Mix flour, starch and baking powder and stir in portions. Pour the dough onto a greased fat pan of the oven (32 x 39 cm) and smooth it down. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 20 minutes.
Remove, place on a rack and let cool off. Wash and clean the strawberries and drain well. Boil up 850 ml milk and 250 g cream in a pot. Meanwhile mix 150 ml milk, pudding powder and 75 g sugar.
