Saftiger Zitronenkuchen

Steps

1. Preheat the oven to 180°C (356°F) top/bottom heat.
2. Beat the butter, sugar, and vanilla extract together until creamy using a hand mixer or stand mixer.
3. Add the eggs one at a time, beating for about 1 minute after each addition.
4. Wash the lemons in hot water and dry them. Zest both lemons and juice one of them. Stir the zest and juice into the butter-egg mixture.
5. Mix the flour, ground almonds, salt, and baking powder together. Fold gently into the wet mixture until just combined.
6. Grease a loaf pan with butter and dust with flour, or line with parchment paper. Pour in the batter and smooth the top.
7. Bake in the center of the preheated oven for 45-50 minutes, covering with foil if the top browns too quickly.
8. Toward the end of baking, test with a wooden skewer; the cake is done when it comes out clean.
9. Let the cake cool in the pan, then transfer to a wire rack to cool completely.
10. For the icing, mix the powdered sugar with the remaining lemon juice until smooth, then drizzle over the cooled cake.
