Genoise is a classic Italian sponge cake known for its delicate texture and rich flavor. Using just nine eggs, this recipe creates a tall, airy cake perfect for layering and decorating. Its simplicity and reliable rise make it a favorite among bakers looking to master the art of sponge cakes.
Ingredients
- 9 large eggs, at room temperature
- 1 cup (200 g) granulated sugar
- 1 teaspoon pure vanilla extract (optional)
- 1 cup (125 g) all-purpose flour, sifted
- 1/4 cup (30 g) cornstarch or potato starch (optional, for extra tenderness)
- Pinch of salt
- Powdered sugar for dusting (optional)
Instructions
- Preheat your oven to 350°F (175°C). Grease an 8-inch (20 cm) round cake pan and line the bottom with parchment paper to prevent sticking.
- In a large mixing bowl, combine the eggs and sugar. Using an electric mixer, beat on high speed for about 8-10 minutes until the mixture is thick, pale, and tripled in volume. The batter should fall in thick ribbons when the beaters are lifted.
- Gently fold in vanilla extract if using. Sift together the flour, cornstarch (if using), and salt. Sift the dry ingredients over the egg mixture in thirds, carefully folding each addition in with a spatula. Use a gentle motion to maintain the airy structure of the batter.
- Pour the batter into the prepared cake pan, smoothing the top with a spatula. Tap the pan gently on the counter to release any large air bubbles.
- Bake in the preheated oven for 30-35 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean.
- Remove from oven and let the cake cool in the pan for about 10 minutes. Then, turn out onto a wire rack and cool completely before handling or decorating.
Tips
- Eggs at room temperature: They whip better and help achieve maximum volume. To warm eggs quickly, place them in warm water for 5 minutes.
- Folding technique: Carefully fold dry ingredients into the whipped eggs to preserve the airiness. Do not overmix, as this can deflate the batter.
- Sifting dry ingredients: Sifting helps prevent lumps and ensures an even distribution, resulting in a lighter cake.
- Storage: Keep the cake covered at room temperature for up to 2 days or refrigerate for up to 4 days. For longer storage, freeze wrapped tightly in plastic wrap and foil for up to 1 month.
Serving Suggestions
This genoise is versatile and works well as a layered cake with fresh fruit, whipped cream, or buttercream. Dust the top with powdered sugar or cocoa powder for a simple presentation. It’s perfect for birthday cakes, wedding desserts, or elegant teatime treats.
Variations
Try adding lemon or orange zest to the batter for a citrus twist. Incorporate melted chocolate into the batter for a chocolate genoise. You can also infuse the batter with coffee or liqueurs to add depth of flavor. For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend.
Storage and Reheating
Store the cooled cake in an airtight container at room temperature for up to 2 days. For longer storage, wrap tightly and refrigerate for up to 4 days or freeze for up to 1 month. To reheat, let the cake come to room temperature if refrigerated, or warm slices gently in a low oven (around 300°F/150°C) for 5-10 minutes. Avoid microwaving for long to prevent drying out.
Frequently Asked Questions
Can I make genoise ahead of time?
Yes, you can bake the cake a day in advance. Store it properly wrapped or in an airtight container at room temperature or refrigerated. This allows the flavors to meld and the texture to settle, making it even easier to assemble your layered desserts.
Why did my genoise turn out flat or dense?
Common reasons include under-whipping the eggs, overfolding the dry ingredients, or opening the oven door during baking. Ensure your eggs are whipped to stiff peaks and fold gently. Maintaining the oven temperature is crucial for proper rise.
Can I substitute the eggs with egg replacers?
While traditional genoise relies on the eggs’ structure, some commercial egg replacers or aquafaba (chickpea brine) can be used, but the texture may differ. For best results, use fresh, large eggs and whip them thoroughly.
Is genoise suitable for people with gluten intolerance?
Standard genoise contains gluten from wheat flour. To make it gluten-free, substitute the all-purpose flour with a gluten-free flour blend, but note that the texture might vary slightly. Be sure to test and adjust the recipe accordingly.
How do I prevent my genoise from sinking in the middle?
Ensure the batter is fully cooked by testing with a toothpick. Avoid opening the oven door during baking and do not overmix the batter once the dry ingredients are added. Proper folding and accurate baking time help prevent sinking.
