Genoise is a classic Italian sponge cake known for its light, airy texture and rich flavor. Made with eggs, sugar, and a touch of flour, it relies on proper technique to achieve its signature rise and tenderness. This 10-egg genoise recipe produces a perfect base for layered cakes, tiramisu, or simply enjoyed on its own with a dusting of powdered sugar.
Ingredients
- 10 large eggs, at room temperature
- 1 cup (200g) granulated sugar
- 1 teaspoon pure vanilla extract (optional)
- 1 cup (125g) all-purpose flour, sifted
- 1/4 teaspoon salt
- 2 tablespoons unsalted butter, melted (optional, for greasing)
Instructions
- Preheat your oven to 350°F (175°C). Grease an 8-inch (20cm) round cake pan and line the bottom with parchment paper. Alternatively, you can use a springform pan for easier removal.
- Prepare 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) ensuring the bottom does not touch the water. Whisk constantly until the mixture is warm to the touch and slightly thickened, about 3-4 minutes.
- Whisk until fluffy: Remove from heat and using an electric mixer, beat on high speed until the mixture triples in volume, becomes pale, and forms a thick, ribbon-like consistency. This can take 8-10 minutes. Add vanilla extract during the last minute if desired.
- Incorporate the flour: Sift the flour and salt together. Gently fold the dry ingredients into the egg mixture in three additions, using a spatula. Be careful not to deflate the batter.
- Finish the batter: If using, gently fold in the melted butter to add richness, but this step is optional as traditional genoise is often made without fat.
- Pour into the pan: Transfer the batter into the prepared pan, smoothing the top with a spatula. Tap the pan gently on the counter to remove air bubbles.
- Bake: Place in the preheated oven and bake for 25-30 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean.
- Cool: Let the cake cool in the pan for 10 minutes, then run a knife around the edges and invert onto a wire rack. Remove the parchment paper and allow to cool completely before frosting or slicing.
Tips
- Egg temperature matters: Use eggs at room temperature for better volume and easier mixing.
- Do not overmix: When folding in the flour, be gentle to maintain the airiness of the batter.
- Use fresh eggs: Fresh eggs whip better and give a better rise.
- Storage: Keep the genoise in an airtight container at room temperature for up to 2 days or refrigerate for up to 3 days. To freeze, wrap tightly in plastic wrap and store for up to 1 month.
Serving Suggestions
This light sponge cake pairs beautifully with fresh berries, whipped cream, or fruit compotes. It also serves as a perfect base for layered cakes like tiramisu or mousse cakes, where its airy texture absorbs flavors well.
Variations
For a flavored genoise, add citrus zest (lemon or orange) to the egg mixture before whipping. You can also incorporate a splash of liqueur like Grand Marnier or Amaretto into the batter for added depth. Gluten-free versions can be made using almond flour, but expect a denser texture.
Storage and Reheating
Store the cooled genoise in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 3 days, covered tightly. To reheat, gently warm slices in a low oven (around 300°F or 150°C) for 5-10 minutes or serve at room temperature. Avoid microwave reheating to prevent drying out.
Frequently Asked Questions
Can I make genoise without a stand mixer?
Yes, you can use a hand whisk and a large bowl. It will require more arm strength and time to beat the eggs and sugar until fluffy, but the process remains the same. Use a double boiler to help warm the eggs and sugar for better volume.
What is the key to getting a light and airy genoise?
The most important factors are thoroughly beating the eggs and sugar until they are pale and tripled in volume, and gently folding in the flour to maintain the air bubbles. Properly whipped eggs create the structure that gives genoise its signature lightness.
Can I adapt this recipe for a smaller cake?
Absolutely. Simply reduce the number of eggs and adjust the other ingredients proportionally. For example, for a 6-inch cake, use about 6 eggs and half the other ingredients. The baking time may also decrease slightly.
Why did my genoise turn out dense or flat?
This is often caused by under-whipping the eggs, over-folding the flour, or opening the oven door during baking. Ensure the egg mixture is whipped well, fold gently, and avoid opening the oven early to maintain the rise.
Can I add flavorings or extracts?
Yes, vanilla is common, but citrus zest, almond extract, or liqueurs can enhance the flavor. Add these to the egg mixture before whipping for even distribution.
How can I prevent the cake from sticking to the pan?
Grease the pan with butter and line the bottom with parchment paper. Lightly dust with flour or powdered sugar if desired. Proper preparation ensures easy removal and a clean appearance.
