Cover 2 baking trays with baking paper and draw a circle (26 cm Ø) on each. Beat the egg white and salt until very stiff, adding sugar and cornstarch. Pour meringue mixture into a piping bag with a large perforated spout.
Spray the recorded cresia spirally. Let both bottoms dry in the preheated oven (electric cooker: 80 °C / gas: level 1) with slightly opened oven door for approx. 1 1/2 hours. Soak gelatine in cold water.
Whip the cream until stiff. Squeeze the gelatine and dissolve in a little cream over a mild heat. Fold into the rest of the cream. Pour approx. 1/3 of the cream into a small piping bag and set aside for decoration.
Remove the waffle base from 25 Mini-Dickmann "s and put them aside. Add the Mini Dickmann's to the cream, stir in a little and spread the mixture on a meringue base. Press the edges of the waffles against the cream, place the second meringue base on the cake and press down gently.
Spray the remaining cream onto the cake as spots. Decorate with remaining Dickmann "s (without the waffle base). Put the cake in a cool place for about 2 hours. Dust with cocoa as desired. Makes 12 pieces.
