Heat honey, syrup and fat in a pot while stirring slowly until the fat has melted. Pour into a mixing bowl and chill. Stir the eggs, spices and lemon zest with the whisk of the hand mixer into the almost cooled mixture.
Mix flour, baking powder and cocoa and stir in by the spoonful. Add trail mix to the dough and fold in. Spread the dough on a greased baking tray (32 x 27 cm) and bake in a preheated oven (electric cooker: 175 °C/ gas: level 2) for approx. 20 minutes.
Let the cake cool down. Mix icing sugar with lemon juice and spread the cake with it. Mark pieces measuring approx. 9 x 4 cm on the icing. Decorate with hazelnuts, chocolate flakes and the halved cherries.
Allow to dry and cut open just before serving. Results in about 24 pieces.
