Fill a large pot with lightly salted water and bring to a rolling boil over high heat. Once the water is boiling stir in the egg noodles and return to a boil. Cook the pasta uncovered, stirring occasionally until the pasta has cooked through but is still firm to the bite, about 5 minutes. Drain well in a colander set in the sink.
Place noodles in a large bowl. Mix margarine into the noodles until melted. Stir in the eggs, sugar, apple sauce and vanilla essence. Pour noodle mixture into a 20x30cm baking dish then sprinkle with cinnamon. Cover baking pan with aluminium foil.
Bake in the preheated oven for 30 minutes. Uncover the kugel and bake until golden brown, 20 to 30 minutes.
