Desserts
A 1-pound sponge cake delivers elegant layers without the fuss of multiple pans—just one bowl and a single baking sheet. This classic Genoise method creates a light, airy texture perfect for layer cakes, trifles, or even solo slices. The secret lies in properly whipped egg whites and gentle folding, ensuring every bite stays tender and moist.
This recipe uses simple ingredients you likely already have: eggs, sugar, flour, and a touch of vanilla. The process is straightforward—whisk eggs and sugar until pale and thick, fold in flour gently, and bake at 350°F for 25-30 minutes. No special tools required, just patience and a steady hand for folding.
What you’ll end up with is a 1-pound cake that’s light enough to float, with a delicate crumb and subtle sweetness. Split into layers for a classic French-style cake, or enjoy it whole with a dusting of powdered sugar. The possibilities are endless, whether you’re building a multi-tiered dessert or keeping it simple.
For extra flair, brush layers with simple syrup or fill with whipped cream. The cake’s neutral flavor also pairs beautifully with fruit compotes, chocolate ganache, or even a dusting of citrus zest. Ready to master this timeless technique?
Ingredients for 1 pound sponge cake
Classic Genoise ingredients for a cake so light it practically floats—just eight staples for perfect layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 6 whole | Room temperature preferred |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for best texture |
| Pure Vanilla Extract 🌿 | 1 tsp | Or vanilla bean paste |
| Unsalted Butter 🧈 | ½ cup | Melted, room temperature |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Cream of Tartar 🧂 | ¼ tsp | For egg white stability |
| Powdered Sugar 🍚 | ¼ cup | For dusting finished cake |
The eggs are non-negotiable here—room temperature is key. Store-bought cartons work fine, but if you're using farm-fresh, let them sit out for 30 minutes first. Granulated sugar matters too: domestic brands like Domino or C&H dissolve smoothly, while raw or turbinado can leave grit. Flour? King Arthur or Gold Medal are my go-tos—they're sifted and consistent. Pro tip: Weigh your flour if you can—cups vary wildly by brand.
No vanilla extract? Vanilla bean paste adds flecks, or scrape seeds from a pod. Butter can be swapped for vegetable oil at half the amount, but melted butter adds richness. Cream of tartar stabilizes the egg whites—skip it only if you have fresh lemon juice (use 1 tsp). For a citrus twist, add 1 tsp lemon zest to the batter. The powdered sugar is purely decorative, but trust me—it makes everything feel special.
Store the cake in an airtight container with parchment between layers to prevent drying. Keeps 3 days at room temperature or 1 week refrigerated. For longer storage, wrap tightly in plastic and freeze—up to 3 months. Thaw at room temperature before serving. The cake's delicate texture means it's best enjoyed fresh, but the flavor actually improves slightly after 24 hours as the crumb settles.

Step-by-step instructions for light-as-air one-pan sponge cake
This method delivers perfectly airy layers with minimal effort—just follow these precise steps.
Prepare the Egg Mixture for Maximum Volume
Separate the 6 whole Large Eggs into yolks and whites, placing each in separate bowls. Add 1.5 cups Granulated Sugar to the yolks and beat with a hand mixer on medium-high speed for 3-4 minutes until the mixture is pale, thick, and nearly tripled in volume. This step is critical—it incorporates air that will create the cake's signature lightness.
In a separate, spotless bowl, beat the egg whites with the 0.25 tsp Cream of Tartar and 0.25 tsp Salt until soft peaks form. Gradually add the remaining 1.5 cups All-Purpose Flour in three additions, folding gently with a spatula to maintain air pockets. The flour should be sifted first to prevent dense layers.
Combine Wet Ingredients for a Smooth Batter
Melt the 0.5 cup Unsalted Butter in a microwave-safe bowl in 20-second intervals, stirring between each, until fully liquid but not hot. Let it cool slightly, then mix it into the yolk mixture along with the 1 tsp Pure Vanilla Extract. The butter should be warm but not steaming—this ensures proper emulsification without scrambling the eggs.
Gently fold one-third of the egg white mixture into the yolk mixture to lighten it, then carefully fold in the remaining egg whites in two additions. Use a spatula to create a ribbon effect, cutting through the center and folding from the bottom up. This technique maintains maximum air incorporation for that signature sponge texture.
Bake at Precise Temperature for Even Rise
Preheat your oven to 350°F and grease a 9-inch round cake pan thoroughly with butter and flour. Pour the batter into the prepared pan and smooth the top with a spatula. Tap the pan gently on the counter 3-4 times to release any large air bubbles that might have formed during mixing.
Bake for 30-35 minutes until the top springs back when pressed gently with a finger and a toothpick inserted into the center comes out clean. The edges should be light golden brown, but the center should remain pale—overbaking leads to dryness. Rotate the pan halfway through baking for even heat distribution.
Cool and Dust for Perfect Presentation
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then invert it onto a wire rack to cool completely. This gradual cooling prevents cracking and maintains the delicate structure. Once fully cooled, dust the top generously with 0.25 cup Powdered Sugar using a fine-mesh sieve for an elegant finish.
The cake should rise slightly as it cools, creating those coveted airy layers. Slice carefully with a serrated knife for clean cuts, and serve immediately or store in an airtight container for up to 3 days. This method guarantees a light, tender crumb that's perfect for layering with fillings or enjoying on its own.
