This recipe, arguably the recipe most closely identified with the Bake-Off® Contest, mysteriously develops a "tunnel of fudge" filling as it bakes. Don't scrimp on the nuts, or it won't work!
* Nuts are essential for the success of this recipe.
** Since this cake has a soft filling, an ordinary doneness test cannot be used. Accurate oven temperature and baking times are essential.
