Ingredients You’ll Need

2 cups granulated sugar: This creates a beautifully sweet balance while helping achieve a light fluffiness in the cake.
1/2 cup vegetable or canola oil: Adds moisture and keeps the cake tender. If desired, you can substitute with melted coconut oil.
4 large eggs (room temp): Binding the cake together, eggs also provide structure and moisture. Make sure they’re at room temperature for the best mixing.
1 tbsp vanilla extract: This provides depth of flavor and a warm aroma throughout the cake.
1/2 cup full-fat sour cream (room temp): Contributes to the moist texture. Greek yogurt can be used as a substitute.
2 1/2 tsp baking powder: This is your leavening agent, helping the cake rise perfectly.
1/2 tsp baking soda: Works alongside the baking powder for a soft, airy texture.
1 tsp kosher salt: Enhances the sweetness and balances flavors in the cake.
3 1/4 cups all-purpose flour (spooned and leveled): The foundation of your cake, it gives the structure. Avoid over-measuring to keep the cake light.
1 cup buttermilk (room temp): Adds tanginess and further moisture. If you’re out, just combine 1 cup of milk with 1 tbsp of vinegar.
3/4 cup rainbow jimmies sprinkles: The hallmark of funfetti! Make sure to use the nonpareil type for the best results.
1 1/2 cups unsalted butter (room temp, for frosting): For a rich and creamy buttercream, this ingredient is key.
5 cups powdered sugar (spooned and leveled): Provides sweetness and structure to the frosting; adjust based on your sweetness preference.
1 tbsp vanilla extract (for frosting): As with the cake, this adds a luscious flavor to the buttercream.
2-3 tbsp milk (room temp): This helps achieve the perfect buttery consistency for easy spreading.
1/2 cup sprinkles for decorating: Add a joyful touch to the finished cake.

How to Make Funfetti Cake

Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and line the bottoms of three 9-inch cake pans with parchment paper. If using 8-inch pans, make sure to fill them slightly under halfway to avoid overflow and sinking.
Beat Butter and Sugar: In a large mixing bowl, combine 1 cup unsalted butter and 2 cups granulated sugar. Using a hand or stand mixer with a paddle attachment, mix on medium-high speed until light and fluffy, about 3 minutes.
Add Oil and Eggs: With the mixer running on low, drizzle in 1/2 cup vegetable or canola oil. Scrape down the sides, then add eggs one at a time, mixing well after each addition. Lastly, mix in 1 tbsp vanilla extract and 1/2 cup room-temperature sour cream.
Mix Dry Ingredients: Add 2 1/2 tsp baking powder, 1/2 tsp baking soda, and 1 tsp kosher salt. Mix briefly, then gradually incorporate 3 1/4 cups all-purpose flour until halfway combined.
Add Buttermilk and Flour: Pour in the 1 cup buttermilk. Give it a rough mix, then add the remaining flour and mix until the batter is smooth.
Fold in Sprinkles: Gently fold in the 3/4 cup of rainbow jimmies sprinkles using a rubber spatula. Take care not to overmix; you want those sprinkles to remain intact.
Bake the Cakes: Divide the batter evenly among the prepared pans. Bake for 30-35 minutes (for 9-inch pans) or 35-40 minutes (for 8-inch pans)—check for doneness with a toothpick inserted into the center; it should come out clean.
Cool the Cakes: Let the cakes cool in the pans for about 30 minutes. Run a knife around the edges, then turn them out onto a cooling rack. Allow to cool completely before frosting.
Mix the Frosting: In a mixing bowl, beat 1 1/2 cups unsalted butter until smooth. Gradually add in the 5 cups powdered sugar and the 1 tbsp vanilla extract. If the frosting is too thick, mix in 2-3 tbsp of milk until achieving a smooth, spreadable consistency.
Crumb Coat the Cake: Spread a thin layer of buttercream between each layer of cake. For a clean finish, apply a thin “crumb coat” around the whole cake and refrigerate it for 20 minutes.
Final Frosting and Decoration: Frost the remaining buttercream over the entire cake and generously top it with the 1/2 cup of sprinkles.

Storing & Reheating
To store your funfetti cake, keep it covered at room temperature for up to 2 days. If you have leftovers, refrigerate it in an airtight container for up to a week. For longer storage, wrap tightly in plastic wrap and freeze for up to 3 months. When you’re ready to enjoy it again, simply let it sit at room temperature for about 30 minutes or warm it gently in the microwave for 10-15 seconds to bring back that fresh flavor.

Chef’s Helpful Tips

Avoid overmixing the batter once you add the flour; this will help keep your cake tender.
Ensure your butter and eggs are at room temperature—this promotes better mixing and a smoother batter.
If your cake domes in the center, trim the tops for an even layer. Use cake strips if you have them to help promote even baking!
Don’t fret if you have leftover frosting; it makes a fantastic dip for fresh fruit or cookies.
Experiment with different flavored extracts like almond or lemon for unique twists on the classic recipe.

While the funfetti cake is undeniably a delightful celebration of color and flavor, this recipe opens doors to creativity in your baking endeavors. The sheer joy of creating and sharing this cake with friends and family is what truly matters. Perhaps even consider adding layers of fruit filling or experimenting with different frosting styles to make it uniquely yours. No matter how you choose to decorate or serve it, the fun and love baked into each layer will shine through. Enjoy each vibrant bite!

Recipe FAQs

How do I prevent my cake from being dry?

Make sure to measure your flour correctly—too much flour can lead to a dry cake. Also, don’t bake it for too long; check for doneness a few minutes before the recommended time.

Can I use different sprinkles?

Absolutely! You can use nonpareils, confetti sprinkles, or any fun themed sprinkles you can find. Just ensure they are the kind meant for baking as some may bleed colors.

Can I make this cake ahead of time?

Yes, you can bake the cake layers ahead of time. Allow them to cool completely, wrap in plastic, and store in the refrigerator for up to a week or freeze for up to 3 months.

What’s the best way to frost the cake?

For a smooth frosting application, use an offset spatula. Start by applying a thin crumb coat to trap crumbs, chilling it for 20 minutes, then apply a final layer of frosting for a clean finish.
