Easy Homemade Funfetti Cake with Vanilla Buttercream

I’ve always loved Funfetti. Who can resist all those sprinkles buried in soft, fluffy cake.

Aside from my seven year old daughter, there’s one person who loves sprinkles even more.

Her name is Jessica and she’s having a baby! I’m sure you ‘know’ Jessica, it’s pretty hard not to.

With her amazingly creative recipes that she’s been cranking out for 5+ years on her blog, her newly launched cookbook, and her witty and totally down-to-earth sense of humor and charm that makes you feel like you’re having a conversation with your best girlfriend, she’s a best friend to us all.

To celebrate, lots of friends and I are throwing her a virtual baby shower. We’re all making a dish in her honor and when thinking about what to make, I instantly knew it had to have tons of sprinkles.

Enter this Funfetti cake with sprinkles in the batter and a nice wall of sprinkles on the buttercream. Sprinkle overload, such a beautiful thing.

The recipe is as close to cake mix Funfetti 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.

It’s 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.

I wish I could have given Jessica a big fat piece of this cake, but my daughter’s eyes lit up when she saw it and she had no problem inhaling it.

She had a frosting mustache and sprinkles everywhere to prove it.

Easy Homemade Funfetti Cake with Vanilla Buttercream

The recipe is as close to cake mix Funfetti that I've been able to replicate at home. I love that stuff, but it's nice to be able to pronounce all the ingredients and make a scratch cake in literally 5 minutes. This easy, no mixer cake is adapted my favorite buttermilk cake base that I’ve used for so many cakes. 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. Between the sprinkles in the batter and a nice wall of sprinkles on the buttercream, you'll be in sprinkle overload, such a beautiful thing.

Yield: one 8x8 pan, 9 to 12 generous squares

Prep Time: 10 minutes

Cook Time: about 30 minutes

Total Time: about 90 minutes, for cooling

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. Wondering if this recipe could be doubled and baked in two 9 inch round pans to make a layer cake?

  2. This cake looks amazing!!! I’m baking for the office – wondering what your thoughts are re: making this recipe into cupcakes?

    • Haven’t tried making it as cupcakes but if you read over the comments, I’m pretty sure there have been a few who have tried. Since I haven’t tried, I can’t say for sure. Probably okay, but can’t vouch personally.

  3. I tried this recipe today and made it as cupcakes. They turned out great and are so delicious! I will never use the cake mix again. (The recipe made 12 cupcakes and I baked them at the same temperature for 20 minutes)

    • Thanks for trying the recipe and I’m glad it came out great for you! And glad you’ll never need cake mix again after this recipe! Great info that you got 12 cupcakes and baked for 20 mins!

  4. This looks incredible! I was wondering if I substituted the unsalted butter with salted butter in the icing if it would make a big difference?

  5. Can this recipe be used for cupcakes as well??

  6. Just made this–amazing! My husband and I love the funfetti cake made from a box but somehow this is even better! Thanks for the recipe!

  7. Hi Averie, just made the frosting and it turned out to be more tan / yellowish and far away from the white on your pictures… maybe the butter is different in Germany? :)

    • I have a feeling it is. When I buy European butter here in the US (expensive so I don’t do it often) but it’s noticeably more yellow. You could always put food coloring in the frosting to turn it pink or something or yellow for purposefully yellow, and that would solve the color issue.

  8. Really want to make this cake for my boyfriends birthday but I don’t own an 8×8 pan. Is there any other baking pan you would recommend? Thank you!

  9. Our daughter is planning a sleepover this weekend, we are so going to make this with the girls over here at our house! I will have to make minor variations to go dairy-free to accommodate allergies so fingers crossed it’s still fabulous!!

  10. This recipe is sooooo good! My husband loves the funfetti box mix but I hate using those store bought mixes and I came across this. I baked mine into mini cupcakes at the same temp for about 12-15 minutes. This is the second time this week I have made them. The buttercream is simple yet, DELICIOUS! Today I doubled the icing… to have a little left over for myself.
