What You’ll Need

To make the perfect Funfetti Birthday Cake, it’s essential to start with the right ingredients and tools. This recipe uses pantry staples and a few special additions—most notably, the sprinkles—that come together to create the classic, celebration-ready cake we all love. Whether you’re baking this for a birthday party, a graduation, or just to brighten a regular Tuesday, everything you need is listed right here.

Ingredients for the Funfetti Cake Layers:

2½ cups (315g) all-purpose flour – sifted for a light crumb
2½ teaspoons baking powder – provides that beautiful lift and fluffiness
½ teaspoon baking soda
½ teaspoon salt
¾ cup (170g) unsalted butter, softened – for richness and moisture
1¾ cups (350g) granulated sugar – sweetens and helps with texture
4 large egg whites, room temperature – keeps the cake white and fluffy
1 tablespoon vanilla extract – key for that classic birthday cake flavor
1 cup (240ml) buttermilk, room temperature – makes the cake extra tender
⅔ cup (110g) rainbow sprinkles – jimmies work best, as they bleed less into the batter

Ingredients for the Vanilla Buttercream Frosting:

1 cup (226g) unsalted butter, softened
4 cups (480g) powdered sugar
2–3 tablespoons milk – adjust for consistency
1 tablespoon vanilla extract
Pinch of salt
Extra rainbow sprinkles for decorating the outside

The magic of the Funfetti Birthday Cake is in the rainbow sprinkles, so it’s important to choose the right kind. Stick with the classic “jimmies”—the oblong-shaped sprinkles. Nonpareils (the tiny round balls) tend to bleed color into the batter and may affect the final look of the Funfetti Birthday Cake.

How to Make Funfetti Birthday Cake (Include Full Measurements)

Making a Funfetti Birthday Cake from scratch is surprisingly simple, and the result is a tender, moist vanilla cake bursting with colorful sprinkles that bring a festive flair to every slice. Follow these step-by-step instructions carefully to ensure your cake turns out perfectly.

Preparing the Cake Layers

Preheat your oven to 350°F (175°C). Grease three 8-inch round cake pans and line the bottoms with parchment paper rounds to prevent sticking.
Combine dry ingredients. In a medium bowl, whisk together 2½ cups of sifted all-purpose flour, 2½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Set aside.
Cream the butter and sugar. Using an electric mixer, beat ¾ cup softened unsalted butter with 1¾ cups granulated sugar on medium-high speed until the mixture is light, fluffy, and pale—about 4 to 5 minutes. This aeration is key to a light crumb in your Funfetti Birthday Cake.
Add egg whites and vanilla. Add 4 large egg whites one at a time, beating well after each addition. Mix in 1 tablespoon vanilla extract for that classic birthday cake flavor.
Alternate adding dry ingredients and buttermilk. Reduce mixer speed to low. Gradually add the dry flour mixture in three additions, alternating with 1 cup of room temperature buttermilk in two additions, beginning and ending with the flour. Mix each addition just until incorporated; do not overmix.
Fold in the sprinkles. Gently fold ⅔ cup rainbow sprinkles into the batter with a rubber spatula. Folding carefully prevents sprinkles from breaking or bleeding color, maintaining the cake’s vibrant funfetti appearance.
Divide and bake. Evenly distribute the batter among the prepared pans, smoothing the tops. Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Baking times may vary depending on your oven, so start checking at 25 minutes.
Cool completely. Remove the pans from the oven and let cool on wire racks for 10 minutes. Then invert cakes onto racks and remove parchment paper. Allow the layers to cool completely before frosting.

Making the Vanilla Buttercream Frosting

Beat the butter. In a large bowl, beat 1 cup softened unsalted butter on medium speed until creamy and smooth, about 2 minutes.
Add powdered sugar gradually. Reduce mixer speed to low and gradually add 4 cups powdered sugar, about 1 cup at a time, beating well after each addition.
Add vanilla, salt, and milk. Mix in 1 tablespoon vanilla extract and a pinch of salt. Add 2 to 3 tablespoons milk until the frosting reaches a spreadable consistency. Beat on high for 3 to 4 minutes until light and fluffy.
Assemble your Funfetti Birthday Cake. Level cake layers if necessary, then spread a thick layer of frosting between each. Finish by frosting the top and sides of the cake. Decorate with extra sprinkles around the edges or top for that iconic festive look.

Following this method ensures your Funfetti Birthday Cake comes out moist, colorful, and perfectly sweet—just like the celebratory cake everyone loves.

Serving and Storage Tips for Funfetti Birthday Cake

Serving and storing your Funfetti Birthday Cake properly will help maintain its freshness, texture, and vibrant appearance, ensuring everyone enjoys this special treat at its best.

Serving Tips

Bring to room temperature. Before serving, remove the Funfetti Birthday Cake from the fridge about 30 minutes ahead of time. This allows the buttercream frosting to soften and the cake layers to become tender and flavorful.
Cut clean slices. Use a sharp serrated knife warmed under hot water, then wiped dry, for smooth, clean cuts. This helps preserve the neat appearance of your layers and prevents crumbs from scattering.
Pairing suggestions. The Funfetti Birthday Cake pairs wonderfully with classic drinks like cold milk or vanilla ice cream. For a party, consider offering fruit punch or lemonade for a refreshing contrast to the sweet cake.

