Cream butter, cream cheese and sugar with the whisk of the hand mixer. Add the eggs bit by bit and mix well each time. Wash the lemon hot and grate it dry. Grate the peel thinly, squeeze out the juice.
Mix flour, salt, baking powder and baking soda. Stir lemon zest, 2-4 tbsp. lemon juice and flour mixture into the egg mixture. Pour into a greased and flour-spread pancake tin (approx. 2 1/2 litres capacity).
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 1 hour. Take out the finished cake and let it rest in the pan for a short time. Turn out the cake and let it cool down.
Dust with icing sugar if necessary. Strawberry cream tastes good with it.