Pro Tips For Making 1 Pound Sponge Cake
- WHISK EGGS TO LUKEWARM: I learned this the hard way—cold eggs from the fridge won’t incorporate properly, and you’ll end up fighting the mixer. Let them sit in warm water for 10 minutes first, then whisk until the yolks and whites are just slightly thicker than cold milk. This makes the butter and sugar blend silky smooth, not grainy.
- MELT BUTTER FIRST: Skip the cold butter shortcut—this isn’t a cookie. Melt your ½ cup unsalted butter (just enough to coat the pan) and brush it hot into the pan before baking. The residual heat helps the cake rise faster and gives you a golden crust without overbaking. (Yes, even if you’re impatient like me.)
- WEIGH YOUR FLOUR: Scooping flour from the bag is the fastest way to end up with a dense, dry cake. Spoon the flour into a scale, then gently level it off—no packing, no tapping. For a 1-pound cake, you’ll use about 1 cup minus 2 tablespoons. Trust me, the difference in texture is night and day.
- BAKE UNTIL 195°F: Your oven runs hotter than you think, and sponge cake needs that internal temp to set properly. Test with a skewer—it should come out clean, but the center should still feel slightly springy, not rubbery. If you pull it too soon, it’ll collapse as it cools. (I know, I’ve cried over this cake before.)
Wine and beer pairings for 1 pound sponge cake
Crisp White Wine
For this delicate sponge cake, I always reach for a dry Riesling or Sauvignon Blanc—their bright acidity and citrus notes complement the cake’s subtle vanilla and butter flavors without overpowering it. A German Riesling like Dr. Loosen ‘Blue Slate’ (around $20) has enough minerality to stand up to the powdered sugar finish. Chill it to 45-50°F before serving to enhance its refreshing contrast. 🍷
Sweet Sparkling Wine
A Prosecco or Moscato d’Asti adds a festive touch to your cake presentation. The effervescence cleanses your palate between bites, making each slice feel special. I love La Marca Prosecco (around $15) for its crisp apple and pear notes—it’s light enough to pair with the cake’s airy texture. Serve it slightly chilled (40-45°F) in small coupe glasses for an elegant dessert moment. ✨
Light Beer Pairings
If you prefer beer, a Belgian Witbier like Hoegaarden (around $10) works surprisingly well. Its coriander and orange peel notes bridge the cake’s vanilla and butter, while the slight sweetness balances the powdered sugar. For a darker option, try a wheat beer like Blue Moon—its caramel and citrus undertones harmonize beautifully with the cake’s buttery richness. Serve both at 45-50°F to enhance their refreshing qualities. 🍺
Dessert Wine Harmony
For a more indulgent pairing, a late-harvest Riesling or Moscato brings complementary sweetness to the cake’s delicate flavor. I adore Chateau Ste. Michelle Late Harvest Riesling (around $18)—its honeyed notes mirror the cake’s subtle sweetness while its acidity keeps the palate fresh. Serve it slightly cooler (40-45°F) to let its floral aromas shine alongside the powdered sugar finish. 💛
Coffee or Tea Contrast
If you’re serving the cake as a standalone dessert, a lightly sweetened espresso or Earl Grey tea creates a sophisticated contrast. The bitterness of coffee cuts through the cake’s richness, while the bergamot in Earl Grey adds a citrusy brightness. For tea, I recommend Earl Grey with a splash of honey—it’s simple but elevates the entire experience. 🍵

Frequently asked questions
Can I make this sponge cake without a stand mixer?
Use a hand mixer or even whisk the egg whites vigorously until stiff peaks form. For the yolks, beat them with a hand mixer on high for 5-6 minutes until pale and thick. The key is patience—whisking by hand just takes more elbow grease. A spotless bowl is critical to avoid deflating the whites.
Why did my cake sink in the middle?
This usually happens from one of three issues: overmixing the batter (breaking air pockets), opening the oven too soon (causing sudden cooling), or underbaking. Always bake until a toothpick comes out clean, and let the cake cool gradually in the pan for 10 minutes before removing. A water bath (baking pan with 1 inch of hot water in the bottom) can also help prevent sinking.
How do I adjust this recipe for a 9x13-inch pan?
For a single-layer cake, increase the batter by 50% (use 9 eggs, 2.25 cups sugar, 2.25 cups flour, etc.) and bake at 325°F for 40-45 minutes. For a 9x13-inch pan, the cake will be thicker—slice it into squares for easy serving. Line the pan with parchment paper for easier removal.
Can I substitute cake flour for all-purpose flour?
Yes! Replace the 1.5 cups all-purpose flour with 1.25 cups cake flour (or 1.5 cups minus 2 tablespoons all-purpose flour). Cake flour has a lower protein content, resulting in a more tender crumb. If you don’t have cake flour, mix 1.5 cups all-purpose flour with 2 tablespoons cornstarch and sift well. This substitution works especially well for layer cakes.
How do I store leftover sponge cake?
Wrap the cake tightly in plastic wrap or place it in an airtight container with parchment paper between layers. It stays fresh at room temperature for 3 days or refrigerated for 1 week. For longer storage, freeze the cake (wrapped) for up to 3 months. Thaw at room temperature before serving—never microwave, as it can make the cake gummy.
