A light and airy sponge cake made with whipped eggs and minimal ingredients. Perfect for layering, rolling, or enjoying simply with fruit and cream.
4 large eggs (room temperature)
⅔ cup granulated sugar
1 cup cake flour (or ¾ cup all-purpose + 2 tbsp cornstarch)
¼ tsp salt
1 tsp vanilla extract
1 tsp lemon zest (optional)
Preheat oven to 350°F. Line the bottom of a 9″ round pan with parchment (don’t grease sides).
Sift flour, salt, and cornstarch (if using). Set aside.
Beat eggs and sugar on high for 7–8 minutes until thick and pale.
Gently fold in vanilla and lemon zest.
Sift dry ingredients over the egg mixture in batches, folding gently each time.
Pour batter into pan, smooth top, and tap to release bubbles.
Bake 25–30 minutes, until golden and springy.
Cool 10 minutes, remove from pan, and let cool completely.
Use immediately for layering, rolling, or slicing. Store wrapped at room temp or freeze.
