Place the washed whole sweet potato in a glass baking dish with oil and seasoning. Poke it with a fork or a sharp knife a couple of times.
Bake the sweet potato in a pre-heated oven on 390 Fahrenheit (200 degrees Celcius) for 30 minutes. You know the sweet potatoes are ready if the skin looks shriveled and soft and you can pierce it easily with a fork.
Let the baked sweet potatoes cool a bit. If it is not too hot to touch, peel them and mash the insides with a fork. Now, it is ready to be used to make the chocolate pudding.
