Genoise is a classic Italian sponge cake known for its light, airy texture and rich flavor. Using just eggs, sugar, and a little flour, this 7-egg genoise recipe produces a versatile base perfect for layered cakes, roulades, or standalone treats. Its simplicity and reliability make it a favorite among bakers looking for a tender, moist sponge with a delicate crumb.
Ingredients
- 7 large eggs
- 200 grams (1 cup) granulated sugar
- 125 grams (1 cup) all-purpose flour, sifted
- 30 grams (2 tablespoons) unsalted butter, melted (optional, for greasing)
- Pinch of salt
Instructions
- Prepare your equipment: Grease and line the bottom of an 8-inch (20 cm) round cake pan with parchment paper. Preheat your oven to 350°F (175°C).
- Separate the eggs: Carefully separate the eggs, placing yolks and whites in separate bowls. Make sure no yolk contaminates the whites to ensure maximum volume when beating.
- Whisk the egg yolks and sugar: In a large heatproof bowl, combine the egg yolks and 100 grams of sugar. Place the bowl over a pot of simmering water (double boiler) and whisk constantly until the mixture is warm and slightly thickened, about 3-4 minutes. Remove from heat and continue whisking until the mixture cools and becomes pale and fluffy.
- Whip the egg whites: In a clean, dry bowl, beat the egg whites with a pinch of salt using an electric mixer on high speed. Gradually add the remaining 100 grams of sugar and beat until stiff, glossy peaks form.
- Combine yolk mixture with whites: Gently fold the whipped egg yolk mixture into the beaten egg whites in three additions. Use a spatula and a gentle folding motion to preserve the airiness.
- Incorporate the flour: Sift the flour over the batter in three parts. Carefully fold in each addition just until combined, being cautious not to deflate the batter.
- Add melted butter (optional): If desired, gently fold in the melted butter for added richness, but this step is optional and 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 a toothpick inserted in the center comes out clean. Do not open the oven door during the first 20 minutes to prevent collapse.
- Cool and unmold: Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, run a knife around the edges and invert onto a wire rack to cool completely before frosting or serving.
Tips
- Egg temperature: Use eggs at room temperature for better volume and easier whipping.
- Folding technique: Be gentle when folding in the flour and whites to maintain the batter’s airy structure, which is crucial for a light genoise.
- Substitutions: You can substitute all-purpose flour with cake flour for an even softer crumb. For a dairy-free version, omit the butter or replace it with a neutral oil.
- Storage: Keep the cooled genoise wrapped tightly in plastic wrap at room temperature for up to 2 days or refrigerated for up to 4 days. To prevent it from drying out, avoid prolonged exposure to air.
- Common mistake: Overmixing after adding flour can deflate the batter. Fold gently and stop as soon as the flour disappears.
Serving Suggestions
This versatile genoise serves beautifully as a layer cake filled with pastry cream, fruit preserves, or whipped cream. It can also be sliced and used as a base for trifles, tiramisu, or semifreddo. Dust the top with powdered sugar or cocoa powder for an elegant presentation.
Variations
For different flavors, incorporate additions such as lemon zest, vanilla extract, or almond extract into the batter. You can also infuse the batter with a splash of liqueur like Grand Marnier or Amaretto for a more sophisticated taste. To make a chocolate genoise, fold in melted, cooled chocolate at the flour stage.
Storage and Reheating
Genoise can be stored at room temperature, wrapped tightly in plastic wrap, for up to 2 days. For longer storage, refrigerate for up to 4 days. If the cake has dried out, briefly warm slices in a low oven (around 300°F/150°C) for 5-10 minutes to refresh its moisture. Avoid freezing unless properly wrapped, as moisture loss can affect texture.
Frequently Asked Questions
Can I make genoise ahead of time?
Yes, you can prepare the cake one or two days in advance. Wrap it tightly in plastic wrap and store at room temperature or in the refrigerator. To keep it fresh, consider brushing it lightly with a flavored syrup before assembling or serving.
Why did my genoise turn out dense or flat?
This often happens if the eggs weren’t whipped enough, if the batter was overmixed after adding flour, or if the oven temperature was too low. Ensuring proper whipping and gentle folding helps maintain the cake’s lightness.
Can I use a different pan size?
Yes, but adjust the baking time accordingly. A larger or shallower pan will bake quicker, while a smaller or deeper pan may need additional time. Always check doneness with a toothpick or cake tester.
Is it necessary to sift the flour?
Sifting the flour helps prevent lumps and ensures even incorporation, which is vital for a smooth, airy batter. It also helps the flour blend more easily with the whipped eggs.
What is the best way to fold ingredients without deflating the batter?
Use a gentle, sweeping motion with a spatula, lifting from the bottom and folding over the batter’s surface. Turn the bowl as you go to ensure even mixing without losing the air created during whipping.
Can I make this vegan or gluten-free?
For a vegan version, replace eggs with aquafaba or commercial egg replacers, and use a plant-based butter or oil. For gluten-free, substitute all-purpose flour with a gluten-free baking blend, but be aware that texture may vary slightly.
