Whether you’re celebrating a birthday, a holiday, or just a regular Tuesday, this homemade Funfetti cake recipe is guaranteed to bring smiles to the table.

In this post, I’ll walk you through everything you need to know to make the best Funfetti cake at home. From the secret ingredients that make it extra fluffy to tips on ensuring those sprinkles are perfectly suspended in the batter, this guide covers it all. Let’s bake up some joy!

Why This Recipe is Better Than Boxed Mixes

While boxed Funfetti cake mix is convenient, there’s a world of difference when you make it from scratch. Homemade Funfetti cake has a richer flavor, a softer crumb, and the added benefit of knowing exactly what’s going into your dessert. No preservatives, no artificial flavors—just real, quality ingredients.

This recipe is crafted to achieve that classic Funfetti look and taste but with a few tweaks that elevate it to bakery-level quality. Here’s what makes it extra special:

1. Cake Flour for Softness: Using cake flour instead of all-purpose flour keeps the cake tender and gives it that cloud-like crumb we all love.
2. Buttermilk for Moisture: Buttermilk adds moisture and a slight tang that balances the sweetness, resulting in a perfectly moist cake.
3. Butter and Oil Combination: The butter adds rich flavor, while the oil helps keep the cake moist for days.
4. Vanilla Bean Paste: Instead of just regular vanilla extract, we’re using vanilla bean paste, which gives the cake a deeper, more aromatic vanilla flavor.

This Funfetti cake recipe is actually an adaptation of my Moist Vanilla Cake Recipe but with adjustments to create a stronger structure that keeps the sprinkles perfectly suspended, preventing them from sinking!

What You’ll Love About This Funfetti Cake Recipe

• Perfect Texture: This cake is fluffy, soft, and light, just like the Funfetti cake you remember, but with a homemade twist that makes it taste even better.
• Sprinkle Suspension: Ever had sprinkles sink to the bottom of a cake? Not with this recipe! We’ve perfected the batter to ensure that sprinkles stay evenly distributed throughout each layer.
• Bursting with Flavor: Using high-quality vanilla and the right balance of sugar ensures that every bite is flavorful without being too sweet.

Tips for Baking the Perfect Funfetti Cake

1. Measure Your Ingredients Carefully

Baking is a science, and accurate measurements make all the difference. For the best results, I recommend using a kitchen scale. Measuring your flour, sugar, and other ingredients by weight ensures that your cake has the right texture every time.

2. Use Room Temperature Ingredients

Room temperature ingredients—especially butter, eggs, and buttermilk—are crucial for achieving a smooth, evenly mixed batter. Cold ingredients won’t blend as well, which can lead to a denser cake. Take your ingredients out of the fridge about 1 hour before you start baking, or use these quick tips to bring them to room temp faster.

3. Don’t Overmix the Batter

Overmixing the batter can lead to a tough cake. Once you add the flour mixture to the wet ingredients, mix just until combined. This keeps the crumb soft and tender. The batter should be thick enough to suspend the sprinkles without being too dense.

4. Fold the Sprinkles in Gently

To ensure your sprinkles stay evenly distributed, toss them in a little flour before folding them into the batter. This simple trick helps prevent the sprinkles from sinking to the bottom. Be gentle when folding them in to avoid overmixing and to keep the colors from bleeding into the batter.

5. Bake at the Right Temperature

Baking at 350°F (177°C) allows the cake to rise steadily and bake through without forming a hard crust. If you find that your cakes often bake unevenly, consider investing in an oven thermometer. Oven temperatures can vary, and an accurate temperature reading helps prevent overbaking or underbaking.

How to Prevent Sinking Sprinkles in Your Cakes

One of the most common problems with Funfetti cakes is that they sometimes sink in the middle. If you’ve ever had this issue, you know how disappointing it can be. Here are some tips to help prevent this from happening:

1. Check Your Leavening Agents: Be sure you’re using the correct amounts of baking powder and baking soda. Too much leavening can cause the cake to rise too quickly and then collapse as it cools.
2. Don’t Open the Oven Door Early: Opening the oven door during the first 20 minutes of baking can cause the cake to sink. Let it bake uninterrupted to ensure a steady rise.
3. Test for Doneness: Insert a toothpick into the center of the cake; it should come out nearly clean. A few moist crumbs are okay.

