Mix 4 tablespoons of milk and pudding powder. Bring the rest of the milk to the boil and add the pudding powder while stirring. Bring to the boil again briefly, pour into a bowl, cover with foil and allow to cool.
Roast the flaked almonds in a pan without fat while turning them golden brown, let them cool down on a plate. Place a 22 cm Ø cake rim or a 24 cm Ø springform pan rim on a cake plate.
Place a layer of ladyfingers on the floor and sprinkle with 3-4 tablespoons of rum. Stir the cooled down pudding once vigorously. Stir butter and sieved icing sugar until creamy white. Stir in the pudding by the spoonful.
Finally add ground almonds. Spread a thin layer of butter cream on the soaked lady fingers. Place a new layer of ladyfingers on top, again sprinkle with rum and spread a thin layer of buttercream on top.
Repeat this again. Put the cake in a cool place for about 1 hour. Do not chill the rest of the buttercream. Remove the cake from the edge with a sharp knife. Spread butter cream all around and sprinkle with almond flakes.
Pour the rest of the cream into a piping bag with a large star-shaped spout. Spray 8 tuffs onto the cake and decorate with chocolate leaves. Keep cool until serving. Makes about 16 pieces.
