Vanilla Genoise is a sponge cake originating from Genoa, unique for its lack of leavening agents like baking soda, baking powder, or yeast. The texture and volume are achieved through the whipping process, which makes the egg proteins elastic enough to trap air. This classic recipe balances the weight of eggs with sugar and flour, making it perfect for tea time or as a base for enhancements like chocolate, nuts, or icing.

Place the eggs and sugar in a metal bowl.
Heat over a double boiler, whisking constantly, until the mixture reaches 40°C (it should feel warm to the touch).
Remove from heat and beat with an electric mixer until it reaches the ribbon stage (light, fluffy, and thick).
Add the vanilla extract for flavor.
Sift the flour twice.
Gently fold the flour into the egg mixture using a spatula, making soft, folding motions to avoid deflating the batter.
Pour the batter into a round pan (24 cm in diameter and 4 cm in height) that has been greased with butter and dusted with flour.
Bake at 180°C (350°F) for 30 to 35 minutes.
The Genoise is ready when it begins to pull away from the edges of the pan and a toothpick inserted in the center comes out clean.
Remove from the oven and let it rest for 5 minutes. Invert onto a wire rack and unmold.
Ensure the eggs and sugar mixture reaches 40°C to achieve the right texture.
Sift the flour twice to prevent lumps and ensure a smooth batter.
Fold the flour gently to avoid deflating the batter.
Wrap the cake while slightly warm for freezing to retain moisture.
