Ingredients You'll Need

All you need is a handful of simple ingredients that each play an important role in making this cake a showstopper. From the fluffy whipped egg whites to the creamy butter in the frosting, every component contributes to the perfect texture, taste, and vibrant appearance.

• All-purpose flour (3¾ cups): The base that gives the cake its light and tender crumb.
• Baking powder (2½ teaspoons): Helps the cake rise beautifully and stay fluffy.
• Salt (1 teaspoon): Balances the sweetness and enhances flavor.
• Granulated sugar (2⅓ cups): Adds the perfect sweetness and tenderness.
• Unsalted butter, softened (1 cup + 1 pound for frosting): Provides rich flavor and smooth texture.
• Vegetable oil (⅓ cup): Keeps the cake moist without overpowering the flavor.
• Vanilla extract (1 tablespoon + 1 tablespoon for frosting): Adds warm, aromatic notes.
• Buttermilk (1⅓ cups): Adds tang and helps keep the cake tender and moist.
• Large egg whites (7, room temperature): Whipped to create an airy, light crumb.
• Rainbow jimmies (⅔ cup): The iconic colorful sprinkles that make this cake so fun and festive.
• Powdered sugar (2 pounds for frosting): Ensures the frosting is silky smooth and sweet.
• Heavy cream (3 to 4 tablespoons): Used to thin the frosting for a luscious, spreadable consistency.

Directions

Step 1: Preheat your oven to 350°F. Prepare three 8-inch round cake pans by lightly greasing them with butter or baking spray, then flouring the pans. Line the bottoms with parchment paper to make removing the cakes easier. If you have cake strips, I highly recommend using them to ensure even layers.

Step 2: Sift together the all-purpose flour, baking powder, and salt in a large bowl. Set this dry mixture aside for now.

Step 3: In a separate large mixing bowl, beat the granulated sugar, softened butter, and vegetable oil on medium speed until the mixture is silky smooth and creamy. This usually takes about three minutes, and it’s key for creating a light cake texture.

Step 4: Gradually add the egg whites to the butter mixture in three parts, mixing on low speed each time until fully incorporated. Be sure to scrape down the sides of your bowl occasionally. After the eggs are combined, add the vanilla and beat on medium speed for about 20 seconds until fluffy.

Step 5: Alternate adding the sifted flour mixture and buttermilk to the wet ingredients, beginning and ending with the flour mixture. Add one-third of the flour mixture, mix until just combined, then half of the buttermilk, and so on. Make sure to scrape the bowl and mix until you have a smooth batter with no lumps.

Step 6: Gently fold in the rainbow jimmies with a silicone spatula, being careful not to overmix so the sprinkles don’t bleed color into the batter.

Step 7: Divide the batter evenly between the prepared pans, smoothing the tops with an offset spatula. Tap each pan on the counter a few times to release any big air bubbles.

Step 8: Bake the cakes for 32 to 38 minutes, rotating the pans around halfway through baking to ensure even cooking. The cake is done when the centers spring back lightly to the touch.

Step 9: Let the cakes cool in their pans for 10 minutes before carefully turning them out onto wire racks. Remove the parchment paper once cool enough to handle.

Step 10: To make the frosting, beat the butter and salt on medium speed until soft and smooth, about two minutes.

Step 11: Slowly add the powdered sugar to the butter, mixing on low speed. Add the heavy cream one tablespoon at a time as needed to achieve a creamy consistency. Stir in the vanilla, then beat on medium speed for one to two minutes until fluffy.

Step 12: Assemble your cake by placing one cooled layer on a cake stand or plate. Spread about one cup of frosting evenly over the top. Repeat with the second and third layers.

Step 13: Use a piping bag fitted with a large open star tip to pipe decorative dollops of frosting around the top edge.

Step 14: Spread the remaining frosting evenly around the sides and top of the cake. Press rainbow sprinkles around the bottom edges, covering about two to three inches up the sides like a festive skirt.

Step 15: Add extra sprinkles on top if you’d like, and enjoy your beautiful, homemade Funfetti Cake!

Servings and Timing

This Funfetti Cake Recipe generously serves 12 people, making it perfect for a gathering or celebration. Preparing the batter and frosting takes about 40 to 50 minutes, with baking time around 35 minutes. Total active time including assembly comes to roughly 1 hour 30 minutes, but you’ll want to allow about 30 minutes extra for the cakes to cool completely before frosting and decorating. Altogether, you’re looking at about 2 hours from start to finish to enjoy this festive treat.

