Preheat the oven to 350°F (175°C)
Grease and line a cake pan with parchment paper
Separate the eggs if using a separated-egg method
Beat the eggs and sugar until thick, pale, and fluffy
Sift the flour and any dry ingredients together
Gently fold the dry ingredients into the egg mixture
Add melted butter or oil if the recipe calls for it
Pour the batter into the prepared pan
Tap the pan lightly to remove large air bubbles
Bake until the cake is golden and springs back when touched
Check doneness with a toothpick inserted into the center
Remove the cake from the oven and let it cool in the pan briefly
Turn the cake out onto a wire rack to cool completely
Slice and serve once fully cooled
