Easy Homemade FUNFETTI®-Inspired Cake with Vanilla Buttercream

This Funfetti Cake recipe is as close to store-bought Funfetti Cake Mix that I’ve been able to replicate at home. I have no shame in admitting my love for that stuff, but it’s nice to be able to pronounce all the ingredients and make a scratch cake in literally 5 minutes!

Funfetti Cake for a Celebration

I’ve always loved Funfetti. Who can resist all those sprinkles buried in soft, fluffy cake? None of us in my house can.

This Funfetti Cake has sprinkles in the batter and also has a wall of sprinkles in the Funfetti Frosting. Sprinkle overload, such a beautiful thing.

How to Make Homemade Funfetti Cake

For this Funfetti Cake (sometimes called Confetti Cake) I use an easy, no mixer cake that’s adapted my favorite buttermilk cake base that I’ve used for so many cakes including Vanilla Cake with Vanilla Bean Browned Butter Glaze, Lemon Buttermilk Cake with Lemon GlazeBlueberry Muffin and Buttermilk Pancakes CakeCream Cheese-Swirled Cherry and Mixed Berries Cake, The Best Pineapple Upside-Down Cake, and Caramelized Banana Upside-Down Cake and many more.

I love the cake base because it’s fast and easy to make, and the cakes always turn out supremely moist, springy, and fluffy thanks to buttermilk, sour cream, and oil.

That trifecta of moisturizing and tenderizing ingredients makes it impossible to have a dry cake.

Do I Have To Make The Frosting From Scratch

If you’re in a time crunch you don’t necessarily need to make scratch frosting. You can cheat and use a tub of store bought frosting.

However, since you’re making a scratch cake, making scratch frosting is the way I would do things. It only takes a couple minutes to whip together.

Ingredients:

Cake

  • 1 cup all-purpose flour
  • 3/4 cup granulated sugar
  • 2 teaspoons baking powder
  • pinch salt, optional and to taste
  • 1 large egg
  • 1/2 cup buttermilk
  • 1/3 cup sour cream, lite is okay (plain Greek yogurt may be substituted)
  • 1/4 cup canola or vegetable oil
  • 2 teaspoons vanilla extract
  • 1/2 cup sprinkles, or to taste

Vanilla Buttercream Frosting

  • 1/2 cup unsalted butter, softened
  • 2 teaspoons vanilla extract
  • pinch salt, optional and to taste (helps offset the sweetness)
  • 1 1/2 to 2 cups confectioners’ sugar (I use 2 cups)
  • 1/3 cup sprinkles, or to taste

Directions:

  1. Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
  2. Cake – In a large bowl, whisk together flour, granulated sugar, baking powder, optional salt; set aside.
  3. In a separate small bowl, whisk together the egg, buttermilk, sour cream, oil, and vanilla.
  4. Add the wet mixture to the dry, mixing lightly with a spoon or folding with a spatula until just combined. Small lumps will be present, don’t overmix or try to stir them smooth.
  5. Gently stir in the sprinkles, taking care not to overmix or they could bleed.
  6. Turn batter out into prepared pan and bake for about 30 minutes (start checking at 25 minutes), or until center is set and not jiggly, and a toothpick inserted in the center comes out clean or with a few moist crumbs, but no batter.
  7. Place pan on a wire rack and allow cake to cool. While cake cools, make the frosting.
  8. Vanilla Buttercream Frosting – To a large bowl, add the butter, vanilla, optional salt, and slowly add the confectioners’ sugar while beating with a handheld electric mixer until smooth and fluffy, about 3 minutes.
  9. Turn frosting out onto cooled cake, smoothing it lightly with a spatula or offset knife.
  10. Evenly sprinkle the sprinkles before slicing and serving. Cake will keep airtight at room temperature for up to 5 days (I’m comfortable storing frosted cakes at room temp, if you’re not store in the fridge) or in the freezer for up to 6 months.

  1. It honestly doesn’t take much longer to make a cake from scratch…and it always tastes SO much better and is better for you! YUM :)

  2. I made this today and it is delicious! Super moist. My husband normally only likes cake with some form of chocolate, but he loved it to. Easy to make with my kids helping and they were so excited for their sprinkles cake. Thanks so much for the recipe!

  3. Can’t ever have too many sprinkles–fun for adults and kids alike and it sounds delicious! I love the little bit of texture they add too.

  4. My daughter wants a rainbow cake this year. Do you think this batter would hold dye well and look pretty with the jimmies if the batter was dyed bright colors? I’ve done one before that didn’t work as well because the crumb wasn’t dense enough so the airiness didn’t allow for the colors to look super bright. The reviews on the cake are fantastic and I thought the colored jimmies would be sufficient for “rainbow,” but I am apparently very wrong! It needs to be colored WITH sprinkles!

    • I honestly really can’t say. I would make a trial run of it and see how it goes based on your expectations. It’s a VERY easy, fast, and inexpensive cake to make. Good luck!

    • You probably already made the cake, but I would have doubled the recipe and took half the batter and put it in the pan then take a
      few different bowl fulls of the remaining batter and added a drop or two of food coloring into each bowl. Then take those bowls of batter and drop it into several places on the batter that’s already in the pan. Swirl batter with a toothpick.

  5. Thanks for all the delicious looking recipes to choose from Averie! I just wanted to say you are a very gifted photographer, your photos are so beautiful and classy.

  6. hey girl- this cake looks so yummy!

  7. Could this be doubled and baked in a 9×13 pan?

  8. Could this be made into cupcakes?

  9. Could I make a cream cheese frosting for this? Any recommends for one that would work for this cakeV

  10. Can this recipe be used for a layered round cake? 8 or 9 inch if I doubled the recipe?

  11. Made this recipe into 12 delicious cupcakes! Baked for about 17 minutes. I used Ermine frosting, tinted pink, and they were amazing!! The reason I selected this was for the buttermilk/oil/sour cream mixture. It helps keep them so moist vs butter which seems to dry them out when refrigerated. Soooo easy to mix by hand. This is a keeper! *****

    • Thanks for the five star review and glad you love the cake! I completely agree about oil based cakes versus butter-based cakes. Oil just keeps things so much softer. It is 100% fat. Whereas butter is about 80% fat.

  12. I made this today and love it! Super easy and quick, but so much better than a box cake. So moist, and a richer flavor than a box cake. Icing was a breeze, too. If you make the icing, you can control the sweetness; I put in less powdered sugar (about a cup and a half) and liked the final outcome. Thanks for a keeper recipe.

  13. Oh my word Averie, you are my hero! I have searched and searched for a delicious, moist white cake for too many years (more than 25 years I’m guessing). I just made this for a second time within the week. This time I made two 8 inch round layers for a birthday cake for a coworker – who doesn’t love funfetti. I can not thank you enough for this recipe.

  14. Kathy Taber, did you double the recipe to make a 2-layer cake in 8 inch rounds??

  15. Would you change anything in the recipe if you wanted to make cupcakes with it? (Other than shorter baking time of course…)

  16. Hey! This looks delicious! Would you say itll make about 12 cupcakes?

  17. It was my daughter’s 21st and as always she asked me to bake a cake…. such a stressful job, right?
    I thought of adding sprinklers but was concerned if they bleed 🤔. I thought of you Averie and then jumped to your site.
    As always no fail recipe. Thank you, it’s a keep 👍🏻

  18. Hello! How do you think this would this hold up under fondant?
