Grease a springform pan (26 cm Ø) and sprinkle with breadcrumbs. Carve peaches crosswise, blanch with boiling water and rinse with cold water. Peel skin, cut peaches in half and remove the stone. Cut 8 peach halves into 3 slices each. Dice remaining 2 halves, puree with 2 teaspoons sugar and lemon juice. Put them in a cold place
Cream fat, 100 g sugar, vanillin sugar and salt. Stir in the eggs one by one. Mix flour and baking powder and stir in briefly. Brush into the mould. Spread the peach slices on top and press down gently. Dust with icing sugar. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for about 30 minutes. Let them cool down
Put the prosecco in a mixing bowl. Add both bags of cream powder and mix briefly with the hand mixer. Then beat at highest speed for approx. 3 minutes until frothy. Chill for about 5 minutes.
Whip the cream until stiff, allowing the cream firmer to trickle in. Fold into the cream and spread on the peach base in waves. Chill for about 3 hours. Dribble the peach puree into the hollows with a spoon. Decorate the cake if necessary
