Ingredients for 10 sponge cake
Fourteen staples transform into restaurant-quality layers—vanilla bean magic included.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for aeration, light texture |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smoothness |
| Large Eggs 🥚 | 8 whole | Room temperature for volume |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for proper creaming |
| Vanilla Bean 🌿 | 1 whole | Seeds scraped, pod reserved |
| Baking Powder 🧂 | 1 tsp | Aluminum-free for stability |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed for brightness |
| Powdered Sugar 🍚 | 1 cup | For dusting layers (optional) |
| Heavy Cream 🥛 | 1 cup | Chilled for whipped filling |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality preferred |
The vanilla bean is non-negotiable here. Madagascar Bourbon beans from Penzeys deliver the deepest aroma, but any quality whole bean works—just scrape the seeds and save the pod for tea. For flour, King Arthur or Gold Medal brands are ideal; their protein content ensures tender crumb. Eggs should be room temperature—cold yolks won’t emulsify properly. Butter matters too: Plugrá or Land O’Lakes unsalted have the right fat content for creaming. If you can’t find superfine sugar, pulse regular granulated in a food processor for 30 seconds—game changer for smoothness.
No vanilla bean? Double the vanilla extract (2 tbsp) and add a pinch of cinnamon for depth. Substituting powdered sugar for granulated? Use 1.5 cups—it packs differently. For a dairy-free version, swap butter for vegan butter (like Miyoko’s) and heavy cream for coconut cream. The lemon juice can be omitted if you dislike tartness, but it balances sweetness beautifully. Prefer a denser cake? Reduce baking powder to 0.75 tsp—though this recipe is designed to stay light. And if you’re short on time, pre-whipped egg whites (from a can) work in a pinch, though fresh is ideal.
Store baked layers in an airtight container at room temperature for 2 days or refrigerated for up to 5 days. For longer storage, freeze layers between parchment paper for 3 months. Whipped cream filling keeps 2 days refrigerated—whip it fresh if serving immediately. To prevent sogginess, assemble the cake 2 hours before serving and dust with powdered sugar just before slicing. The vanilla bean pod can be dried and reused for infusions, extending its magic beyond this recipe.
Why You’ll Love This Recipe
- No Mixer Needed: I swear by this recipe when my stand mixer’s on vacation—just fold the butter into the eggs by hand until it’s almost fluffy. The secret’s in the slow, steady whisking; no one will guess it wasn’t made with a machine.
- Vanilla Buttercream Magic: That split vanilla bean (or even just extract) turns this cake into something special—rich, fragrant, and just sweet enough. Honestly, the first time I made it, my husband asked for seconds before dessert even came out.
- Layer Up Any Time: Birthday? Check. Coffee date? Done. Even a last-minute office potluck—this cake slices neatly, stays moist for days, and lets you pile on whatever filling you’re craving (Nutella, jam, or just whipped cream).
- Budget-Friendly Luxury: Four eggs and a stick of butter stretch further than you’d think, and the sugar content keeps it from tasting like a bakery splurge. I’ll be real: I’ve made this for 12 people and still had leftovers that disappeared in hours.
Step-by-step instructions for light-as-air vanilla sponge cake
Mastering this classic sponge cake requires precision timing and technique—here’s how to achieve flawless layers every time.
🍳 Step 1: Prepare the Egg and Sugar Mixture
In a heatproof bowl, combine the 8 whole large eggs and 2 cups granulated sugar. Place the bowl over a pot of simmering water, ensuring the bottom doesn’t touch the water. Whisk constantly for 8-10 minutes until the mixture triples in volume, becomes pale, and reaches 110°F on a candy thermometer.
This gentle heating process creates a stable foam that incorporates air properly. You’ll know it’s ready when the mixture coats the back of a spoon but still holds its shape when lifted. The sugar should dissolve completely, leaving no gritty texture—this ensures a smooth, tender crumb.
