Desserts
This 8-layer sponge cake recipe delivers ethereal, light-as-air layers that crumble like clouds between your fingers. The secret lies in precise technique—whisking eggs to ribbons, folding in flour with surgical patience, and baking at just the right temperature to create domes that deflate slightly as they cool. I've perfected this method over years of trial and error, and the results are always worth the effort.
The magic happens in the assembly: each layer gets a thin spread of vanilla buttercream before stacking, ensuring no dry spots or crumbly edges. For extra indulgence, I like to add a layer of raspberry jam between the vanilla sponge and buttercream, creating a delicate contrast of flavors. The cake must rest overnight in the fridge—this crucial step allows the layers to fully meld and the flavors to develop.
What you'll end up with is a towering, elegant cake that's surprisingly simple to make. The texture is the star here: tender, moist sponge that doesn't dry out, and light layers that separate cleanly when cut. This isn't just a cake—it's a showstopper that will impress even the most discerning dessert lovers. The vanilla bean magic makes all the difference, transforming basic ingredients into something extraordinary.
Perfect for celebrations or when you want to treat yourself to something special, this cake keeps beautifully for up to 5 days when stored properly. Let's get started on creating your masterpiece—layer by delicate layer. The patience will pay off in every bite.
Ingredients for 8 sponge cake
Twelve egg whites, vanilla beans, and patience create cloud-like layers that stack into showstopping beauty.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 12 whole | Room temperature, separated |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred for smoothness |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, plus extra for dusting |
| Unsalted Butter 🧈 | 1 cup | Room temperature, European style |
| Vanilla Bean 🌿 | 1 whole | Scraped seeds only, high quality |
| Heavy Whipping Cream 🥛 | 2 cups | Cold, full-fat for stability |
| Raspberry Jam 🍓 | ½ cup | Seedless, for filling layers |
| Vanilla Extract 🌸 | 2 tsp | Pure, not imitation |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Baking Powder 🍞 | ½ tsp | Aluminum-free |
| Powdered Sugar 🍚 | 3 cups | For buttercream |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The vanilla bean is non-negotiable here—Madagascar or Tahitian make all the difference. Williams Sonoma or Penzeys carry excellent options, but even your local specialty grocer should have a good one. If you can't find a whole bean, double the vanilla extract and add a pinch of vanilla sugar for depth. The egg whites need to be completely room temperature—cold whites won't whip properly. I've ruined batches by rushing this step, so take your time. For the butter, European-style (like Plugrá) has higher fat content and gives a richer flavor. If you're using regular butter, let it sit out for at least 2 hours.
No vanilla bean? Pure vanilla extract plus a pinch of vanilla sugar works in a pinch, though the flavor won't be as complex. The raspberry jam can be swapped for strawberry or apricot jam if that's what you have, but seedless is key—you don't want gritty texture between layers. For the buttercream, if you're short on powdered sugar, superfine sugar works at 1:1 ratio, but it'll be slightly grainier. The baking powder is crucial—aluminum-free is a must, as it can leave a metallic taste. If you're making this ahead, the dry ingredients (flour, sugar, baking powder) can be mixed in one bowl and stored for 1 week in an airtight container.
The cake needs 24 hours in the fridge to fully set—this is where the magic happens. Wrap tightly in plastic wrap, then foil to prevent drying. It keeps beautifully for 5 days this way, though the layers are best within 3 days. For serving, I like to dust with a little powdered sugar right before cutting. The buttercream can be made 1 day ahead and stored in the fridge, just whip it back up before assembling. The jam layer? Use it all up—it doesn't store well once opened, so plan accordingly.

Step-by-step instructions for light-as-air vanilla bean sponge cake
Here's how to make a delicate sponge cake that's light enough to float on air.
Separate and Whip Egg Whites to Stiff Peaks
Begin by separating the 12 whole large egg whites from the yolks, making sure no yolk touches the whites—that yolk will prevent those fluffy peaks we're after. In a spotless, grease-free bowl, whip the egg whites on medium speed until soft peaks form. Gradually add the 2.5 cups granulated sugar while whipping continuously, increasing speed to high once all sugar is incorporated.
