Simple Vanilla Sponge Cake with Self-Rising Flour

1.Preheat the oven to 350°F (175°C). Grease an 8-inch (20cm) round cake pan with butter.

2.In a large mixing bowl, beat the eggs and granulated sugar together using an electric mixer on high speed until the mixture is pale, thick, and tripled in volume, about 5-7 minutes.

3.Sift the self-rising flour to ensure no lumps and even distribution.

4.Gently fold the sifted self-rising flour into the egg mixture in three additions using a spatula, folding lightly to keep the batter airy.

5.In a small bowl, combine the warmed water, melted butter, and vanilla extract if using. Slowly drizzle this mixture into the batter, folding gently until fully incorporated and smooth.

6.Pour the batter evenly into the prepared cake pan, smoothing the top with a spatula.

7.Bake in the preheated oven for 25-30 minutes, or until the cake is golden brown and a toothpick inserted into the center comes out clean.

8.Let the cake cool in the pan for 10 minutes, then run a knife around the edges and invert onto a wire rack to cool completely.
