Easy, Foolproof 3-Ingredient Génoise Sponge Cake: Light, Soft, and Airy
The 3-ingredient homemade génoise (sponge cake) is one of the most valuable staples in French pastry. With its light texture, soft center, and delicately airy crumb, it is perfect for any occasion—whether you’re making a strawberry cake (*fraisier*), a birthday cake, a Black Forest gateau, a Yule log, or an elaborate layered dessert. It’s the kind of recipe you’ll want to keep on hand for easily whipping up delicious, homemade treats.
The secret? No butter, oil, or baking powder required. Eggs, sugar, and flour are all you need to create a beautifully risen, supple sponge—provided you follow a few essential steps. Whisking the eggs properly, folding in the flour with care, and mastering the baking process make all the difference.
This recipe uses a *bain-marie* (water bath) technique to help the eggs gain volume and form a stable foam. The result is a golden sponge that is easy to slice into layers—ideal for pairing with pastry cream, whipped cream, chocolate ganache, or fresh fruit.
Whether you are a beginner or an experienced home baker, here is a detailed method to ensure your génoise turns out perfectly every time, while avoiding common pitfalls.
