This classic sponge forms the perfect base for elegant layered cakes and desserts. Its light, airy texture comes from a precise technique that ensures a tender crumb every time.
With just a few simple ingredients and careful folding, you’ll achieve a light and delicate foundation that pairs beautifully with fillings and frostings.
Ingredients for Mary Berry Genoise Sponge
A handful of precise ingredients create this delicate, airy foundation for layered desserts.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 4 whole | Room temperature, separated |
| Granulated Sugar 🍚 | ¾ cup | Superfine for best texture |
| All-Purpose Flour 🌾 | ¾ cup | Sifted for airiness |
| Unsalted Butter 🧈 | ¼ cup | Melted and cooled |
| Pure Vanilla Extract 🌿 | 1 tsp | High-quality for flavor |
| Salt 🧂 | 0.125 tsp | Fine sea salt preferred |
| Lemon Zest 🍋 | 1 tsp | Optional for brightness |
| Cold Water 💧 | 2 tbsp | For stabilizing the batter |
The eggs are critical here—room temperature ensures maximum volume when whipped. I recommend organic, free-range eggs for superior structure and color. Superfine sugar dissolves more efficiently, but standard granulated works if pulsed briefly in a food processor. King Arthur Flour is my go-to for consistent results in delicate sponges like this.
No superfine sugar? Pulse regular granulated in a food processor for 30 seconds. Out of vanilla extract? Vanilla bean paste adds speckles and intensity. For a citrus variation, orange zest at the same amount works beautifully. The butter must be completely cooled before folding in to prevent deflating the batter.
This batter is best used immediately—it loses volume quickly. Store the baked sponge wrapped tightly in plastic at room temperature for up to 2 days, or freeze for 1 month. Thaw at room temperature before using.

Step-by-Step Instructions for Genoise Sponge
Master this classic technique for a light, airy sponge that forms the foundation of many elegant desserts.
Step 1: Whip the Eggs and Sugar to Ribbon Stage
In a heatproof bowl, combine the 4 whole Large Eggs and 0.75 cup Granulated Sugar. Place the bowl over a saucepan of simmering water, ensuring the bottom doesn’t touch the water. Whisk constantly for 3-4 minutes until the mixture reaches 110°F on an instant-read thermometer.
Immediately transfer the bowl to a stand mixer fitted with the whisk attachment. Beat on high speed for 5-7 minutes until the mixture triples in volume, turns pale yellow, and forms thick ribbons that hold their shape for 5 seconds when the whisk is lifted. This stage is critical for achieving the sponge’s signature lightness.
Step 2: Fold in the Dry Ingredients
Sift the 0.75 cup All-Purpose Flour and 0.125 tsp Salt together. With the mixer on low speed, add about one-third of the flour mixture to the egg mixture. Once incorporated, stop the mixer and gently fold in the remaining flour by hand using a silicone spatula.
Fold just until no streaks of flour remain—overmixing will deflate the batter. The goal is to maintain as much air as possible while ensuring even distribution of the flour. Work quickly but carefully to preserve the volume achieved in the previous step.
Step 3: Incorporate the Melted Butter and Flavorings
In a small bowl, combine the 0.25 cup Unsalted Butter (melted and cooled), 1 tsp Pure Vanilla Extract, 1 tsp Lemon Zest, and 2 tbsp Cold Water. Gently fold this mixture into the batter in two additions, ensuring each is fully incorporated before adding the next.
The melted butter adds richness and structure, while the vanilla and lemon zest provide depth of flavor. The cold water helps stabilize the batter, preventing the butter from causing deflation. The final batter should be smooth, glossy, and light enough to leave a faint trail when the spatula is lifted.
Step 4: Bake Evenly for a Perfect Rise
Pour the batter into an ungreased 9-inch round cake pan lined with parchment paper on the bottom. Smooth the top gently with the spatula, avoiding any pressing that might remove air. Bake in a preheated 350°F oven for 25-30 minutes, or until the top springs back when lightly pressed and a toothpick inserted into the center comes out clean.
Avoid opening the oven door during the first 20 minutes to prevent the sponge from collapsing. The cake should rise evenly with a slightly domed top and pull away slightly from the sides of the pan. The edges should be golden brown, while the center remains pale.
Step 5: Cool Properly to Preserve Texture
Remove the cake from the oven and let it cool in the pan for 10 minutes. This brief rest allows the structure to set slightly, reducing the risk of collapse. After 10 minutes, run a thin knife around the edge to loosen, then invert the cake onto a wire rack lined with parchment paper.
Peel off the parchment from the bottom and let the sponge cool completely on the rack. Proper cooling is essential to maintain the airy texture. Once fully cooled, the genoise is ready to be filled, frosted, or layered as desired in your dessert creation.
Pro Tips For Making Mary Berry Genoise Sponge
- Warm the Eggs: Take your eggs out of the fridge 30 minutes before starting—room temperature eggs whip up to triple their volume, which is non-negotiable for that light genoise texture.
- Fold Gently: When adding flour, use a spatula and fold in a J-shape motion. I learned this the hard way—overmixing deflates the batter and turns your sponge dense.
- Melt the Butter: Cool your melted butter slightly before mixing it in, but don’t let it solidify. Hot butter can cook the eggs, while cold butter will clump—both ruin the smooth batter.
- Skip the Grease: Sounds weird, but it works: don’t grease your cake tin. A clean, ungreased surface helps the genoise climb and hold its shape as it bakes.
Flavor Customization for This Dish
Citrus Variations
Swap the 1 tsp Lemon Zest for lime or orange zest to create a bright, zesty twist. I love how orange zest adds a warm, floral note that pairs beautifully with chocolate fillings. 🍊
Spiced Infusions
Add ½ tsp ground cinnamon or ¼ tsp cardamom with the flour for a warm, aromatic touch. These spices complement fruit fillings like berries or poached pears wonderfully.
Chocolate Genoise
Replace 2 tbsp of the All-Purpose Flour with 2 tbsp unsweetened cocoa powder for a subtle chocolate flavor. This version works perfectly with chocolate ganache or mocha buttercream fillings. 💫
Almond Flour Boost
Substitute ¼ cup of the All-Purpose Flour with ¼ cup finely ground almond flour for a nutty depth. This adds richness and pairs well with raspberry or almond cream fillings.
Coffee Lovers
Dissolve 1 tsp instant espresso powder in the 2 tbsp Cold Water before adding to the batter. The coffee enhances the vanilla and adds complexity, ideal for tiramisu-style desserts.
Herbal Notes
Infuse the 0.25 cup Unsalted Butter with 1 sprig fresh rosemary or 2 sprigs thyme while melting. Strain before using. This subtle earthiness works surprisingly well with citrus curds.

Frequently Asked Questions
What makes a genoise sponge different from other sponges?
It relies on whipped whole eggs and sugar for leavening instead of baking powder. This creates a lighter, more delicate texture that absorbs syrups and fillings beautifully.
Why do my eggs need to be room temperature?
Room temperature eggs whip up to greater volume, creating more air bubbles for that signature light texture. Cold eggs won’t expand as much, resulting in a denser sponge.
Can I make this ahead of time?
Yes! Wrap the cooled sponge tightly in plastic and store at room temperature for up to 2 days. It can also be frozen for 1 month if properly wrapped.
What’s the most common mistake to avoid?
Overmixing after adding flour. This deflates the air bubbles you worked so hard to create. Fold just until the flour disappears.
