Wash and clean the strawberries. Depending on the size, halve or quarter them. Crumble meringue coarsely.
For the dough, mix flour, starch and baking powder. Mix butter, 225 g sugar, vanilla sugar and 1 pinch of salt with the whisk of the mixer for about 5 minutes until creamy. Stir in eggs individually and alternately with 1 tbsp. flour mixture. Stir in the rest of the flour mixture briefly. Fold meringue, except for a little bit for sprinkling, and strawberries loosely into the dough.
Spread the dough into a greased and flour-strewn fat pan (approx. 32 x 39 cm). Sprinkle with 75 g sugar. Bake in a preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for approx. 45 minutes. Sprinkle cake with remaining meringue and let it cool down. Whipped cream goes well with it.
