6 large eggs
1 cup granulated white sugar (200g)
1 cup all-purpose flour, sifted (120g)
1 tbsp cornstarch (7g)
Step number one. Preheat oven to 350°F / 175°C. Line the bottom and the sides of three 8? (20cm) baking pans with parchment paper. Set aside.
Step 02, Make the genoise cake: In a large mixing bowl, using a handheld or stand mixer fitted with a whisk attachment, whisk eggs on medium speed just until combined. Add sugar and whisk on medium-high speed for about 10-12 minutes until white pale, foamy and tripled in size. (It takes 3-5 minutes longer with a handheld mixer compared to a stand mixer). To know if you have the right consistency, let a bit of batter drip off the whisk attachment on top of the mixed batter. The dripped batter should be visible for 10 seconds before it sinks into the batter. If it sinks earlier, you need to whisk longer.
And then, With a wooden spoon, fold in flour, cornstarch baking powder carefully. Don’t overwork the batter and don’t work too fast otherwise, it will lose too much air. Divide in prepared baking pans and bake for 20-22 minutes until a toothpick centered in the middle comes out clean. Let cool in the pans for 5 minutes. Then remove from pans and remove the paper immediately. Transfer to a wire rack and let cool completely.