Keep whipping until the meringue is glossy and holds stiff peaks when you lift the beaters—this usually takes about 5-7 minutes. The mixture should look thick and pale, almost like shaving cream. If you see any graininess, don't worry—just keep whipping until smooth. This step is crucial for that signature light, airy texture that makes this cake so special.
Fold in Dry Ingredients Gently
In a separate bowl, sift together the 2.5 cups all-purpose flour, 0.25 teaspoon salt, and 0.5 teaspoon baking powder. Scrape the vanilla seeds from the 1 whole vanilla bean and add them to the dry ingredients along with 2 teaspoons vanilla extract. Gently fold about one-third of this flour mixture into the meringue using a spatula, being careful not to deflate those precious air bubbles.
Add the remaining flour mixture in two more additions, folding just until combined. The batter should be thick but still hold its shape when lifted. Here's the thing—don't overmix. You want to maintain that lightness we worked so hard to create. The batter should look like thick, pale clouds when you're done. This is where the magic happens—proper folding keeps the cake tender and airy.
Prepare and Bake Three Thin Layers
Preheat your oven to 350°F and grease three 8-inch round cake pans lightly with the 1 cup unsalted butter, then dust them with flour. Divide the batter evenly among the pans—you'll need about one-third in each. Tap the pans gently on the counter to remove any air bubbles and ensure even baking.
Bake for 12-15 minutes, or until the tops spring back when touched lightly and a toothpick inserted comes out clean. The edges should be just starting to pull away from the pan, and the centers should look slightly domed. Rotate the pans halfway through baking for even browning. Don't overbake—this cake is delicate and will continue cooking slightly as it cools. Let the cakes cool in the pans for 5 minutes, then transfer to a wire rack to cool completely.
Prepare the Raspberry Filling and Buttercream
While the cakes cool, prepare the raspberry filling by gently heating the 0.5 cup raspberry jam in a small saucepan over low heat until it's smooth and spreadable. Remove from heat and stir in 1 tablespoon freshly squeezed lemon juice to brighten the flavor. Let it cool completely before using.
For the buttercream, beat the 1 cup unsalted butter at room temperature until smooth. Gradually add the 3 cups powdered sugar, then mix in the 2 teaspoons vanilla extract. Beat until light and fluffy—this should take about 3-4 minutes with an electric mixer. This buttercream needs to be smooth and spreadable, not grainy. If it's too thick, add a teaspoon of milk or cream to loosen it slightly.
Assemble the Cake with Confidence
Place the first cake layer on a cake stand or plate. Spread about 2 tablespoons of the cooled raspberry filling evenly over the top, leaving a ½-inch border uncovered. Repeat with the second layer, then the third. This layering technique ensures each bite has that perfect balance of cake and filling.
Spread a generous layer of buttercream over the top of the third cake layer, then use a spatula to smooth the sides. Chill the cake in the refrigerator for 30 minutes to help it set. Once firm, you can decorate with additional buttercream, fresh berries, or a dusting of powdered sugar. This cake is best served at room temperature, so let it sit for 15-20 minutes before slicing to enjoy those perfect, light-as-air layers.
Pro Tips For Making 8 Sponge Cake
- Whip Whites to Stiff: DESCRIPTION: Use a stand mixer with the whisk attachment and bump the speed to medium-high before adding sugar—this cuts down on the time it takes to get those egg whites glossy and holding peaks. I used to add sugar too early, and the whites would turn grainy on me; now I add it in two batches once they’re foamy.
- Sift Flour Like a Pro: DESCRIPTION: Don’t just dump the flour—sift it directly into the bowl after folding in the egg whites. This prevents dense pockets and makes the batter light as air. (Yes, even if you’re impatient like me—skip the sifting, and you’ll end up with a cake that’s more brick than sponge.)
- Butter Up the Pan: DESCRIPTION: Generously butter the cake pan and dust it with flour, then tap out the excess—this guarantees the cake won’t stick, even if you’re nervous about overbaking. I learned this the hard way when a cake tore apart at the edges because I skimped on the buttering.
- Split the Vanilla: DESCRIPTION: Scrape the seeds from half the vanilla bean into the batter, then steep the empty pod in the warm milk (if using) for 10 minutes. The seeds add depth, and the pod infuses the liquid with a subtle floral note—way better than just scraping all the seeds. (And no, you don’t need a fancy pod; a cheap one works fine.)
