Place the puff pastry slices next to each other and allow to thaw. In the meantime grease 4 large Tartelett moulds (150 ml content). Sprinkle with breadcrumbs. Halve the pastry slices, roll out a little thinner. Put them into the moulds and press them down. Put the Tartelettes in a cool place. For the filling, mix sugar, egg, quark, yoghurt, starch, cocoa and espresso.
Put 25 g mocha beans and quark mixture into the cooled moulds. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: stage 2) for 40-45 minutes. Let them cool down a bit, remove the edges with a sharp knife and turn them out of the tins, let them cool down completely. Dust with cocoa and icing sugar. Serve with 1 ball of strawberry ice cream. Decorate with remaining mocha beans
