Mix flour, nuts, baking powder, sugar, salt and lemon zest in a bowl. Add egg and butter in pieces. Knead first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Grease a fruit base form (approx. 26 cm Ø) well. Roll out short pastry to the size of the mould and press it into the mould.
Prick the base several times with a fork. Chill for about 1 hour. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 20-30 minutes. Remove the finished cake base from the pan immediately and let it cool down