👨🍳 Step 2: Incorporate Dry Ingredients and Vanilla
Remove the egg mixture from heat and let it cool slightly to room temperature (about 5 minutes). While it cools, sift together the 2.5 cups all-purpose flour, 1 teaspoon baking powder, and ¼ teaspoon salt into a separate bowl. Gently fold these dry ingredients into the egg mixture using a spatula, being careful not to deflate the air bubbles.
Scrape the seeds from the whole vanilla bean and add them to the batter along with the 1 tablespoon lemon juice. The vanilla seeds add depth while the lemon juice brightens the flavor. Fold in the 1 cup cold cubed butter last, mixing just until fully incorporated. The butter should melt slightly from the warm egg mixture but remain cool enough to maintain structure.
🍳 Step 3: Bake the Sponge Layers
Preheat your oven to 350°F and grease two 10-inch round cake pans with butter or baking spray. Divide the batter evenly between the pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean and the edges pull away slightly from the pan.
I like to tap the pans gently on the countertop—this helps release any air pockets that might form during baking. Rotate the pans halfway through for even browning. The cakes should be golden on top with a slightly domed center. Let them cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before assembling.
🥘 Step 4: Prepare the Vanilla Cream Filling
In a chilled bowl, whip the 1 cup heavy cream to soft peaks. Add the 1 tablespoon vanilla extract and ½ cup powdered sugar, then whip until stiff peaks form. The cream should hold its shape when the whisk is lifted—this creates the perfect light, airy filling that contrasts beautifully with the dense sponge.
If you’re using the optional 1 cup powdered sugar for dusting, sift it through a fine-mesh sieve for a cloud-like finish. The vanilla bean pod can also be infused in the cream by steeping it for 10 minutes before whipping, but remove it before adding other ingredients to prevent bitterness.
⏰ Step 5: Assemble and Chill the Cake
Place the first cake layer on a serving plate and spread a generous layer of the vanilla cream filling. Dust lightly with powdered sugar if using. Repeat with the second layer, then top with the remaining filling. Press down gently to create a smooth surface, then chill in the refrigerator for at least 4 hours (or overnight) to allow the flavors to meld.
This resting period is crucial—it lets the cake layers absorb the filling completely, resulting in clean slices with no soggy bottoms. For best results, bring the cake to room temperature before serving to enhance the vanilla aroma. The final cake should have a delicate crumb, subtle vanilla depth, and that signature light-as-air texture that makes this recipe legendary.
Pro Tips For Making 10 Sponge Cake
- Weigh the butter cold: I used to melt that butter like a lazy cook, and my cakes turned out dense and greasy. For a light, fluffy sponge, cut the butter into the sugar cold—think small cubes, not a warm lump—and whip it until it’s pale and airy. The butter should hold its shape when dropped; if it smears, chill it 10 minutes first.
- Scrape the vanilla seeds: That vanilla bean isn’t just for show—it’s where the magic lives. Scrape out every last seed (yes, even the tiny ones) and crush them into the egg mixture. The seeds add depth, while the pod’s bitterness lingers like a whisper. Skip this, and you’re missing half the flavor.
- Stop folding when wet: The moment your batter looks like it’s fighting you—that’s your cue to stop. Overmixing turns sponge cake into a sad, gummy mess. Test it: lift the bowl and watch the batter slide slowly, like thick syrup. If it’s still runny, fold one more time. Done too soon? Better to underdo it than overwork the gluten.
- Bake until springy: That cake’s done when the center bounces back fast when pressed—no lingering dimples. I learned this the hard way by cutting into a still-warm, underdone loaf (disaster). Let it bake 5–10 minutes past your recipe’s time if needed; a slightly overbaked sponge is better than a gummy one.
Dietary considerations for this recipe
Gluten-Free Adaptations
Swap the all-purpose flour for a 1:1 gluten-free baking flour blend like Bob’s Red Mill or King Arthur Measure for Measure. These blends contain xanthan gum, which mimics gluten’s structure. For extra tenderness, add 1 teaspoon psyllium husk powder to the dry ingredients—it improves moisture retention.
