Mix the espresso powder with 1/4 litre of boiling water, let it cool down. Grease a ring cake tin (2.5 litres capacity) well and sprinkle with breadcrumbs. Cut marzipan into cubes. Coarsely chop the mocha beans, except for 1 tablespoon. Cream fat, sugar, vanillin sugar and salt.
Beat the eggs separately. Mix flour, baking powder and cocoa. Alternate with the coffee and stir in portions. Fold in marzipan and chopped mocha beans. Pour the dough into the mould and smooth it down. Bake in the preheated oven on the lower rack (electric oven: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 1 1/2 hours. Cover after 1 hour if necessary. Remove from the oven and leave to cool in the mould for approx. 10 minutes. Turn out onto a cake rack and let it cool down.
