Ingredients:
- 4 large eggs, at room temperature
- 1 cup (200g) granulated sugar
- 1 tsp vanilla extract
- 1 cup (120g) all-purpose flour, sifted
- 1/4 tsp salt
- 1/4 tsp cream of tartar (optional, helps stabilize egg whites)
- 1/4 cup (60g) unsalted butter, melted (optional for extra moisture)
- 1/4 cup (60ml) milk (optional, for a moister cake)
Instructions:
- Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper for easy removal. - Prepare the Eggs:
Separate the egg whites from the yolks, placing the egg whites in a large clean mixing bowl. Beat the egg yolks with sugar in a separate bowl until it becomes pale and slightly thickened. - Whip the Egg Whites:
Add the cream of tartar (if using) to the egg whites and beat with an electric mixer or stand mixer until stiff peaks form. This will take about 5-7 minutes. - Mix the Yolks and Vanilla:
Add the vanilla extract to the egg yolk-sugar mixture and mix well. - Combine the Flour and Egg Yolks:
Sift the flour and salt together. Gently fold the dry ingredients into the egg yolk mixture until just combined. Be careful not to deflate the batter. - Fold in the Egg Whites:
Gradually fold the whipped egg whites into the batter. Be very gentle to preserve the air in the mixture for a light and fluffy cake. - Add Butter and Milk (Optional):
If you prefer a slightly richer cake, you can fold in the melted butter and milk at this point. This step is optional, but it will add some extra moisture and flavor. - Pour the Batter into the Pan:
Pour the batter into your prepared cake pan, spreading it out evenly. - Bake the Cake:
Bake for 25-30 minutes or until the cake is golden brown, and a toothpick inserted into the center comes out clean. The cake should spring back when lightly pressed. - Cool the Cake:
Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. - Serve:
Once cooled, you can serve the vanilla sponge cake as is, or top with whipped cream, fruit, or frosting if desired.
