- 1 tsp salt: Balances sweetness and enhances overall flavor.

How to Make Funfetti Cake Recipe
Step 1: Prep Your Pans and Oven
First things first, preheat your oven to 350°F (175°C). Grease three 9-inch cake pans and line them with parchment paper. This ensures your cakes come out cleanly without sticking, providing a smooth surface for decorating later.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This mix is your cake’s backbone—it evenly distributes the leavening agents, so your layers rise uniformly and have a perfect crumb.
Step 3: Cream Butter and Sugar, Add Wet Ingredients
Using a mixer, cream the butter and granulated sugar until the mixture becomes light and fluffy—a crucial step that creates air pockets for that melt-in-your-mouth texture. Then mix in the oil to lock in moisture. Beat in eggs one at a time to maintain the light texture, and finish with vanilla extract to bring out a lovely aroma.
Step 4: Combine Sour Cream, Dry Ingredients, and Buttermilk
Stir in the sour cream gently, which adds richness and tenderness. Now alternate adding the dry mixture and buttermilk to the batter, starting and ending with the dry ingredients, and mix just until combined. This careful folding keeps your batter airy. Finally, fold in the 3/4 cup of rainbow jimmies sprinkles—the heart of any Funfetti Cake Recipe—without over-mixing, so they remain colorful and intact during baking.
Step 5: Bake to Perfection
Divide the batter evenly among the three pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Once baked, transfer the cakes to wire racks and allow them to cool completely before frosting. Cooling is key to prevent the buttercream from melting.
Step 6: Whip Up the Buttercream Frosting
Beat the frosting butter until smooth and creamy. Gradually add powdered sugar, vanilla, and milk, beating until fluffy and spreadable. This luscious frosting perfectly balances the sweet, buttery cake layers and adds that silky finishing touch.
Step 7: Assemble and Decorate
Spread buttercream evenly between layers and coat the outside of the cake. Then generously decorate with additional sprinkles for that signature festive look. This final step brings the Funfetti Cake Recipe to life, turning it into a centerpiece of any celebration.
How to Serve Funfetti Cake Recipe

Garnishes
Sprinkles are the obvious hero here, but you can also add a dusting of edible glitter or a few fresh berries on top. These simple garnishes elevate the cake’s festive spirit and create an irresistible visual appeal.
Side Dishes
Serve slices alongside a scoop of vanilla ice cream or a dollop of whipped cream to add creamy contrast. Fresh fruit, like strawberries or raspberries, can also brighten the palate and enhance the overall tasting experience.
Creative Ways to Present
For a unique twist, transform this Funfetti Cake Recipe into colorful cupcakes for individual servings, or make a fun layer cake with alternating colors of sprinkles for a surprise pop. You can even turn leftover cake into cake pops, dipped in chocolate and covered in sprinkles for a playful treat.
Make Ahead and Storage
Storing Leftovers
After enjoying your Funfetti Cake, wrap leftovers tightly with plastic wrap or store them in an airtight container at room temperature for up to two days to preserve moistness. For longer keeping, refrigeration is okay but bring the cake to room temperature before serving for the best flavor.
Freezing
This Funfetti Cake Recipe freezes beautifully. Wrap each cake layer tightly in plastic wrap and then foil, or freeze the fully assembled cake in an airtight container. When you’re ready to indulge, thaw in the refrigerator overnight for the most tender texture, then bring to room temperature.
Reheating
Since cakes are best enjoyed fresh or chilled, reheating is not typically necessary. If you prefer warm slices, briefly microwave individual portions for about 10 seconds, just enough to take the chill off without melting the buttercream completely.
FAQs
Can I substitute sour cream in this Funfetti Cake Recipe?
Yes, Greek yogurt can be used as a substitute for sour cream in equal amounts. It will maintain the moisture and tanginess, keeping the cake tender and flavorful.
Why are rainbow jimmies best for this recipe?
Rainbow jimmies hold their color well during baking and add vibrant splashes throughout the batter without melting into the cake, preserving that fun confetti effect that defines the Funfetti Cake Recipe.
Can I make this cake gluten-free?
You can try substituting the all-purpose flour with a gluten-free flour blend designed for baking. Keep in mind, texture may vary slightly, but the essence of the Funfetti Cake Recipe will still shine through.
How do I achieve the perfect buttercream consistency?
Beat the butter first until very smooth, then gradually add powdered sugar and milk. Adjust milk a teaspoon at a time until the frosting is creamy yet thick enough to hold its shape when spread.
Is this Funfetti Cake Recipe suitable for large gatherings?
Absolutely! This recipe makes enough to serve 12 generous slices, making it perfect for parties, birthdays, or any festive get-together. Plus, you can double or halve the recipe depending on your needs.