Troubleshooting this dish
Dense Cake Layers
If your sponge layers turn out dense instead of light and airy, it's likely due to overmixing the batter or underwhipped egg whites. Make sure your egg whites are whipped to stiff peaks—when you lift the beaters, the meringue should form a peak that doesn't flatten immediately. Also, fold the dry ingredients in gradually using a spatula in a gentle "J" motion to preserve those air bubbles. I've found that using a stand mixer on low speed helps prevent overmixing better than hand-whisking.
Cracked or Sunken Centers
Cracks or sunken centers usually mean your cake baked too long or the oven temperature was too high. Remove your cakes from the oven as soon as they spring back when touched lightly—this typically happens at 12-15 minutes for an 8-inch pan. If your oven runs hot, reduce the temperature by 25°F and use an oven thermometer to verify accuracy. I always tap the pans gently on the counter before baking to release air bubbles, which helps prevent uneven rising.
Batter Too Thin
A runny batter usually means you didn't whip the egg whites enough or added too much flour. Double-check that your meringue holds stiff peaks before folding in the dry ingredients. If your batter still looks too thin, let it rest in the bowl for 10-15 minutes—sometimes the flour absorbs moisture naturally. For extra insurance, chill the batter for 30 minutes before baking, which helps it hold its shape better in the oven.
Sticky or Gummy Texture
This often happens when cakes cool too quickly or don't dry out properly in the oven. Always let your cakes cool completely in the pans for 5 minutes, then transfer to a wire rack to finish cooling. If your cakes feel gummy when sliced, they likely need a bit more baking time—just 2-3 minutes longer can make a big difference. I also recommend brushing the tops with a light syrup (equal parts sugar and water) while they're still warm to help them set properly.
Filling Leaking Through
If your raspberry filling seeps through the layers, it means your cake wasn't fully cooled or the buttercream wasn't spread evenly enough to act as a seal. Always let your cake layers cool completely before assembling. When spreading the filling, leave a ½-inch border uncovered to prevent leaks. For extra stability, chill the assembled cake in the fridge for 30 minutes before decorating—this helps everything set and prevents messy surprises when slicing.
Cake Collapsing After Baking
Collapsed cakes usually result from opening the oven too soon or not letting the cakes cool properly in the pans. Once you remove them from the oven, let them cool in the pans for at least 5 minutes before transferring to a rack. Avoid moving them too soon—they need time to set. If your oven has hot spots, rotate the pans halfway through baking for even cooking. I also recommend using light-colored metal pans (like aluminum) for better heat distribution.

Frequently asked questions
Can I make this sponge cake without a stand mixer?
While a stand mixer makes whipping egg whites easier, you can achieve stiff peaks using hand beaters. Just use a clean, grease-free bowl and whip vigorously for 8-10 minutes—your arm will get a great workout! For folding the dry ingredients, use a rubber spatula and work gently to preserve those air bubbles. The key is patience and consistent motion.
How do I store leftover cake?
Wrap the entire cake tightly in plastic wrap, then place it in an airtight container. Store at room temperature for up to 2 days, or refrigerate for 5 days maximum. To serve, let it sit at room temperature for 15-20 minutes before slicing—this prevents crumbs and makes the layers more tender. For longer storage, freeze individual layers (without filling) for up to 1 month.
What's the best way to make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). Add 1 teaspoon xanthan gum to help bind the layers. For the buttercream, use a gluten-free powdered sugar. Keep in mind the texture will be slightly denser, but the vanilla flavor will still shine through. Test your blend first with a small batch to check for proper rising.
Can I substitute the raspberry jam for another fruit?
Yes! Any seedless jam or preserves will work—try strawberry, apricot, or even blackberry. For a non-fruit option, use a thin layer of lemon curd or chocolate ganache between layers. Just ensure your filling is completely cooled before assembling to prevent soggy layers. The key is using something with a smooth, spreadable consistency that won't leak through the cake.
Why does my cake need to rest overnight?
The overnight rest is crucial for two reasons: first, it allows the layers to fully absorb the filling and buttercream, preventing crumbs when slicing. Second, it lets the flavors meld together—you'll notice the vanilla and raspberry develop deeper complexity after resting. If you're in a hurry, a 4-hour refrigeration will help, but the full 24 hours gives the best results for texture and flavor.
