Ingredients You’ll Need
Gathering the right ingredients is the first step toward baking your perfect Homemade Funfetti Cake Recipe. Each element plays a crucial role, from the soft cake flour that creates tenderness to the rainbow jimmies sprinkles that give this cake its signature fun and festive look.
- Unbleached cake flour: The base of the cake that creates a soft texture with a fine crumb, essential for that perfect cake feel.
- Granulated sugar: Adds sweetness while helping to create a delicate structure in the cake layers.
- Baking powder: The leavening agent responsible for the cake’s lovely rise and lightness.
- Vanilla powder: Enhances flavor with a pure, aromatic vanilla essence that complements the sprinkles beautifully.
- Fine sea salt: Balances sweetness and intensifies all the other flavors.
- Unsalted butter (cubed): Incorporated into the dry ingredients to add richness and a tender crumb.
- Large eggs: Act as a binder and provide moisture and structure—room temperature ensures smooth mixing.
- Whole milk: Moisturizes the batter and helps with the cake’s softness.
- Heavy cream: Adds richness and keeps the cake moist and tender.
- Sour cream: Provides tanginess and contributes to the cake’s tender texture.
- Vegetable oil: Makes the cake incredibly moist without weighing it down.
- Imitation vanilla (or real vanilla): Adds that classic box cake flavor — a nostalgic touch everyone loves.
- Rainbow jimmies sprinkles: The stars of the show that bring color and a festive crunch to every bite.
- Salted butter (for frosting): Gives the frosting richness and creaminess with a subtle salt contrast.
- Unsalted butter (for frosting): Keeps the frosting light and fluffy without overpowering saltiness.
- Powdered sugar: Sweetens and provides structure to the fluffy frosting.
- Heavy cream (for frosting): Makes the frosting rich, smooth, and spreadable for perfect coverage.
- Pure vanilla bean paste or extract: Infuses the frosting with that irresistible vanilla aroma and flavor.
How to Make Homemade Funfetti Cake Recipe
Step 1: Prepare Your Pans and Preheat the Oven
Start by preheating your oven to 325°F (160°C). Grease and flour three 8-inch cake pans, then line the bottoms with parchment paper to ensure your cake layers come out cleanly and beautifully. This simple preparation sets the foundation for perfectly shaped layers.
Step 2: Mix the Dry Ingredients and Butter
In a stand mixer bowl, whisk together the cake flour, granulated sugar, baking powder, vanilla powder, and sea salt. Then, on low speed, blend in the cubed butter until the mixture looks sandy and crumbly. This technique creates a tender crumb and helps the butter incorporate seamlessly.
Step 3: Combine the Wet Ingredients
In a separate bowl, whisk together your eggs, whole milk, heavy cream, sour cream, vegetable oil, and vanilla imitation. Having all wet ingredients at room temperature ensures even mixing and contributes to that moist cake texture you’ll love.
Step 4: Bring Dry and Wet Together with Sprinkles
Gradually add half of the wet ingredients to the dry mixture, mixing until just moistened. Scrape down the sides of the bowl, then add the remaining wet ingredients and fold in the rainbow jimmies sprinkles on low speed until just combined. The gentle mixing helps keep those sprinkles intact so they don’t bleed color into your batter.
Step 5: Bake the Cake Layers
Divide the batter evenly among your three pans—about 475 grams per pan. Bake for 25 to 30 minutes, until the edges turn golden brown and a toothpick inserted in the center comes out with a few moist crumbs. Cool the pans on a wire rack for 20-30 minutes before carefully removing the cakes and letting them cool completely.
Step 6: Make the Frosting
Using a stand or hand mixer, beat the butter on medium speed until it’s light and fluffy, roughly 2 to 3 minutes. Add powdered sugar slowly to prevent it from flying out, then increase the speed and beat for 4 to 5 minutes until the frosting is bright white and airy. Stir in the heavy cream and vanilla bean paste or extract, mixing until smooth.
Step 7: Assemble Your Funfetti Cake
Place the first cake layer on your serving platter. Spread an even layer of frosting on top, then stack the second cake layer and repeat. Place the final layer upside down for a flat top. Apply a thin crumb coat over the whole cake, chill it in the fridge for 20-30 minutes, then finish frosting with the remaining buttercream. For a festive touch, sprinkle extra rainbow jimmies on top and around the sides.
How to Serve Homemade Funfetti Cake Recipe
Garnishes
A sprinkle of extra rainbow jimmies or festive edible confetti instantly elevates your cake’s playful look. For added texture, consider tiny sugar pearls or a few fresh raspberries on top, and if you want a touch of elegance, edible gold leaf can add sparkle without hiding that fun color burst.
Side Dishes
Pair this vibrant cake with light, complementary sides like fresh berries or a dollop of whipped cream to keep the focus on the cake’s rich flavor. A simple fruit salad or a scoop of vanilla bean ice cream also works beautifully, balancing the sweetness while enhancing the celebration vibe.
Creative Ways to Present
Serve your Homemade Funfetti Cake Recipe on a colorful cake stand to highlight those joyful sprinkles. For parties, consider slicing it into mini cake cups or cupcakes for easy sharing. You can also craft a fun birthday message with contrasting colored icing or add themed toppers that match your event’s spirit.
