Ingredients You’ll Need

Getting the perfect Funfetti Cake Recipe starts with a handful of simple but essential ingredients. Each one plays a crucial role in creating the cake’s light, moist texture and its classic fun look with sprinkles baked right in.

• Unsalted butter (1 cup, room temp): Creaming this thoroughly with sugar gives the cake a tender crumb and rich flavor.
• Granulated sugar (2 cups): Sweetens the cake while contributing to its soft texture.
• Vegetable or canola oil (1/2 cup): Adds moisture so the cake stays delightfully soft.
• Large eggs (4, room temp): Provide structure and help the cake rise beautifully.
• Vanilla extract (1 tbsp): Enhances the overall flavor with warm, sweet notes.
• All-purpose flour (3 1/4 cups): The base that holds everything together.
• Baking powder (2 1/2 tsp): Gives the cake its light lift and fluffiness.
• Baking soda (1/2 tsp): Works with acidic ingredients to create the perfect rise.
• Salt (1 tsp): Balances sweetness and deepens flavor.
• Full fat sour cream (1/2 cup, room temp): Adds richness and a subtle tang, keeping the crumb moist.
• Buttermilk (1 cup, room temp): Reacts with baking soda to give a tender texture and slight tang.
• Rainbow jimmies sprinkles (3/4 cup): The star of the show—sprinkles that burst with color and fun through every bite.
• Butter for frosting (1 1/2 cups, room temp): Creates a creamy base for the luscious buttercream.
• Powdered sugar (5 cups): Sweetens and thickens the frosting to the perfect consistency.
• Vanilla extract for frosting (1 tbsp): Adds depth and warmth to the buttercream.
• Milk (2-3 tbsp): Adjusts frosting texture for easy spreading.
• Sprinkles for decorating (1/2 cup): A final pop of color on top, making the cake as festive on the outside as the inside.

How to Make Funfetti Cake Recipe

Step 1: Prepare Your Pans and Oven

Start by preheating your oven to 350°F and grease three 9-inch cake pans, then line the bottoms with parchment paper. This step ensures your cakes release easily once baked. If using 8-inch pans, remember to leave out some batter to avoid the cakes sinking.

Step 2: Mix Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Combining them first helps these rising agents distribute evenly throughout the batter for a perfect lift.

Step 3: Cream Butter and Sugar

Using a hand or stand mixer fitted with a whisk attachment, cream together the softened butter and granulated sugar on medium-high speed until the mixture becomes light and fluffy—this usually takes about 3 to 5 minutes and is key to a tender cake texture.

Step 4: Add Oil and Eggs

While the mixer runs on low, slowly add in the oil, then scrape down the sides of the bowl to keep everything well combined. Next, add the eggs one by one, mixing gently after each addition, followed by the vanilla extract. This careful incorporation prevents the batter from breaking.

Step 5: Incorporate Sour Cream, Buttermilk, and Dry Ingredients

Now mix in the sour cream. Then, add the dry ingredients and buttermilk alternately to the batter, starting and ending with the dry ingredients. This alternating method keeps your batter smooth and prevents overmixing, which can lead to a dense cake.

Step 6: Fold in the Sprinkles

Remove the bowl from your mixer and gently fold the rainbow jimmies sprinkles into the batter using a rubber spatula. Folding keeps the sprinkles from melting completely and turning your batter pastel—it’s all about keeping that vibrant confetti look.

Step 7: Bake to Perfection

Divide the batter evenly into the pans and smooth the tops. Bake 9-inch pans for 30 to 35 minutes or 8-inch pans for 35 to 40 minutes. The cakes are done when a toothpick comes out clean and the tops bounce back when lightly pressed.

Step 8: Cool and Chill

Allow the cakes to cool in the pans for 30 minutes, then carefully remove them onto a wire rack. Peel off the parchment and chill the cakes in the fridge for about an hour if frosting the same day. This chilling step is crucial to achieve clean frosting layers later.

Step 9: Make the Buttercream Frosting

Beat the butter until smooth, then gradually add powdered sugar, vanilla, and milk until the frosting is creamy and spreadable. Adjust the milk quantity to achieve the perfect consistency for frosting the cake seamlessly.

Step 10: Assemble and Decorate

Level the cakes if necessary and spread a thin layer of buttercream between each cake layer. Apply a thin crumb coat over the entire cake and chill to set. Then, finish frosting with the remaining buttercream and sprinkle extra jimmies on top for that final festive flourish.

How to Serve Funfetti Cake Recipe

Garnishes

Adding a sprinkle of the colorful jimmies on top is a classic, but you can also serve slices with a dollop of whipped cream or a few fresh berries to complement the sweetness while keeping the presentation fun and lively.

Side Dishes

Pair this cake with a scoop of vanilla ice cream or a glass of cold milk for a comforting duo. For a more grown-up twist, a cup of rich coffee or a light fruity tea also pairs beautifully with the buttery, vanilla-infused sweetness of the cake.

Creative Ways to Present

Try layering cupcakes with the same funfetti batter and frosting for personalized mini treats or transform the cake into a layered trifle with alternating layers of cake, whipped cream, and fresh fruit. The colorful sprinkles make every presentation pop with excitement!

Make Ahead and Storage

Storing Leftovers

Once frosted, keep leftover Funfetti Cake refrigerated in an airtight container to maintain moisture and freshness. It will stay good for up to 4 days without losing that wonderful softness or festive appeal.

Freezing

You can freeze unfrosted cake layers wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw them overnight in the fridge before applying frosting to preserve the texture and taste as if freshly baked.

Reheating

If you prefer your cake at room temperature, just take it out of the fridge about 30 minutes before serving. For a warm slice experience, heat in the microwave for 10-15 seconds—just enough to make the cake soft and the buttercream slightly melty.

FAQs

Can I use regular sprinkles instead of rainbow jimmies?

Absolutely! While rainbow jimmies hold up best during baking because they don’t melt as much, you can use other sprinkles too. Just keep in mind that some might bleed color and affect the batter’s hue.

Is there a substitute for buttermilk in this Funfetti Cake Recipe?

Yes, you can make a buttermilk substitute by combining 1 cup of milk with 1 tablespoon of lemon juice or white vinegar. Let it sit for 5 minutes before adding to the batter to get the same tenderizing effect.

Why is the cake sinking in the middle sometimes?

This often happens when pans are overfilled or the oven temperature isn’t quite right. Filling pans just over halfway and checking that your oven heats accurately helps prevent sinking centers.

Can I make this recipe gluten-free?

With some adjustments, yes! Substitute all-purpose flour with a gluten-free blend designed for baking. Be sure it includes xanthan gum or another binder to mimic the structure gluten provides.

How long does the cake take to bake if using smaller pans?

Smaller pans may require less baking time—start checking for doneness around 25 minutes. Use a toothpick inserted in the center as your guide; if it comes out clean, your cake is ready!