Ingredients You’ll Need

One of the best things about this Funfetti cake recipe is that it uses simple, pantry ingredients. Here’s a rundown of what you’ll need and why each ingredient is important:

• Cake Flour (2 ⅓ cups): Cake flour has a lower protein content than all-purpose flour, which helps create a softer, lighter crumb. This is essential for a fluffy texture.
• Granulated Sugar (1 ¾ cups): Provides sweetness and also helps with moisture.
• Baking Powder & Baking Soda (1 ½ tsp baking powder and ½ tsp baking soda): These leavening agents help the cake rise and keep it light. The combination of baking powder and baking soda balances with the acidity of the buttermilk.
• Butter (6 oz): Adds richness and flavor. Make sure it’s softened to room temperature for easy mixing.
• Large Eggs (3 eggs + 1 egg white): The whole eggs provide structure, while the additional egg white helps keep the cake light and airy.
• Vanilla Bean Paste (2 tbsp): For that intense vanilla flavor that really makes the Funfetti cake shine. Vanilla extract works too, but vanilla bean paste adds a deeper flavor and beautiful specks throughout the cake.
• Buttermilk (¾ cup): Buttermilk makes the cake tender and adds a subtle tang, balancing out the sweetness.
• Vegetable Oil (4 tbsp): Keeps the cake moist and soft, even after it’s been refrigerated.
• Rainbow Sprinkles (jimmies) (½ cup): Be sure to use “jimmies” or rod-shaped sprinkles, as they don’t bleed into the batter as nonpareils would.

How to Make Funfetti Cake: Step-by-Step Guide

Step 1: Preheat and Prepare Your Pans

Preheat your oven to 350°F (177°C). Grease and flour three 6-inch or two 8-inch round cake pans. You can also line the bottoms with parchment paper for easier removal.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the dry ingredients: cake flour, baking powder, baking soda, and salt. Set the bowl of dry ingredients aside.

Step 3: Add the Butter

In a large mixing bowl or the bowl of a stand mixer, combine softened butter, granulated sugar, and vegetable oil. Beat these ingredients on medium-high speed for 3 to 5 minutes until the mixture becomes light, fluffy, and pale in color. This creaming step is crucial, as it incorporates air into the batter, creating a lighter texture.

Step 4: Combine the Wet Ingredients

Once the butter, sugar, and oil are well creamed, add the eggs. Use 3 large eggs plus 1 additional egg white, adding them one at a time and beating well after each addition to ensure they’re fully incorporated. Then, add 2 tablespoons of vanilla bean paste, blending it into the mixture until smooth.

Step 5: Incorporate the Wet and Dry Mixtures

With your mixer on low speed, it’s time to combine the dry ingredients and buttermilk. Begin by adding one-third of the dry ingredients to the creamed butter mixture, mixing just until combined. Then add half of the buttermilk, mixing again until smooth. Repeat with another third of the dry ingredients, then the remaining buttermilk, and finish with the last third of the dry ingredients. Mixing after each addition just until combined is key to preventing overmixing, which could lead to a denser cake texture.

Step 6: Fold in the Sprinkles

Toss the rainbow sprinkles with a bit of flour (about 1 tablespoon) to help them suspend in the batter without sinking. Gently fold the sprinkles into the batter, being careful not to overmix, as this could break the sprinkles and cause them to bleed.

Step 7: Divide and Bake

Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula for even baking. Bake for 22-25 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.

Step 8: Cool Completely

Let the cakes cool in their pans for 10 minutes, then carefully turn them out onto a wire rack to cool completely before frosting.

Funfetti Cake FAQ

Can I use different types of sprinkles in this recipe?

Yes, but for the best results, stick to jimmies or rod-shaped sprinkles, as they hold up well in the batter and don’t bleed color. Nonpareils (the tiny round sprinkles) can dissolve and create streaks of color, so it’s best to avoid them in the batter. If you want extra decoration, save the nonpareils for garnishing the frosted cake.

Can I make cupcakes with this Funfetti cake recipe?

Yes, you can make cupcakes with this batter! However, for the best cupcake results, we recommend using our Funfetti Cupcake Recipe, which is specially adapted to produce perfectly domed tops and even rise, all while keeping that same delicious Funfetti flavor.

How do I keep the sprinkles from sinking to the bottom?

To help keep sprinkles evenly distributed, toss them in a small amount of flour (about 1 tablespoon) before folding them into the batter. This helps the sprinkles “stick” to the batter, preventing them from sinking during baking.

What’s the best way to store Funfetti cake?

Store leftover Funfetti cake in an airtight container at room temperature for up to 2 days. For longer storage, you can refrigerate the cake for up to 5 days, or freeze individual slices for up to 2 months. Wrap each slice in plastic wrap and place it in a freezer-safe bag before freezing.

Can I make this recipe ahead of time?

Absolutely! You can bake the cake layers a day ahead. Just wrap each cooled cake layer tightly in plastic wrap and store it at room temperature or in the freezer. When you’re ready to frost and assemble, simply unwrap the frozen cakes and proceed as usual, no need to defrost first. The cake will defrost as you decorate, and it will settle beautifully in the fridge.

Can I make this Funfetti cake gluten-free?

Yes, you can substitute the cake flour with a gluten-free all-purpose baking flour. Make sure it’s a blend designed for 1-to-1 substitution with regular flour, as this will yield the best texture and rise. Note that gluten-free versions may have a slightly different crumb but should still be delicious!

How to Frost Your Cake Perfectly