Make Ahead and Storage
Storing Leftovers
Once your cake is fully frosted, store any leftovers in an airtight container at room temperature for up to two days. If your kitchen is warm, keeping it in the refrigerator is fine, but bring it back to room temperature before serving to restore its moist texture.
Freezing
You can freeze un-frosted cake layers tightly wrapped in plastic wrap and foil for up to three months. Thaw completely at room temperature before frosting. Alternatively, freeze the fully assembled and frosted cake in a cake container and consume within one month, thawing overnight in the fridge.
Reheating
Cake is best enjoyed fresh or at room temperature, so reheating isn’t usually necessary. If you prefer a warm slice, briefly microwave a single portion for about 10 seconds to enhance that soft, fresh-baked feeling without drying it out.
FAQs
Can I substitute real vanilla for imitation vanilla in this recipe?
Absolutely! Real vanilla adds a richer, more complex flavor, which many bakers prefer. The recipe suggests imitation vanilla for a classic box cake vibe, but swapping it with pure vanilla extract or vanilla bean paste will work wonderfully.
Why is sour cream used in the batter?
Sour cream keeps the cake incredibly moist and tender while adding a subtle tang that balances the sweetness and enriches the overall flavor. It really helps create that perfect soft crumb we all adore in funfetti cakes.
What type of sprinkles should I use?
Rainbow jimmies sprinkles are recommended because they hold their shape better during baking and don’t bleed color into the batter, preserving the cake’s beautiful confetti look. Avoid powdered or sugar-coated sprinkles since they can melt and dull the colors.
Can I make this cake gluten-free?
While this recipe uses cake flour for a tender crumb, you can try substituting a gluten-free cake flour blend. Be aware that texture might slightly differ, so experiment and adjust the liquid or leavening as needed for best results.
How far in advance can I make the cake?
This cake can be baked and frosted a day in advance and stored in the fridge. Bringing it to room temperature before serving will help you enjoy the cake’s full flavor and tender texture. The frosting holds up well overnight, making it a convenient make-ahead dessert.

Buttercream Frosting
- 1 cup salted butter (room temperature)
- 1 1/2 cups unsalted butter (room temperature)
- 4 cups powdered sugar

Instructions
- Prepare the Cake Pans: Preheat your oven to 325°F (160°C). Grease and flour the sides of three 8-inch cake pans and line the bottoms with parchment paper to prevent sticking. Set them aside.
- Mix Dry Ingredients: In a stand mixer bowl, whisk together the cake flour, granulated sugar, baking powder, vanilla powder, and fine sea salt until well combined.
- Cream Butter into Dry Mix: On low speed, incorporate the cubed unsalted butter into the dry ingredients until the mixture reaches a sandy texture, about 2 to 3 minutes. This helps distribute the fat evenly.
- Combine Wet Ingredients: In a separate bowl, whisk together eggs, whole milk, heavy cream, sour cream, vegetable oil, and imitation vanilla until smooth and homogeneous.
- Add Wet Ingredients to Dry: Add half of the wet mixture into the dry mixture and mix until all the flour is moistened. Scrape down the sides of the bowl to ensure even mixing.
- Finish Mixing Batter: Add the remaining wet ingredients plus the rainbow sprinkles on low speed and mix just until combined. Avoid overmixing to keep the batter light.
- Distribute Batter and Bake: Evenly divide the batter into the prepared pans (approximately 475 grams each). Bake for 25 to 30 minutes, or until the edges turn golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool Cakes: Allow the cakes to cool in the pans on wire racks for 20 to 30 minutes. Then remove from pans and let them cool completely on the racks.
- Prepare Frosting Butter: Using a stand mixer or hand mixer, beat the salted and unsalted butter together on medium speed for 2 to 3 minutes until the mixture is light and fluffy.
- Add Sugar to Frosting: Gradually add the powdered sugar, pulsing at first to avoid a sugar cloud, then mix at medium speed for 4 to 5 minutes until the frosting is light, white, and fluffy.
- Add Cream and Vanilla: Mix in the heavy cream and vanilla bean paste or extract until just combined, resulting in a smooth and creamy frosting.
- Assemble Cake Layers: Place the first cooled cake layer onto your serving platter or cake stand. Apply an even layer of frosting on top. Repeat with the second layer and then place the final layer upside down to keep the top flat.
- Crumb Coat and Chill: Spread a thin layer of frosting over the entire assembled cake to seal in crumbs and refrigerate for 20 to 30 minutes to set the crumb coat.
- Final Frosting and Decoration: Apply the remaining frosting evenly over the cake. Use any leftover frosting to decorate as desired and garnish with additional rainbow sprinkles for a festive finish.
- Serve and Enjoy: Slice the cake and enjoy the colorful, flavorful funfetti layers with creamy buttercream.
Notes
- Use unbleached cake flour for the lightest texture; if unavailable, you can make a substitute by replacing 2 tablespoons of all-purpose flour per cup with cornstarch.
- Room temperature ingredients help create a smoother batter and better rise.
- Imitation vanilla gives a classic box cake flavor, but real vanilla extract or bean paste will provide a more authentic taste.
- Be careful not to overmix once sprinkles are added to prevent streaking colors.
- Ensure the cake layers are completely cooled before frosting to prevent melting.
- The cake layers bake very flat, so trimming is usually unnecessary.
- For best results, refrigerate the frosted cake before the final decoration to achieve a smooth finish.