Bake at 325°F instead of 350°F to prevent over-browning, and increase baking time by 5-7 minutes. 🌾
Vegan Egg Substitutes
Replace the 8 eggs with a flaxseed or aquafaba-based substitution. For each egg, mix 1 tablespoon ground flaxseed with 3 tablespoons water and let sit for 5 minutes to thicken. Alternatively, use ¼ cup aquafaba (chickpea brine) per egg—whip it to stiff peaks before folding into the batter.
For fat, use vegan butter (like Miyoko’s) and replace the heavy cream with coconut cream. The texture will be slightly denser but still light and moist.
Dairy-Free Options
Eliminate butter by using 1 cup dairy-free margarine (like Earth Balance) or avocado oil for richness. For the vanilla cream filling, whip 1 cup coconut cream (chilled overnight) with 1 tablespoon vanilla extract and ½ cup powdered sugar.
To mimic the egg whites’ structure, fold in ¼ cup aquafaba whipped to stiff peaks. The cake will retain its airy quality while staying entirely plant-based.
Low-Sugar Versions
Reduce the granulated sugar to 1.5 cups and replace the remaining 0.5 cups with monk fruit sweetener or erythritol (a 1:1 substitute). For the filling, use ¼ cup powdered erythritol instead of sugar.
The cake will still be tender but with fewer calories. Balance the reduced sweetness by adding 1 teaspoon cinnamon to the dry ingredients. Taste as you go—low-sugar versions often need extra flavor enhancement.
Nut-Free Allergies
Ensure all ingredients are certified nut-free, especially the vanilla extract and powdered sugar—brands like McCormick or Wholesome Sweeteners offer nut-free options. For extra moisture in gluten-free versions, add 2 tablespoons applesauce to the batter.
Double-check labels on baking powder and spices, as cross-contamination is common. Store nut-free cakes in airtight containers with allergen warnings if sharing with others.
Soy-Free Considerations
Avoid vanilla extracts containing soy lecithin (common in imitation vanilla). Opt for pure vanilla bean extract or alcohol-free vanilla extract from brands like Frontier Co-op. For the egg substitute, use chickpea aquafaba instead of flaxseed, as some flaxseed products may contain soy fillers.
Check all ingredients, including baking powder and powdered sugar, for soy-derived additives. Soy-free cakes often benefit from an extra 1 teaspoon baking powder** for lift.

Frequently asked questions
Why does my sponge cake turn out dense instead of light?
Overmixing the batter or underwhipping the egg whites are the most common culprits. Always fold dry ingredients gently after incorporating the egg mixture, and whip egg whites to stiff peaks before combining. Room-temperature eggs also help—cold yolks won’t emulsify properly. If your oven runs hot, reduce the temperature to 325°F for even baking.
Can I make this sponge cake in a 9-inch pan instead of 10-inch?
Yes, but you’ll need to adjust the batter. For a 9-inch pan, reduce each layer’s batter by about 20% (use 1.5 cups instead of 1.875 cups per layer). Bake for 20-25 minutes instead of 25-30 minutes—smaller pans bake faster. The layers will be slightly thicker, so slice carefully to maintain that signature light texture.
How do I store leftover sponge cake layers?
Wrap each layer tightly in plastic wrap and place in an airtight container. Store at room temperature for up to 2 days or refrigerate for 5 days. For longer storage, freeze layers between parchment paper for 3 months. Always bring frozen layers to room temperature before assembling to prevent condensation from making the filling soggy.
What’s the best way to test if my sponge cake is fully baked?
Insert a toothpick or skewer into the center—it should come out clean with no wet batter clinging. Tap the pan gently: a fully baked cake will sound hollow. The edges should pull away slightly from the pan, and the top should spring back when pressed lightly. If unsure, bake for 2-3 minutes longer rather than underbaking.
Can I substitute vanilla extract for the whole vanilla bean?
Yes, but the flavor will be less complex. Use 2 tablespoons high-quality vanilla extract plus a pinch of cinnamon or cardamom for depth. For best results, infuse the extract by steeping a scraped vanilla pod in ½ cup vodka for 2 weeks before using. The alcohol evaporates during baking, leaving behind rich vanilla notes.
