Easy Homemade Funfetti Cupcakes

Soft, fluffy homemade funfetti cupcakes that are worlds better than anything you will find in a box! They’re quite easy, too.

I recently developed a homemade funfetti cupcake recipe that may just be easier than your store-bought mix. So fluffy, so soft, spiked with vanilla, and bursting through the seams with colorful speckles.

I made a batch of homemade funfetti cupcakes for my birthday earlier this year and they were an instant hit. While my original homemade funfetti cupcakes are outstanding, I wanted a fluffier, whiter, and cakier cupcake that is still as simple as my original recipe. And, well, as simple as a boxed mix. I found a winner. Using easy everyday ingredients, this homemade recipe only takes about 25 minutes AND tastes 1,000% better than anything on the store shelves.

All-purpose flour, leavening agents (baking powder & soda), salt, white sugar, 1 stick of melted butter, vanilla extract, yogurt (or sour cream), and milk. Doesn’t that sound easy? The dry ingredients are tossed together by hand. Grab a wooden spoon or rubber spatula and mix together the melted butter and sugar.

The back of your funfetti box mix probably calls for oil and not butter. I love using oil in cake and cupcake recipes because it brings the finished baked good SO much moisture and a delicate texture. However, I decided to use butter in my recipe because the addition of plain yogurt (or sour cream) does a great job keeping things moist and soft. Plus, you still get a buttery taste.

To the sugar/butter mixture, you will add the egg, yogurt, vanilla, and milk. Whisk it all up by hand. Slowly stir in the dry ingredients. Use a bit of elbow grease and stir out all the lumps. The batter will be thick.

Be careful adding in your sprinkles. If you are using nonpareil sprinkles (the little balls), their colors will quickly bleed into your batter. I used nonpareil because they are my favorite. I had to be sure to gently mix them into the batter to avoid tie-dye cupcakes.

Which wouldn’t be so bad though, right?

Divide your batter evenly between 12 muffin liners and bake at 350F. You’ll know they are finished when a toothpick comes out clean.

I used a Wilton 12 frosting tip (a round tip) to frost the cupcakes. Frost the cooled cupcakes however you prefer – slathering on with a knife or piping on with a tip.

The cupcakes are so soft, moist, and fluffy with a buttery smooth taste. The frosting is fluffy, thick, and so easy to throw together. If you’d prefer a chocolate frosting, I suggest my chocolate buttercream. It’s smooth, rich, and extra creamy. I used a Wilton 1M swirl tip for the chocolate version:

Description

Soft, fluffy homemade funfetti cupcakes that are worlds better than anything you will find in a box!  They’re quite easy, too.


Ingredients

Cupcakes

  • 1 and 2/3 cups all-purpose flour (spoon & leveled)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 cup granulated sugar
  • 1 large egg
  • 1/4 cup yogurt*
  • 3/4 cup milk*
  • 2 teaspoons pure vanilla extract
  • 1/2 cup rainbow sprinkles (not nonpareils)

Vanilla Buttercream

  • 3/4 cup (170g) unsalted butter, softened to room temperature
  • 3 cups (360g) confectioners’ sugar
  • 1/4 cup (60ml) heavy cream or half-and-half*
  • 2 teaspoons pure vanilla extract
  • salt, to taste

Instructions

  1. Preheat oven to 350°F (177°C). Line muffin tin with 12 cupcake liners. Set aside.
  2. Make the cupcakes: In a medium bowl, mix together flour, baking powder, baking soda, and salt. Set aside. In a large microwave-safe bowl, melt butter in the microwave. Whisk in sugar – mixture will be gritty. Chill in the refrigerator for 1 minute. Stir in egg, yogurt, milk, and vanilla extract until combined. Slowly mix in dry ingredients until no lumps remain. Batter will be thick. Slowly stir in sprinkles, but do not overmix because the sprinkles will bleed their color.
  3. Divide batter among 12 cupcake liners and bake for up to 20 minutes or until a toothpick inserted in the center comes out clean. Allow to cool.
  4. Make the frosting: in a medium bowl, beat the softened butter on medium speed with an electric or stand mixer fitted with a paddle attachment. Beat for about 3 minutes until smooth and creamy. Turn mixer off and add confectioners’  sugar, cream, and vanilla extract. Mix on low for 1 minute then increase to high speed and beat for 3-4 full minutes. Add more powdered sugar if frosting is too thin or more cream if frosting is too thick. Add salt if frosting is too sweet (I usually add 1/4 teaspoon). Frost cooled cupcakes and top with sprinkles.
  5. Store cupcakes in an airtight container at room temperature for up to 3 days and in the refrigerator up to 5.

Notes

  1. Yogurt: You can use plain or vanilla regular/Greek yogurt or sour cream.
  2. Milk: You can use regular milk, soy milk, or almond milk.
  3. Frosting: Feel free to top with chocolate buttercream instead.
  4. Mini Cupcakes: For 24 mini cupcakes, bake 11-13 minutes or until a toothpick inserted in the center comes out clean.

  1. These turned out perfect for me. I made the mini versions because I wanted to have the smaller portions. I love the buttery flavor and I have to say, I prefer them to the egg white only version. I got more than 24 and needed 1.5 times the frosting quantity. This recipe is a keeper. Thanks, Sally, you really have the best baking recipes.

  2. What would the baking instructions be if I wanted to make this a 9×13 cake?

    1. Trina @ Sally's Baking Addiction says:

      Hi Georgia! We recommend following our recipe for white cake instead (follow the baking instructions for a 9×13 in the reicpe notes). It makes the perfect amount of batter. You can fold in 1/2 -2/3 cup of sprinkles (jimmies, not nonpareils) to that batter to make a funfetti cake. Enjoy!

  3. What would you sub for yogurt? We’re currently out as baby can’t have dairy.

    1. Stephanie @ Sally's Baking Addiction says:

      Hi Kristi, You can use sour cream instead of the yogurt.
