Cook the pasta in plenty of salted water for about 10 minutes. Mix eggs, starch, vanillin sugar, sugar, 1/2 litre milk and lemon peel. Drain the noodles and let them drain. Grease a flat casserole dish.
Roll the pasta into nests and place in the mould. Pour over vanilla milk and bake in the preheated oven (electric: 200 °C/ gas: level 3) for approx. 30 minutes. Roughly chop the trail mix and after half the baking time, place 1 tablespoon on each noodle nest.
Warm up the remaining milk and cream. Roughly chop the chocolate and melt in the milk. Leave to cool and serve with the pasta casserole.
