Why Everyone Loves Funfetti Cake
There’s something magical about cutting into a cake and seeing bursts of rainbow sprinkles throughout. Funfetti cake isn’t just dessert—it’s a mood booster, a conversation starter, and a guaranteed crowd-pleaser. Whether you’re celebrating a birthday, hosting a baby shower, or just need a little extra joy in your day, this funfetti cake recipe delivers on all fronts.
Unlike store-bought versions that can be dry or overly sweet, this homemade funfetti cake is soft, moist, and perfectly balanced in flavor. The secret? A blend of oil for moisture, buttermilk for tenderness, and real vanilla extract for that classic vanilla cake taste. Plus, folding in rainbow jimmies (not nonpareils—more on that later!) ensures every bite is a surprise party in your mouth.
What Makes This Funfetti Cake Recipe Special
This isn’t just another vanilla cake with sprinkles stirred in. This recipe is carefully crafted to give you the best texture, flavor, and visual appeal. We’re talking about a cake that’s light as air, stays moist for days, and has just the right amount of sweetness—not too much, not too little.
One of the biggest mistakes people make with funfetti cake is using the wrong kind of sprinkles. Nonpareils (the tiny round ones) can bleed into the batter and turn your cake gray or streaky. That’s why this recipe calls for jimmies—the longer, cylindrical sprinkles that hold their color and shape during baking. You’ll find them in most grocery stores near the baking supplies.
Another standout feature? This cake is actually easy. No stand mixer required (though you can use one), no complicated steps, and no hard-to-find ingredients. It’s perfect for beginner bakers and busy parents alike. And if you’ve ever tried our vanilla cupcake recipe, you’ll love how similar this funfetti version is—just with a festive twist.
Ingredients You’ll Need

Dry Ingredients

- 2 teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
Wet Ingredients
- ¾ cup (180ml) whole milk or buttermilk (buttermilk preferred for tenderness)
- 1 teaspoon pure vanilla extract
- 1 cup (200g) granulated sugar
- ½ cup (120ml) vegetable oil or canola oil
- 2 large eggs, at room temperature

- ½ cup (about 100g) rainbow jimmies (not nonpareils!)
- 1 batch of vanilla buttercream frosting (recipe below)

Step-by-Step Instructions
Ready to bake? This funfetti cake recipe comes together in under an hour, including prep and baking time. Let’s get started!
Preheat & Prep
Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper. This ensures easy removal and a clean finish.
Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
Cream Wet Ingredients
In a large mixing bowl, whisk the sugar and oil until well combined. Add the eggs one at a time, mixing well after each. Stir in the vanilla and buttermilk until smooth.
Combine & Fold in Sprinkles
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Don’t overmix—this keeps the cake tender. Gently fold in the rainbow jimmies using a spatula. Be careful not to over-stir, or the sprinkles may break or bleed.
Bake
Divide the batter evenly between the prepared pans. Smooth the tops with a spatula. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
Cool & Frost
Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely before frosting. Once cooled, frost with vanilla buttercream and decorate with extra sprinkles.
Pro tip: For extra fluffiness, let your eggs and buttermilk come to room temperature before mixing. Cold ingredients can cause the batter to curdle slightly.
Vanilla Buttercream Frosting Recipe
No funfetti cake is complete without a fluffy, sweet, and creamy frosting. This vanilla buttercream is simple, stable, and pairs perfectly with the cake’s light texture.
Ingredients
- 1 cup (226g) unsalted butter, softened
- 4 cups (480g) powdered sugar, sifted
- 2–3 tablespoons heavy cream or milk
- 2 teaspoons pure vanilla extract
- Pinch of salt
Instructions
In a large bowl, beat the butter until creamy. Gradually add the powdered sugar, one cup at a time, mixing on low speed. Add vanilla, salt, and 2 tablespoons of cream. Increase speed and beat for 2–3 minutes until light and fluffy. Add more cream if needed to reach your desired consistency.
This frosting holds up well at room temperature and pipes beautifully if you want to get fancy with decorations. For a fun twist, try our chantilly cake style whipped cream frosting instead—it’s lighter and less sweet.
Serving, Storing & Making Ahead
This funfetti cake is best served at room temperature. Slice and enjoy with a glass of milk, a cup of coffee, or as the centerpiece of your party table.
Storage Tips
- Room temperature: Store covered for up to 3 days.
- Refrigerator: Keeps well for up to 5 days. Let it come to room temperature before serving for the best texture.
- Freezer: Wrap unfrosted cake layers in plastic wrap and freeze for up to 3 months. Thaw overnight in the fridge before frosting.
Make-Ahead Options
Bake the cake layers a day ahead and store them covered at room temperature. Frost on the day of serving for the freshest look and taste. You can also prepare the frosting up to 3 days in advance and keep it refrigerated—just re-whip before using.
If you’re planning a big event, consider making funfetti cake pops using leftover crumbs and frosting. They’re adorable, portable, and always a hit with guests.
Funfetti Cake Variations & Creative Ideas
Once you’ve mastered the classic version, feel free to get creative! Here are a few fun twists:

Layered Funfetti Dessert Cups
Crumbled cake + frosting + sprinkles in a clear cup = instant party dessert. Great for kids’ parties or outdoor events.

And if you’re feeling adventurous, try pairing this cake with other flavors. A thin layer of lemon curd between the cakes adds a bright contrast, or swirl in some strawberry puree for a fruity twist. Just like our strawberry cheesecake cake, combining flavors can take your dessert to the next level.

Frequently Asked Questions
Can I use boxed cake mix instead of making it from scratch?
Absolutely! You can doctor up a white or vanilla boxed mix by adding extra vanilla, substituting oil for butter, and folding in sprinkles. However, this homemade version is just as easy and tastes significantly fresher and more tender.
Why did my sprinkles bleed into the batter?
This usually happens when using nonpareils (tiny round sprinkles) instead of jimmies. Nonpareils contain water-soluble dyes that run during baking. Always use jimmies for vibrant, streak-free results.
Can I make this cake gluten-free?
Yes! Substitute the all-purpose flour with a 1:1 gluten-free baking blend. Make sure your sprinkles are also certified gluten-free, as some brands use wheat-based ingredients.
How do I prevent my cake from being dense?
Avoid overmixing the batter—mix just until ingredients are combined. Also, ensure your baking powder and baking soda are fresh, and don’t skip the room-temperature eggs and buttermilk.
Can I freeze the frosted cake?
It’s best to freeze unfrosted layers. Frosting can become icy or separate when frozen and thawed. Wrap the frosted cake tightly in plastic and foil if you must freeze it, but consume within 1 month for best quality.
What’s the difference between funfetti and confetti cake?
They’re the same thing! “Funfetti” is a trademarked brand name (by Pillsbury), but the term has become generic for any vanilla cake with colorful sprinkles. So yes—your homemade version totally counts as funfetti!
