Finely grate the lemon peel and squeeze the juice into a small bowl.

Preheat your oven to 200°C using the standard setting. Line a baking tray or a pastry frame with parchment paper.

Whip the butter and sugar until it’s smooth and creamy. Add the eggs one at a time, then pour in the flour, baking powder, salt, lemon juice, and zest. Stir everything together until your batter looks nice and even.

Spread the batter evenly on the prepared tray. Bake for about 18–20 minutes. To check if it’s done, stick a toothpick in the middle—if it comes out clean, it’s ready.

Place the baked cake on a cooling rack and let it cool fully. After that, carefully remove the parchment paper.
06 -
Blend the lemon juice with the powdered sugar. Adjust the mix until it’s thick enough to spread while still smooth.

Spread the icing across the cooled cake. Add lemon slices or bits on top if you like. Let it set before you slice and serve.
