For the base, mix 200 g flour, sugar and baking powder in a bowl. Add 100 g margarine in pieces and soy drink. Knead first with the dough hooks of the mixer, then briefly with your hands to a smooth dough. Cover and chill for about 30 minutes. Grease a springform pan (26 cm Ø) with margarine and dust with flour
Crumble the tofu for the filling. Puree with 1⁄4 l soy drink with a hand blender until creamy. Stir in 200 g sugar. Mix starch and pudding powder with the rest of the soy drink until smooth. Stir in the tofu puree and whipping cream
Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: see manufacturer). Spread the dough with floured fingers in the mould and press it down, forming a rim approx. 5 cm high. Place the frozen berries on top and press down lightly. Stir the filling briefly and then pour on
Place in the hot oven on the lowest shelf. To cover, slide a baking tray onto the middle rail. Bake for about 70 minutes (the cake will still wobble a little in the middle). Remove from the oven. Let it cool down, carefully remove from the tin
Waiting time approx. 20 minutes
