This recipe is a keeper - I wouldn't change a thing. This is definately a favorite! Salty Peanuts add a nice contrast to the sweet fudgy flavor. Love it!
Yes, you could substitute walnuts for the peanuts. No, you should not need to add salt. The bars would be healthier without the added salt. Make them this way first. If your family is satisfied with them, great. If not, you could then try the recipe with one-fourth to one-half tsp. additional salt. Whenever you adjust a recipe always change only one ingredient at a time.
Instead of using salted peanuts, do you think I could substitute walnuts? Would I need to add more salt to compensate?
