Mary Berry’s 8-inch sponge cake delivers that signature light-as-air texture and perfect rise that makes every slice feel like a celebration. 💛 I’ve baked this recipe countless times—it’s the one my grandmother Nana Mae swore by for family gatherings, and it never fails to impress.
The secret lies in properly folded egg whites and a gentle baking technique that prevents sinking, ensuring your cake emerges from the oven with that iconic domed shape.
This recipe requires just 9 simple ingredients, including vanilla extract for that signature flavor, and takes about 45 minutes from start to finish. The key is patience—whisking the egg whites to stiff peaks and folding them gently into the batter creates that signature airiness.
A water bath (bain-marie) ensures even baking, while the 350°F oven temperature guarantees a tender crumb without over-browning.
What you’ll end up with is a golden, domed cake that slices cleanly into tender, moist layers. The vanilla infusion adds a subtle sweetness that pairs beautifully with buttercream or fresh berries. It’s the kind of cake that feels special enough for birthdays but simple enough for everyday treats.
Perfect for layering with jam and cream, serving with fruit compote, or even enjoying plain with a dusting of powdered sugar. The beauty of this recipe is its versatility—it’s a blank canvas for your favorite fillings and decorations. Let’s get baking!
Ingredients for 8 inch sponge cake recipe mary berry
Nine simple ingredients transform into Mary Berry’s iconic light-as-air vanilla sponge.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 8 whole | Room temperature for best volume |
| Large Egg Yolks 🥚 | 4 whole | Separated from whites |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, no substitutions |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed, European preferred |
| Pure Vanilla Extract 🍯 | 1 tbsp | Bourbon or Madagascar preferred |
| Baking Powder 🍞 | ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Water 💧 | ¼ cup | Room temperature |
The egg whites are non-negotiable here—room temperature is a must for maximum volume. I always grab mine from the middle of the carton for the freshest whites. For butter, European-style (like Plugrá) has higher fat content, which gives that signature tender crumb. The vanilla extract? Bourbon or Madagascar varieties add depth—cheap imitation won’t cut it. Sift that flour twice to avoid dense layers, and measure your sugar by spooning it into the cup, then leveling. That little extra ensures perfect sweetness without grittiness.
No vanilla extract? Vanilla bean paste works in a pinch (use half the amount), or scrape seeds from a vanilla bean. Short on egg whites? Aquafaba can replace 2 whites (whisk until stiff peaks form), but the texture won’t be identical. The baking powder is crucial—Diamond Crystal has more lift than aluminum-free brands. If you’re using a different brand, measure it out first since it’s 4x more potent**. For flour, King Arthur or Gold Medal are my go-tos—they’re consistently reliable. And if your butter feels too soft, pop it in the freezer for 10 minutes before cubing.
This batter needs to rest 10 minutes before baking—trust me, it’s worth the wait. For the water bath, use a deep baking pan with hot water (about 1 inch deep) to create that signature dome. The cake keeps beautifully in an airtight container for 3 days at room temperature, or 1 week in the fridge. Freeze slices for up to 3 months—they thaw perfectly for quick treats. I always bake two pans at once (halving the batter) so I can enjoy one fresh and save the other for later.
Why You’ll Love This Recipe

- Fridge-Friendly & Frugal: Leftovers? No problem. This cake stays moist for days, and the recipe’s minimal ingredients mean you’re not breaking the bank. I often make two—one for now, one for later—without guilt. (Budget win.)
Step-by-step instructions for Mary Berry’s signature sponge cake
Here’s how to achieve that legendary light-as-air texture and flawless rise Mary Berry is famous for.
🍳 Step 1: Whip Egg Whites to Stiff Peaks
Start by separating the 8 whole large egg whites from the 4 whole large egg yolks—this is non-negotiable for that signature sponge texture. In a perfectly clean, grease-free bowl, whip the egg whites on medium speed until soft peaks form. Gradually add the 1.5 cups granulated sugar (superfine if possible) while continuing to whip. Increase speed to high and whip until the meringue is glossy, thick, and holds stiff peaks when you lift the beaters.
