Preheat your oven to 350°F (175°C) and line an 8-inch round cake pan with parchment paper. Ensure all ingredients are at room temperature.
In a large bowl, combine eggs and sugar. Using an electric mixer, beat on high speed for 7-8 minutes until the mixture triples in volume and becomes pale yellow. The mixture should form "ribbons" when the beater is lifted.
Sift the flour directly over the egg mixture in three batches, gently folding after each addition with a spatula. Use a figure-eight motion, cutting through the center and around the sides to preserve the air bubbles.
Pour the batter into your prepared pan, smoothing the top gently. Bake for 25-30 minutes until golden and a toothpick inserted comes out clean. The cake should spring back slightly when touched.
Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
