What should the consistency of pudding be?
It sounds to me like you are making your pudding almost as thick as it should be.

It should be able to stand up a little. In other words, if you spoon some into a desert cup or small bowl, it should make a pile. It shouldn't be solid like ice cream, it should be smooth, but still stay in a pile shape.

Do you have custard where you live? It should be similar to that in thickness. Though custard is very different from
Chocolate pudding.