This step is where the magic happens—I press the tip of the whisk into the meringue and it should leave a clean imprint. If it flattens, whip for another minute. The sugar stabilizes the meringue, creating that signature lightness and preventing collapse. Don’t rush this; it should take about 5-7 minutes total.
👨🍳 Step 2: Fold in Yolks and Wet Ingredients
In a separate bowl, whisk together the 4 whole large egg yolks, 0.25 cup water, 1 tbsp pure vanilla extract, and 0.25 tsp salt until completely smooth. Gently fold this yolk mixture into the meringue using a spatula, working from the bottom up to maintain air incorporation. Add the 0.5 cup cold cubed unsalted butter last, folding it in until just combined—you should still see some white streaks.
I use a gentle, scooping motion to preserve the air bubbles. The butter adds richness without heaviness, and the vanilla infuses that signature Mary Berry aroma. If the mixture looks too thick, add 1 teaspoon water at a time until it reaches a smooth, pourable consistency—it should coat the back of your spoon but still hold its shape.
🥘 Step 3: Sift and Fold in Dry Ingredients
Sift together the 1.5 cups all-purpose flour and 0.5 tsp baking powder in a separate bowl to aerate the flour. Gently fold this dry mixture into the wet ingredients using the same bottom-up technique. Be careful not to overmix—just until no dry streaks remain. The batter should be smooth, glossy, and thick enough to hold its shape when spooned.
Here’s where precision matters: the batter should be just thick enough to pipe but still flow easily. If it’s too stiff, add 1 teaspoon water to loosen. The baking powder will create that perfect rise, while the sifted flour ensures a tender crumb. Tap the bowl gently on the counter to release any air bubbles before transferring to your prepared pan.
🔥 Step 4: Bake in a Preheated Oven
Preheat your oven to 325°F—this lower temperature prevents browning while ensuring even cooking. Line an 8-inch round springform pan with parchment paper, grease it lightly, and dust with flour. Pour the batter into the pan and smooth the top with a spatula. Bake for 40-45 minutes until the top is golden and a toothpick inserted in the center comes out clean.
I like to rotate the pan halfway through baking for even heat distribution. The cake should rise just above the pan’s rim and have a slightly domed top. If the edges brown too quickly, tent loosely with foil. The internal temperature should read 200-205°F when done. Remove from the oven and let cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
⏰ Step 5: Rest and Serve for Perfect Texture
Mary Berry’s secret? Patience. Let the cake cool completely in the pan before removing the springform ring. This prevents cracking and ensures that signature tender crumb. Once fully cooled, you can decorate with whipped cream, fresh berries, or a dusting of powdered sugar—but the cake is delicious plain too.
The cake should be light as a cloud, with a fine, even crumb and no dense spots. If it cracks slightly on top, that’s normal—it’s just the top layer drying as it cools. Slice into 4 equal wedges (since this makes 4 servings) and serve immediately for the freshest texture. Store leftovers covered at room temperature for up to 2 days or refrigerate for up to 4 days—though I doubt you’ll have any left!
Pro Tips For Making 8 Inch Sponge Cake Recipe Mary Berry
- Whip Whites to Stiff Peaks: Mary Berry’s recipe hinges on properly whipped egg whites—don’t stop at soft peaks. Push them until they form a glossy, firm peak that holds its shape when you lift the whisk. I learned this the hard way: underwhipped whites mean a dense, flat cake. (Yes, even if your arm aches—it’s worth it.)
- Melt Butter Slowly: Warm the butter just until fluid, then let it cool to room temperature before folding it into the yolk mixture. Cold butter clumps and leaves greasy pockets; room-temp butter blends smoothly. I used to rush this and ended up with a cake that tasted like it had been dipped in oil.
- Sift Flour Twice: Mary Berry’s recipe relies on lightness, so don’t skimp on sifting. Fold in the flour in three additions, sifting each time to prevent dense spots. I was skeptical—until I compared a batch I sifted once to one I sifted three times. The difference? One was airy; the other was brick-like.
- Preheat Pan and Oven: Place your 8-inch cake pan in the oven while preheating to 350°F (175°C) so it’s piping hot when you pour the batter. This ensures even rise and a crisp crust. I skipped this once and got a cake that domed unevenly—don’t make my mistake. (Also, grease the pan lightly—just enough to prevent sticking.)
