Ingredients List

For the funfetti cake:

2¾ cups all-purpose flour (substitute with cake flour for a lighter texture)
2½ teaspoons baking powder
½ teaspoon baking soda
1 teaspoon salt
1 cup (2 sticks) unsalted butter, softened
1¾ cups granulated sugar
4 large eggs, room temperature
2 teaspoons pure vanilla extract
½ teaspoon almond extract (optional, but enhances the “birthday cake” flavor)
1 cup buttermilk, room temperature
⅔ cup rainbow sprinkles (jimmies work best; avoid nonpareils as they tend to bleed)

For the vanilla buttercream:

1½ cups (3 sticks) unsalted butter, softened
5 cups powdered sugar, sifted
3 tablespoons heavy cream
2 teaspoons pure vanilla extract
¼ teaspoon salt
Additional ½ cup rainbow sprinkles for decoration

Timing

Step-by-Step Instructions

Step 1: Prepare Your Baking Environment

Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper. Pro tip: Spraying the pans before adding parchment ensures the paper stays in place while you pour the batter, reducing frustration and saving valuable prep time.

Step 2: Combine Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This pre-mixing technique ensures even distribution of leavening agents, preventing those disappointing pockets of unmixed baking powder that can cause bitter spots in your cake.

Step 3: Cream Butter and Sugar

In a large bowl using an electric mixer (or stand mixer with paddle attachment), beat the butter and sugar on medium-high speed for 4-5 minutes until light and fluffy. This extended creaming process incorporates air into your batter, creating that perfect tender crumb that sets homemade cakes apart from box mixes.

Step 4: Add Eggs and Extracts

Add eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Mix in the vanilla extract and almond extract (if using). The controlled addition of eggs prevents the mixture from curdling, which would result in a denser, less enjoyable cake texture.

Step 5: Alternate Dry Ingredients and Buttermilk

With the mixer on low speed, add the flour mixture in three additions, alternating with the buttermilk, beginning and ending with the flour mixture. Mix just until combined after each addition. Over-mixing activates gluten, which is the number one cause of tough, rubbery cakes according to professional bakers.

Step 6: Fold in Sprinkles

Gently fold in the rainbow sprinkles using a rubber spatula. Quick, light folding motions preserve both the air you’ve worked to incorporate and prevent the sprinkles from bleeding their colors throughout the batter. Reserve this step for the very end to maintain those vibrant rainbow pops.

Step 7: Bake and Cool

Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Allow cakes to cool in pans for 10 minutes before transferring to a wire rack to cool completely before frosting.

Use Greek yogurt instead of buttermilk to boost protein and reduce fat

Serving Suggestions

Elevate your funfetti cake recipe presentation with these creative ideas:

Serve with a scoop of vanilla bean ice cream for birthday celebrations
Create a dessert bar with different toppings (extra sprinkles, chocolate sauce, fresh berries)
Cut into small squares for a festive addition to brunch gatherings
Pair with coffee or milk for an afternoon pick-me-up
For adult gatherings, serve alongside champagne or prosecco for a whimsical contrast

Common Mistakes to Avoid

Using cold ingredients: Room temperature eggs, butter, and buttermilk blend more smoothly, creating a uniform batter (47% of baking fails are attributed to ingredient temperature issues)
Over-mixing the batter: Stop mixing as soon as ingredients are incorporated to prevent a tough, dense cake
Using the wrong sprinkles: Nonpareils will bleed throughout your batter; stick with jimmies or confetti sprinkles
Opening the oven door too early: This causes temperature fluctuations that lead to sunken cakes
Frosting warm cakes: Always allow cakes to cool completely to prevent melted, sliding frosting

Storing Tips for the Recipe

Maximize freshness with these storage strategies:

Unfrosted cake layers can be wrapped tightly in plastic wrap and stored at room temperature for up to 2 days
Frosted cake stays fresh under a funfetti cake dome at room temperature for 3-4 days
For longer storage, refrigerate frosted cake for up to 1 week, but bring to room temperature before serving for best flavor
Freeze unfrosted cake layers for up to 2 months; wrap in plastic wrap followed by aluminum foil
Make-ahead option: Prepare cake layers up to 1 month ahead, freeze, then thaw and frost the day before serving

FAQs

Can I make this cake a day ahead?
Absolutely! In fact, many bakers find the flavor develops nicely overnight. Just store it in an airtight container at room temperature.

Why did my sprinkles bleed into the batter?
You likely used nonpareils (tiny round sprinkles) instead of jimmies (the longer, rod-shaped sprinkles). Jimmies hold their color and shape better during baking.

Can I make this as a sheet cake instead of layers?
Yes! Use a 9×13-inch pan and bake for 30-35 minutes. Adjust frosting quantity down by about 25%.

Is it possible to make this recipe gluten-free?
Definitely. Substitute the all-purpose flour with a 1:1 gluten-free flour blend that contains xanthan gum for best results.

How can I prevent my cake layers from doming too much?
Use cake strips (damp cloth strips wrapped around the pans) or reduce the oven temperature to 325°F and bake for slightly longer.
