For the lemon sheet cake, squeeze the lemons and grate the zest. Put both in a food processor with sugar, butter, flour, eggs, baking powder and honey and mix to a dough.
Preheat the oven to 160 °C, line a baking tray with baking paper and spread the dough evenly on it.
Bake for 25 minutes (test with a stick) and do not let the cake brown.
Mix the powdered sugar with the juice of one lemon and glaze the cooled cake with it.
Preparation Tip:
Lemon sheet cake also tastes delicious when prepared with nuts.
