In a large bowl, mix flour, cocoa powder and salt together with a wire whisk. Pour the flour mixture into a large bowl. Make a deep well in the center of the mound and break the eggs into it. Mix the eggs with a fork, adding 1 Tbsp oil and 1 tsp vanilla. Stir with your fork until you form a soft dough. When you have formed a soft, dough ball, transfer it to a clean, floured working surface and knead for 5-10 minutes until the dough is soft, elastic and uniform in color. Cover the dough with plastic wrap and let it rest for an hour before rolling.
Roll the dough through your pasta machine and use your spaghetti, linguini or fettuccine cutting attachment. Cook your pasta in unsalted, boiling water for 2 – 3 minutes. Drain thoroughly but do not rinse.
Mound your warm pasta onto dessert plates and serve immediately with sauce, or chill to serve cold.
