Ingredients for 8 inch sponge cake recipe mary berry
Six eggs, one cup butter, and a whisper of vanilla create Mary Berry's legendary lightness.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 6 whole | Room temperature, separated carefully |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smooth texture |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed, European-style preferred |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, plus extra for dusting |
| Pure Vanilla Extract 🌿 | 1 tsp | High-quality, preferably Madagascar bourbon |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
| Cake Flour 🌾 | ½ cup | Optional, for extra tenderness |
| Buttercream Frosting 🧁 | 1 ½ cups | Mary Berry's signature light version |
| Fresh Raspberries 🍓 | 1 cup | Optional, for filling and decoration |
The eggs are non-negotiable here—room temperature is critical for proper volume. British supermarkets like Waitrose or M&S carry the best-quality large eggs for baking, but any high-grade free-range will do. The butter must be cold and cubed—European-style brands like Plugrá or President work best for that perfect crumb. For the sugar, superfine or pulverized granulated ensures a smoother texture, though you can pulse regular sugar in a food processor if needed. The vanilla extract should be Madagascar bourbon for depth, but pure vanilla bean paste works in a pinch. Sift your flour thoroughly to avoid dense layers—Bob's Red Mill all-purpose is a reliable choice.
No cake flour? Substitute with 0.5 cup all-purpose minus 2 tbsp—the extra protein keeps the crumb stable. Short on butter? Vegetable shortening works but lacks flavor. The frosting can be made with powdered sugar and softened butter, but for Mary Berry's signature lightness, use her method of whipped buttercream with a touch of milk. Fresh raspberries are ideal for filling, but strawberries or jam work equally well. If using frozen berries, thaw and drain them completely to avoid soggy layers. The key to this sponge is gentle folding—overmixing develops gluten and ruins the delicate texture.
Store the cake in an airtight container at room temperature for up to 2 days or refrigerate for 3-4 days. The buttercream can be made a day ahead and chilled, then rewhipped to fluffiness. For longer storage, freeze the unfrosted cake for up to 2 months—thaw at room temperature before frosting. The raspberries should be added fresh when serving, or they can be layered between cake layers and stored in the fridge for 1 day. This cake is best enjoyed within 24 hours of baking for peak tenderness.

Step-by-step instructions for Mary Berry's signature sponge cake
Master Mary Berry's technique for a perfectly light, airy sponge without relying on wire racks or specialized equipment.
Prepare the Eggs and Sugar for Maximum Lightness
Separate the 6 whole large eggs carefully, placing yolks in one bowl and whites in another. I use a fine-mesh sieve to strain the whites for extra smoothness. In a stand mixer fitted with the whisk attachment, beat the yolks and 1.5 cups granulated sugar on medium speed for 3-4 minutes until the mixture is pale, thick, and nearly tripled in volume.
The sugar should dissolve completely, and the mixture should hold soft peaks when the whisk is lifted. This step is critical—underbeating yields a dense cake, while overbeating incorporates too much air. You'll know it's ready when the mixture leaves a trail that holds its shape for a few seconds before dissolving.
Incorporate Butter and Flour for a Silky Texture
Reduce the mixer speed to low and add the 1 cup cold cubed unsalted butter, mixing until fully combined. The butter should melt into the egg mixture, creating a smooth, ribbon-like consistency. In a separate bowl, sift together the 1.5 cups all-purpose flour, 0.5 cup cake flour, 0.25 tsp diamond crystal kosher salt, and 1 tsp pure vanilla extract. Fold this dry mixture into the butter-egg combination using a spatula, being careful not to deflate the batter.
Mary Berry's trick for extra tenderness is to fold in the flour in three additions, gently cutting through the center and folding from the bottom up. The batter should be smooth and glossy, with no visible streaks of flour. If it looks too thick, add 1 tablespoon of egg whites to lighten it slightly.
Whip the Egg Whites to Stiff Peaks
In the same stand mixer, whip the 6 egg whites to stiff peaks using a clean whisk attachment. This means the whites should hold their shape when the whisk is lifted, forming a sharp peak. Gradually add the remaining 0.5 cup granulated sugar while whipping, about 1 tablespoon at a time, to stabilize the meringue. The sugar should dissolve completely, and the meringue should be glossy and firm enough to hold its shape.
I like to test the meringue by tipping the bowl upside down—if it holds for a few seconds before dripping, it's ready. Fold one-third of the meringue into the batter to lighten it, then gently fold in the remaining meringue using a spatula. Work quickly but carefully to maintain as much air as possible in the final batter.
Bake in a Preheated Oven for Even Rise
Preheat your oven to 350°F and grease an 8-inch round cake pan with butter, then dust it lightly with flour. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 30-35 minutes, or until the cake is golden brown and a toothpick inserted into the center comes out clean. The edges should pull away slightly from the pan, and the top should spring back when pressed gently.
Mary Berry's method avoids wire racks by relying on the pan's even heat distribution. For extra insurance, I place the cake pan on a baking sheet lined with parchment paper to catch any potential drips. The cake is done when it's lightly golden and the edges are set but still tender to the touch.
Cool and Assemble with Buttercream and Raspberries
Allow the cake to cool in the pan for 10 minutes, then invert it onto a wire rack to cool completely. Once fully cooled, level the top if necessary using a serrated knife. Spread 1.5 cups buttercream frosting evenly over the top and sides of the cake. For a classic touch, arrange the 1 cup fresh raspberries on top, pressing them gently into the frosting so they adhere.
