Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Wash, clean and drain the strawberries and, depending on size, cut them in half or quarters.
Mix 200 g butter, sugar, vanilla sugar and 1 pinch of salt with the whisk of the mixer for 4-5 minutes until creamy. Alternately stir in eggs and 1 tablespoon of cornflour. Mix 200 g flour, rest of starch and baking powder and stir in briefly.
Smooth the dough in a greased and floured baking tray (approx. 30 cm Ø). Spread strawberries on top. Sprinkle with pine nuts and brown sugar. Bake in a hot oven for approx. 45 minutes (stick test). If necessary, cover the last 10 minutes with aluminium foil.
Let it cool down on a cake rack. Serve dusted with icing sugar. Whipped cream tastes good with it.
