a few moist crumbs on it.

Ingredients
  

FOR THE CAKE

  • 1 cup (226 g) unsalted butter room temperature
  • 1 3/4 cups (350 g) granulated sugar
  • 1/3 cup (72.6 g) vegetable oil
  • 3 large whole eggs room temperature
  • 3 large egg whites room temperature
  • 1/4 cup (60 g) sour cream room temperature
  • 3 cups (345 g) cake flour
  • 1 tablespoon (14 g) baking powder
  • 1 teaspoon (6 g) salt
  • 1 cup (240 g) buttermilk room temperature
  • 1 tablespoon (12 g) vanilla extract
  • 1/4 cup (40g) rainbow sprinkles

FOR THE BUTTERCREAM

  • 2 cups (452 g) unsalted butter chilled (I take the butter out of the fridge 30 minutes before I make my frosting)
  • 6 cups (750 g) powdered sugar measured then sifted
  • 4 tablespoons (57.75 g) heavy whipping cream
  • 2 teaspoons (8.4 g) clear vanilla extract
  • *This buttercream recipe makes enough to fill and cover your cake. If you want to add additional piping, you’ll want to make an extra ½ batch.

Instructions
 

FOR THE CAKE

  • Preheat the oven to 325 degrees F. Prepare a 12-cup nonstick bundt pan by spraying it with nonstick spray and then coating the sides with flour. Set aside.
  • In a medium size bowl, whisk together the cake flour, baking powder and salt. Set aside.
  • In the bowl of a stand mixer, fitted with the paddle attachment, beat the butter, oil, and sugar on high until fluffy and smooth, about 5 minutes.
  • Add the eggs and the egg whites, one at a time to the bowl and beat on medium until well incorporated. Add the sour cream and beat on medium speed for a minute or so. It may look curdled, don't stress.
  • Turn the mixer on low and add ⅓ of the flour mixture to the butter mixture and mix until fully incorporated. Then add half of the buttermilk and blend well, followed by another ⅓ of the flour mixture, the second half of the buttermilk and lastly, add the remaining flour mixture and mix until incorporated.
  • Add the vanilla extract and beat on low until incorporated. Scrape down the sides of the bowl and mix on low for another 30 seconds. Fold in the sprinkles.
  • Pour the cake batter into the prepared bundt pan and bake for 50 to 60 minutes. The cake is done when a toothpick inserted in the center of the cake comes out with a few moist crumbs on it.
  • Let the bundt pan cool completely in the pan before inverting onto your cake stand.

FOR THE BUTTERCREAM:

  • In the bowl of a stand mixer fitted with a paddle attachment, cream the butter for about 2 minutes. This will soften the butter without it having to be warm.
  • With the mixer on low speed, gradually add the sifted powdered sugar, one cup at a time, mixing a little in between each addition.
  • With mixer on medium speed, add whipping cream, vanilla and salt.
  • Turn the mixer to medium-high speed and beat for an additional 3 to 5 minutes. The frosting will become lighter in color and texture.
  • Before piping onto your cake, spend a couple minutes mixing the buttercream by hand with a wooden spoon to push out the air pockets.

    Made this tonight and WOW. Blew our minds! The cake turned out so moist and fluffy and flavorful. I honestly could have eaten the cake without frosting which is something I would never normally say. But the buttercream frosting turned out amazing too and complemented the cake really well. I normally don’t like homemade buttercream frostings but this one was so good! My husband who normally is underwhelmed by vanilla cake/frosting went back for a second piece – even he loved it. My 5 year old son requested vanilla cake and vanilla frosting for his birthday celebration tonight and I’m so glad I went with this cake and frosting! Thank you, Courtney!

    1. Yay I’m so glad!!

    I don’t have a Bundt pan yet but want to try this cake. What size of cake pans and how many layers would you suggest instead? Still bake at 325? For how long? Thanks for any tips!

    1. You can follow the baking instructions for my three layer confetti cake here on the blog. It’s three 8-inch cake pans, same temp but shorter time.

    Hi! Do you have any gluten free cakes or have you experimented with swapping the cake flour for a 1-1 gluten free flour? Thanks!

    1. My chocolate cake is so good when I use cup for cup GF flour!

  4. Kenzie Petersen says:

    What’s the best substitute for vegetable oil in this recipe?

  5. Would this recipe work for cupcakes too? If so, any tips for baking temp and time?

    1. Yes! About 18-20 mins at 350 degrees.
