Coarsely chop the walnuts. Peel bananas and mash them in a bowl with a fork. Beat the sugar, 1 packet of vanilla sugar and margarine with the whisk of the hand mixer until creamy, stir into the bananas. Add soy milk. Mix flour and baking powder into the banana mixture. Mix everything to a smooth dough. Finally fold in chopped walnuts
Spread the dough evenly on 12 cup cake tins (each with a capacity of 75 ml) and bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 18-20 minutes
Remove Cup Cakes from the oven and let them cool on a cake rack. Let the raspberries thaw for about 30 minutes and puree. Whip the whipping cream and 1 packet of vanilla sugar with the whisk of the hand mixer. Just before the whipping cream is stiff, carefully mix in the pureed raspberries. Pour the whipping cream into a piping bag with star-shaped spout and decorate muffins with it. Sort the raspberries and decorate the muffins with them
Waiting time approx. 30 minutes
