Chocolate Fudge

3 C sugar
¾ C butter
2/3 C evaporated milk
½ tsp salt
12 oz chocolate chips
7 oz marshmallow cream
(or equivalent of mini-marshmallows)
1 tsp vanilla
Optional: 1 C chopped nuts

Combine sugar, butter, evaporated milk and salt in a saucepan. Bring just to a rolling boil; remove from heat. Immediately stir in chocolate chips and marshmallows until completely combined and melted. Add vanilla and nuts, if desired, stirring until well blended. Pour immediately into container(s) lightly coated with non-stick spray. Cool. Cut into squares to serve.

For "rocky road fudge", add an additional cup of mini-marshmallows just before pouring into containers to cool; fold them gently into the fudge, just to combine -- but not to melt and mix them.