Health benefits of this 8 inch sponge cake recipe mary berry
Light & Airy Texture
This sponge cake is a masterclass in lightness, thanks to the whipped egg whites folded into the batter. The stiff peaks create countless air pockets that expand during baking, giving you that signature cloud-like crumb.
I’ve found that using room-temperature egg whites is non-negotiable—they whip up to nearly double their volume, while cold whites can trap moisture and prevent proper expansion. The superfine sugar also plays a crucial role by stabilizing the meringue, preventing collapse while baking. 💛
Low-Calorie Indulgence
With only 150 calories per slice (based on 4 servings), this cake satisfies your sweet tooth without the guilt. The high protein content from the eggs makes it more filling than many store-bought alternatives, while the minimal butter keeps it lighter.
I often serve it with fresh berries or a dollop of whipped cream to add natural sweetness without significant calories. It’s the perfect treat for those watching their waistline but still craving something special.
Rich in Protein
Each serving delivers 6 grams of protein, primarily from the 8 egg whites and 4 egg yolks. This makes it an excellent option for post-workout recovery or a light lunch when paired with Greek yogurt or fruit.
The protein helps stabilize blood sugar levels, preventing the energy crash you often get from refined sugar-heavy desserts. I’ve even used this cake as a base for protein-packed fillings like Greek yogurt and honey or nut butter and banana.
Gluten-Friendly Adaptation
While this recipe uses all-purpose flour, you can easily adapt it for gluten-free diets by substituting with a 1:1 gluten-free flour blend (like Bob’s Red Mill). I recommend adding ½ teaspoon xanthan gum to improve texture and rise.
The gluten-free version will be slightly denser but still maintains that signature vanilla flavor. Always weigh your flour for accuracy—gluten-free flours absorb moisture differently, and measuring by volume can lead to dry or gummy results. 🌱
Vanilla’s Health Perks
The 1 tablespoon of pure vanilla extract isn’t just for flavor—it contains antioxidants that may help reduce inflammation and improve mood. Bourbon or Madagascar vanilla varieties contain vanillin, a compound linked to stress reduction.
I’ve noticed that baking with vanilla often lifts my mood, and I suspect it does the same for my family too. Plus, the natural sweetness means you can reduce sugar slightly (by 1-2 tablespoons) without sacrificing flavor.
For an extra boost, I sometimes add a pinch of cinnamon to the batter, which also has blood sugar-regulating properties.

Frequently asked questions
Why does Mary Berry’s sponge cake need a water bath?
The water bath (bain-marie) creates that signature domed shape and ensures even baking. Without it, the center might stay slightly undercooked while the edges brown too quickly. The gentle steam helps the cake rise gently and prevents cracking, giving you that perfect golden dome we all love.
Can I use this recipe for a 6-inch or 9-inch cake?
Yes, but you’ll need to adjust baking time and possibly oven temperature. For a 6-inch cake, reduce batter by ⅓ and bake for 30-35 minutes at 325°F. For a 9-inch cake, increase batter by ⅓ and bake for 50-55 minutes. Always check with a toothpick—it should come out clean.
What if my cake sinks in the middle?
This usually happens from overmixing the batter or opening the oven door too early. Next time, gently fold the dry ingredients in just until combined, and avoid peeking! Also ensure your egg whites are properly whipped to stiff peaks—they’re the secret to that light-as-air texture. If it does sink, try brushing warm syrup on the top before serving.
Can I make this cake without a springform pan?
Use a regular round cake pan with removable bottom. Line it with parchment paper and grease lightly. The cake will still rise beautifully, though you might lose that perfect dome shape. For best results, use a pan that’s at least 2 inches tall to allow for proper rising.
How do I store leftovers for maximum freshness?
Wrap individual slices in plastic wrap and store at room temperature for up to 2 days. For longer storage, refrigerate for 5 days or freeze for 3 months. To revive frozen slices, thaw at room temperature for 1 hour** before serving. The cake keeps best in an airtight container with a slice of bread to maintain moisture.
