Beat the eggs and sugar until light and fluffy. This will take a few minutes.
Add the lemon zest, flour, baking powder, and salt. Gently fold everything into the batter.
Using two tablespoons, scoop mounds of batter onto a baking sheet. Use a generous spoonful for each cookie and leave space between them. They will spread and rise.
Bake for about 10 minutes at 350°F /180°C (conventional oven).
The cookies should still look fairly pale, but the edges should just start turning golden. If you bake them too long, they’ll become dry and crumbly.
