Ingredients
- 6 large eggs, at room temperature
- 150 grams (3/4 cup) granulated sugar
- 150 grams (1 1/4 cups) 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 oven and pan: Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan and line the bottom with parchment paper to prevent sticking. Set aside.
- Beat 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 doesn’t 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 for about 8-10 minutes until the mixture triples in volume, becomes pale, and forms thick ribbons when the beaters are lifted.
- Incorporate the flour: Sift the flour over the egg mixture in three additions. Gently fold each addition in using a spatula, working carefully to maintain the volume. Be gentle to avoid deflating the batter.
- Add melted butter and vanilla: If using, gently fold in the melted butter and vanilla extract until just combined. This adds moisture and flavor but is optional.
- Pour into the pan: Transfer the batter into your prepared cake pan, smoothing the top with a spatula.
- Bake: Bake in the preheated oven for 25-30 minutes, or until the cake springs back when lightly pressed and a toothpick inserted in the center comes out clean.
- Cool: Remove from oven and let the cake cool in the pan for 10 minutes. Then, turn out onto a wire rack to cool completely before using or frosting.
Tips
- Egg temperature matters: Use eggs at room temperature for better volume and easier incorporation into the batter.
- Sifting flour: Always sift the flour to prevent lumps and ensure a light, airy texture.
- Folding technique: When adding flour and butter, fold gently to preserve the air bubbles that give the genoise its lift.
- Avoid overmixing: Overmixing can deflate the batter, resulting in a denser cake. Mix just until ingredients are combined.
- Storage: Keep the cooled genoise in an airtight container for up to 2 days at room temperature, or freeze for longer storage.
Serving Suggestions
This genoise serves as a perfect base for layered cakes, such as sponge cakes filled with fruit preserves, pastry cream, or whipped cream. It can also be sliced and served plain with a dusting of powdered sugar, or used as a component in trifles and charlottes. For a more decadent presentation, frost with buttercream, ganache, or whipped mascarpone.
Variations
To customize your genoise, consider adding citrus zest (lemon or orange) to the batter for a fresh flavor. You can also incorporate cocoa powder into the flour for a chocolate genoise, or fold in chopped nuts or dried fruits for added texture. For a richer cake, substitute part of the flour with ground almonds or hazelnuts.
Storage and Reheating
Store the cooled genoise wrapped tightly in plastic wrap or in an airtight container at room temperature for up to 2 days. For longer storage, freeze the cake wrapped in plastic wrap and foil for up to 1 month. To thaw, leave at room temperature for about 2 hours. Reheating isn’t necessary, but if you wish to warm slices, do so briefly in a low oven or microwave for a few seconds.
Frequently Asked Questions
Can I make genoise ahead of time?
Yes, you can bake the genoise a day in advance. Store it properly wrapped at room temperature or in the fridge if your environment is humid. Before using, let it come to room temperature, and if desired, lightly dust with powdered sugar or re-frost as needed.
What if my batter deflates after mixing?
This usually happens if the batter is overmixed or if the eggs weren’t properly whipped. To prevent this, fold ingredients gently and ensure your eggs are beaten until very fluffy and voluminous. Also, avoid opening the oven door during baking.
Can I substitute gluten-free flour?
Yes, but use a gluten-free flour blend designed for baking, preferably one with xanthan gum included. The texture may vary slightly, so you might need to adjust the amount of flour or add a binding agent.
How do I know when the cake is done?
Insert a toothpick into the center of the cake; if it comes out clean or with just a few moist crumbs, the cake is ready. The top should be golden and spring back when lightly pressed.
Why is my genoise dry or dense?
This can result from overbaking, not beating the eggs enough, or overmixing after adding the flour. Ensure proper beating of eggs and sugar, and bake just until golden and a toothpick tests clean.