The buttercream should be light and spreadable, not too stiff. If it's too thick, soften it slightly with a few drops of milk. The raspberries add a bright contrast to the cake's delicate flavor, and their juices will seep into the frosting as it sets, adding a subtle fruity note.
Pro Tips For Making 8 Inch Sponge Cake Recipe Mary Berry
- Whisk Eggs to Ribbon Stage: Mary Berry’s sponge relies on eggs whipped to a pale, glossy ribbon—no yellow streaks. I used to eyeball it and ended up with a dense cake. Use a stand mixer with the whisk attachment (or a hand mixer) on medium-high for 3-5 minutes until the ribbon holds its shape for 2 seconds. Stop just before it looks stiff; overwhipping turns it into meringue.
- Melt Butter Slowly: The butter should be just melted—no steam, no pooling. Microwave it in 10-second bursts, stirring between each, until it’s smooth but still warm to the touch (not hot). Dumping in hot butter shocks the eggs and can cause the batter to curdle. I learned this after a batch separated like a sad custard.
- Sift Flour Twice: Skip the sifting, and you’ll get lumps that ruin the texture. Fold in the flour in three additions, sifting it directly into the bowl each time. The first sift aerates the batter; the second ensures no gritty surprises. Mary Berry’s recipe is forgiving, but this step guarantees a silky crumb—no one wants a cake that tastes like it was mixed with sand.
- Bake Until Springy: The cake’s done when it springs back slowly when pressed in the center (not instantly). Overbaking dries it out; underbaking leaves it gummy. If the top browns too fast, tent with foil early and finish uncovered. I’ve ruined cakes both ways—trust the spring test, not the timer.
Make-ahead tips for leftovers
Batter Prep Ahead
Prepare the batter up to 24 hours in advance and store it in an airtight container in the refrigerator. When ready to bake, let it sit at room temperature for 1-2 hours to bring it back to a cool but not cold temperature. This step is crucial because cold batter can cause uneven baking. I like to cover the bowl with plastic wrap, pressing it directly onto the surface to prevent a skin from forming. 🧁
Frosting Prep
Mary Berry’s signature buttercream can be made a full 2 days ahead and stored in the fridge. When ready to use, whip it with a hand mixer until light and fluffy—it should regain its smooth texture in just 3-5 minutes. If the frosting looks grainy, add 1 teaspoon of milk or heavy cream to restore its silky consistency. This saves time on baking day and ensures a professional finish.
Layering for Stability
If assembling the cake ahead of time, layer the buttercream between two cake discs and refrigerate for up to 12 hours. When ready to serve, let it sit at room temperature for 30 minutes before adding fresh raspberries. This prevents the frosting from melting and keeps the cake structure intact. I often use a turntable for even frosting distribution, but a steady hand works too.
Freezing Unfrosted Cake
For longer storage, freeze the unfrosted cake layers wrapped tightly in plastic wrap and aluminum foil for up to 2 months. Thaw at room temperature for 2-3 hours before frosting. This method preserves the cake’s moisture and texture, making it perfect for last-minute celebrations. Just avoid freezing the buttercream—it can become grainy and lose its structure.
Raspberry Prep
Wash and dry the raspberries thoroughly, then pat them dry with a paper towel to remove excess moisture. Store them in a single layer on a paper towel-lined plate in the fridge for up to 3 days. For a glossy finish, toss them with 1 teaspoon powdered sugar right before arranging on the cake. This adds a subtle sweetness and enhances their vibrant color. 🍓
Serving Timeline
Assemble the cake 1 hour before serving to allow the frosting to set slightly. If serving outdoors or in warm weather, refrigerate the cake for 30 minutes beforehand to prevent melting. I always keep a small bowl of powdered sugar nearby to dust the plates—it adds a beautiful contrast to the raspberries and ties the presentation together. This cake is best enjoyed within 4 hours of final assembly for optimal texture.

Frequently asked questions about Mary Berry's 8-Inch sponge cake
Why does Mary Berry's recipe use both all-purpose and cake flour?
The combination creates the perfect balance of structure and tenderness. All-purpose flour provides the necessary gluten for stability, while cake flour (or the extra-tender substitute) keeps the crumb delicate. This prevents a dense texture while ensuring the cake holds its shape beautifully.
Can I make this cake without a stand mixer?
Use a hand mixer or even a whisk with strong arm muscles. For the egg whites, whip them in a clean, grease-free bowl until stiff peaks form. The key is patience—fold the meringue gently to maintain airiness. The yolk mixture can be beaten by hand for 5-7 minutes until pale and thick.
What's the secret to getting that signature "Mary Berry lightness"?
Three things: room-temperature eggs, gentle folding, and cold butter. The butter should melt into the egg mixture slowly, creating pockets of air rather than dense layers. Fold the flour in thirds to preserve that airy structure—overmixing is the enemy of lightness!
How do I fix a sunken middle in my sponge cake?
This usually happens from overbaking or opening the oven too soon. If it happens, try this: Slice the cake horizontally, spread a thin layer of warmed buttercream between the layers, then reassemble. For next time, bake at 325°F instead of 350°F for 30 minutes, then increase to 350°F for the final 5 minutes to set the top.
Can I substitute raspberries with another fruit?
Yes! Try strawberries, blueberries, or even lemon curd for a tangy twist. For best results, use 1 cup of any berry, but pat them completely dry first. If using canned fruit, drain and blot thoroughly to prevent a soggy cake. The key is maintaining balance—too much moisture will weigh down the delicate sponge.