Storage Tips

Short-term storage: Keep your frosted Funfetti Birthday Cake covered loosely with a cake dome or an overturned large bowl at room temperature if you plan to eat it within 1 to 2 days.
Longer storage: For storage beyond 2 days, place the cake in an airtight container and refrigerate. The cake will stay fresh in the fridge for up to 5 days. Let it come back to room temperature before serving to regain the perfect texture.
Freezing: If you want to freeze the Funfetti Birthday Cake, it’s best to freeze the unfrosted layers. Wrap each cooled layer tightly in plastic wrap and then in foil. Freeze for up to 2 months. Thaw in the refrigerator overnight before frosting and assembling.
Avoid moisture: To prevent the sprinkles from bleeding colors, avoid excessive moisture or humidity. Store the cake in a cool, dry place.

By following these serving and storage tips, your Funfetti Birthday Cake will look just as cheerful and taste just as delicious whether you’re enjoying it fresh from the oven or savoring leftovers days later.

Mistakes to Avoid When Making Funfetti Birthday Cake

Baking a perfect Funfetti Birthday Cake can seem simple, but there are common pitfalls that can impact the texture, appearance, and flavor. Avoiding these mistakes will help you create a cake that’s not only festive and colorful but also moist, tender, and delicious every time.

1. Using the Wrong Type of Sprinkles

One of the biggest mistakes when making a Funfetti Birthday Cake is using nonpareil sprinkles instead of jimmies. Nonpareils are tiny round beads that tend to bleed their color into the batter during baking, turning your vibrant confetti into a muddy swirl. For the best look, use rainbow jimmies — the longer, cylindrical sprinkles — which hold their shape and color much better when baked.

2. Overmixing the Batter

Overmixing is a classic baking error that can affect the crumb and rise of your Funfetti Birthday Cake. When you mix the flour and wet ingredients too vigorously or for too long, the gluten develops excessively, resulting in a dense, tough cake instead of a soft, fluffy one. Mix only until the ingredients are just combined, especially after adding the flour.

3. Not Sifting the Dry Ingredients

Skipping the step of sifting flour, baking powder, and baking soda can lead to clumps in your batter, causing uneven texture and pockets of baking powder that leave unpleasant tastes. Sifting also aerates the dry ingredients, helping the cake layers to be lighter and fluffier, essential for the perfect Funfetti Birthday Cake.

4. Incorrect Oven Temperature

Baking at the wrong temperature is another common cause of disappointing cakes. Too hot, and the cake will brown too quickly on the outside but remain raw inside. Too low, and the cake may not rise properly or develop a dense texture. Always preheat your oven and use an oven thermometer if possible to ensure the correct 350°F (175°C) for your Funfetti Birthday Cake.

5. Frosting the Cake While the Layers Are Warm

Applying frosting to warm cake layers causes the buttercream to melt and slide off, resulting in a messy and unappealing finish. Always wait until your Funfetti Birthday Cake layers are completely cool before frosting. This step is critical to achieve a smooth, stable finish and maintain the cake’s colorful, festive look.

6. Using Cold Ingredients

Cold butter or eggs can prevent your batter from emulsifying properly, leading to a lumpy texture or dense crumb. For the best Funfetti Birthday Cake, use room temperature ingredients to ensure they blend smoothly and help the cake rise evenly.

Avoiding these mistakes will set you up for baking success, ensuring your Funfetti Birthday Cake turns out exactly as joyful and delicious as you expect.

Tips and Tricks for the Perfect Funfetti Birthday Cake

Want to make your Funfetti Birthday Cake stand out and taste even better? These expert tips and tricks will help you elevate your baking game and create a cake that’s not just festive but also flawlessly textured and flavorful.

1. Use High-Quality Vanilla Extract

The vanilla flavor is the backbone of your Funfetti Birthday Cake. Opt for pure vanilla extract rather than imitation vanilla for a richer, more authentic flavor. This simple swap can make a noticeable difference in the taste.

2. Choose Buttermilk for Tenderness

Using buttermilk instead of regular milk adds a subtle tang and tender crumb to your cake layers. The acidity in buttermilk reacts with baking soda and baking powder, helping the cake rise and stay moist, which is perfect for a soft, fluffy Funfetti Birthday Cake.

3. Prevent Sprinkles from Bleeding

To keep your sprinkles vibrant and colorful inside the cake, fold them in gently at the very end of mixing. Avoid overmixing after adding sprinkles to prevent the colors from bleeding into the batter.

4. Level Your Cake Layers

For a professional look, level your cake layers with a serrated knife or cake leveler before frosting. Even layers help your Funfetti Birthday Cake stack neatly, giving it a polished and symmetrical appearance.

5. Chill the Cake Before Frosting

If your kitchen is warm, chilling your cake layers briefly before frosting helps the frosting stick better and prevents melting. This is especially helpful to keep your Funfetti Birthday Cake looking fresh and colorful.

6. Use a Cake Turntable

If you’re decorating your Funfetti Birthday Cake for a party, a cake turntable can make frosting and decorating easier and faster. It allows for smooth, even layers of frosting and neat edges.

7. Customize Sprinkles for Themed Parties

You can customize your Funfetti Birthday Cake by choosing sprinkles that match your party’s color scheme or theme. From pastel shades for baby showers to neon colors for summer parties, the options are endless.

8. Store Leftovers Properly

Cover your Funfetti Birthday Cake tightly with plastic wrap or a cake dome to keep it fresh. If refrigerated, bring it to room temperature before serving for the best texture and flavor.

With these tried-and-true tips, your Funfetti Birthday Cake will always be a showstopper—delightful to the eyes and irresistible to the taste buds.
