Mix the flour, cocoa powder, and salt. Add the eggs to the center of the flour mixture and mix well.
Add the water and then knead the mixture together until a smooth dough is formed.
Wrap the dough in cling wrap and put it in the refrigerator for 30 minutes.
Separate the refrigerated dough into four parts, and roll out into a thin sheet with a rolling pin. Then cut the dough into long pasta noodles. This can also be done with a pasta machine.
Add a bit of salt to some boiling water and cook the pasta for 2-3 minutes.
For the sauce, cook the butter, sugar, and water together in a pan. Allow the sauce to thicken a bit so that the sugar can caramelize.
Add the chocolate noodles to the sauce. After plating your pasta, try topping it with walnuts and chocolate shavings. A touch of vanilla sauce is also a great option!
