Separate eggs. Beat the egg whites with the whisks of the hand mixer until stiff. Gradually add sugar, 1 packet of vanilla sugar and salt. Add egg yolk and stir in. Mix flour, starch, baking powder and cappuccino powder and sieve onto the egg sugar mixture.
Carefully fold in. Line the bottom of a springform pan (26 cm Ø) with baking paper. Fill in the dough and smooth it down. Bake in a preheated oven (electric: 200 °C/ gas: level 3) for 25-30 minutes.
Let the base cool down on a cake rack. Remove the cake from the tin and cut through once crosswise. Drain the peaches on a sieve. Warm the jelly in a pot while stirring. Let it cool down a bit and spread it on the bottom cake base.
Cut peaches into pieces except for one half for decoration. Whip 1 1/2 cup of cream, cream firmer and remaining vanilla sugar until stiff. Fold in the peach pieces and also spread them on the lower cake base.
Place second bottom on top. Whip the rest of the cream until stiff and, except for about 1/4 for decoration, spread the cake all around. Pour the remaining cream into a piping bag with a star-shaped spout and decorate the cake as desired.
Roast the nuts in a dry pan over medium heat for 3-4 minutes. Remove from the pan and allow to cool. Decorate the cake edge with the nuts. Cut the remaining peach half into narrow slices and halve.
Place one half of each column on the cream tuffs and sprinkle with nuts. Results in about 12 pieces.