How to Serve This Funfetti Cake Recipe

When it comes to serving this Funfetti Cake Recipe, I love presenting it as the star of the dessert table with minimal accompaniment to highlight the cake’s joyful colors and flavors. It pairs beautifully with a scoop of vanilla ice cream or a light whipped cream to complement its buttery sweetness without overwhelming it.

For a pop of extra elegance, I like to garnish the cake platter with fresh berries or edible flowers around the edges. The rainbow sprinkles pressed along the sides give it an instant party vibe, but you can elevate it further by piping extra dollops of frosting around the plate or setting out a bowl of additional sprinkles so guests can customize their slices.

This cake is fantastic served at room temperature to enjoy the full flavor and tender crumb. For drinks, try pairing it with a chilled glass of sparkling rosé or a fruity punch to match the fun, festive spirit. If you prefer non-alcoholic options, a bright lemonade or a creamy vanilla milkshake works wonderfully. I find this cake especially perfect for birthdays, holiday celebrations, and casual weekend get-togethers where everyone feels invited to smile and relax.

Variations

I’ve experimented with several variations of this Funfetti Cake Recipe depending on the occasion and dietary needs. For a gluten-free version, swapping the all-purpose flour for a finely milled gluten-free blend works well, though I usually add an extra teaspoon of baking powder to maintain fluffiness. For vegan adaptations, I replace the egg whites with aquafaba whipped to stiff peaks, and use dairy-free butter and plant-based milk to keep things moist and flavorful.

If you’re craving different flavors, I love adding a splash of almond extract along with the vanilla or stirring in some citrus zest like lemon or orange to the batter for a bright twist. You could also mix in chocolate chips instead of sprinkles for a fun but different take. For cooking methods, while I always prefer baking in round pans for layering, you could try using a bundt pan for a different shape or even cupcakes to make individual servings that keep the funfetti spirit.

Storage and Reheating

Storing Leftovers

After enjoying your funfetti cake, I recommend storing leftovers by placing the cake in an airtight container or wrapping it tightly with plastic wrap to lock in freshness. Keep it refrigerated for up to 4 to 5 days. If your kitchen is warm, refrigeration is best to prevent the frosting from becoming too soft, but be sure to allow the cake to come to room temperature before serving for the best flavor.

Freezing

This cake freezes well if you want to save some for later. I usually wrap each cake layer tightly in plastic wrap first, then place them in a freezer-safe bag or container. The assembled, frosted cake can also be frozen if well wrapped. Frozen cake layers or the whole cake will keep for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight, then bring to room temperature before serving.

Reheating

I generally don’t recommend reheating this cake in the microwave, as it can alter the texture of the frosting and cake crumb. Instead, allow slices to come to room temperature naturally after refrigeration. If you want a warm dessert, serving a small piece with a warm sauce like chocolate or caramel drizzle, or alongside warm fruit compote, is a delicious way to enjoy the cake warmed without changing its texture.

FAQs

Can I use regular whole eggs instead of egg whites?

While whole eggs can be used in some cake recipes, this Funfetti Cake Recipe relies on whipped egg whites to create its signature light and airy texture. Using whole eggs will result in a denser cake, so I recommend sticking to just the egg whites as instructed.

What can I substitute for buttermilk if I don’t have any?

If you don’t have buttermilk on hand, you can easily make a substitute by adding one tablespoon of lemon juice or white vinegar to one cup of milk. Let it sit for about 5 minutes until it curdles slightly, and then use it as you would buttermilk in the recipe.

How do I prevent the sprinkles from bleeding colors into the batter?

To keep the sprinkles from bleeding, fold them gently into the batter at the very end of mixing. Using rainbow jimmies instead of regular nonpareils helps, as jimmies tend to hold their color better. Also, avoid overmixing once the sprinkles are added.

Can I make this cake in advance?

Absolutely! You can bake the cake layers a day or two ahead and keep them wrapped tightly in the refrigerator. The frosting can also be made in advance and stored in the fridge. Just assemble the cake the day you plan to serve it for the freshest look and taste.

Is this recipe suitable for kids’ parties?

Definitely. This Funfetti Cake Recipe is a classic celebration cake that kids adore thanks to the colorful sprinkles and sweet frosting. It’s bright, festive, and not too complicated, making it a great baking project to do with kids or serve at parties where fun and flavor are the focus.
