A classic genoise is a versatile, airy sponge cake that forms the perfect base for layered desserts, tarts, or simply enjoyed on its own. Made with just four eggs and a few simple ingredients, this recipe yields a light, tender crumb that holds together beautifully. Perfect for bakers of all skill levels, it’s a reliable choice for creating elegant cakes with a delicate texture that impresses every time.
Ingredients
- 4 large eggs, at room temperature
- 150 grams (3/4 cup) granulated sugar
- 120 grams (1 cup) all-purpose flour, sifted
- 30 grams (2 tablespoons) unsalted butter, melted and cooled (optional for added richness)
- 1 teaspoon vanilla extract (optional)
Instructions
- Prepare your equipment: Preheat your oven to 350°F (180°C). Grease a 9-inch (23cm) round cake pan and line the bottom with parchment paper. Have your sifted flour and melted butter ready.
- Whisk the eggs and sugar: In a large heatproof mixing bowl, combine the eggs and sugar. Place the bowl over a pot of simmering water (double boiler method). Whisk constantly until the mixture is warm to the touch and slightly thickened, about 3-4 minutes. Remove from heat.
- Whip the egg mixture: Using an electric mixer on high speed, beat the egg mixture until it triples in volume, becomes pale, and forms thick ribbons when the beaters are lifted. This step takes about 8-10 minutes. Proper aeration is key to a light genoise.
- Gently fold in the flour: Sift the flour over the whipped eggs in three additions. Use a silicone spatula to gently fold each addition in, being careful not to deflate the batter. Fold until just combined.
- Add melted butter and vanilla: If using, gently fold in the cooled melted butter and vanilla extract in small portions, just until incorporated. This adds richness but can be omitted for a lighter cake.
- Bake the cake: Pour the batter into the prepared pan, smoothing the top. Bake in the preheated oven for 25-30 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean.
- Cool and unmold: Let the cake cool in the pan for about 10 minutes. Then, run a knife around the edges, turn out onto a wire rack, and peel off the parchment paper. Allow to cool completely before slicing or decorating.
Tips
- Eggs at room temperature: Using eggs at room temperature helps achieve better volume. If your eggs are cold, gently warm them in a bowl of warm water for a few minutes.
- Sifting flour: Always sift the flour to prevent lumps and ensure a light, airy texture in your genoise.
- Folding technique: Be gentle when folding in the flour and butter to maintain the airiness of the whipped eggs. Overmixing can deflate the batter.
- Storage: Keep the cooled genoise wrapped in plastic wrap at room temperature for up to 2 days. For longer storage, refrigerate for up to 3 days or freeze for up to 1 month.
- Adding flavor: You can infuse the batter with lemon zest, almond extract, or other flavorings for variation.
Serving Suggestions
This genoise is perfect as a base for layered cakes like sponge cakes with fruit and cream, or used as a component in more elaborate desserts such as trifles or charlottes. Dust with powdered sugar, spread with jam, or layer with pastry cream and fresh fruit for a stunning presentation. It also pairs beautifully with whipped cream and berries for a light, summery treat.
Variations
- Chocolate Genoise: Fold in 2 tablespoons of cocoa powder with the flour for a rich chocolate version.
- Lemon-Infused Genoise: Add 1 teaspoon of lemon zest to the batter and replace vanilla with lemon extract for a citrus twist.
- Nutty Genoise: Incorporate finely chopped toasted almonds or hazelnuts into the batter for added texture and flavor.
- Vegan Genoise: Use aquafaba (chickpea brine) whipped to stiff peaks instead of eggs, and replace butter with a neutral oil or vegan butter.
Storage and Reheating
Store the cooled genoise tightly wrapped in plastic wrap at room temperature for up to 2 days. For longer storage, refrigerate in an airtight container for up to 3 days or freeze for up to 1 month. To reheat, briefly warm in a low-temperature oven (around 300°F/150°C) for 10-15 minutes if desired, but generally, it’s best served at room temperature or slightly chilled for optimal texture.
Frequently Asked Questions
Can I make genoise ahead of time?
Yes, you can prepare the genoise a day in advance. Wrap it tightly in plastic wrap and store at room temperature or refrigerate. It’s best to assemble or decorate just before serving to maintain freshness.
Why did my genoise turn out dense or rubbery?
This typically happens if the eggs were not whipped enough to incorporate sufficient air or if the batter was overmixed after folding in the flour. Proper whipping and gentle folding are essential for a light texture.
Can I use gluten-free flour?
Gluten-free flours can be used, but they may alter the texture. For best results, use a blend designed for baking or add a small amount of xanthan gum to mimic gluten’s elasticity. Expect slightly denser results.
How can I prevent the cake from sticking to the pan?
Make sure to properly grease and line your pan with parchment paper. Tap the pan on the counter to release air bubbles before baking, and allow the cake to cool slightly before removing from the pan to prevent tearing.
Is it necessary to melt the butter?
Melting the butter is optional but recommended if you want to incorporate it smoothly into the batter. It also helps add richness without deflating the whipped eggs, but you can omit it for a lighter, more delicate cake.
