3/4 cup evaporated milk
2 cups sugar
1/4 cup butter
1/4 t salt
1 cup marshmallow creme AND 1 cup mini marshmallows
1 1/2 cups chocolate chips
1/2 t vanilla
1/2 cup chopped nuts, if desired
Over medium high heat, stirring constantly, cook milk, sugar, shortening and salt together until it reaches the soft ball stage (234 degrees) -- about 5 or 6 minutes.
Remove from heat and IMMEDIATELY stir in chocolate chips. Add marshmallow creme and marshmallows, vanilla, and nuts. Pour into greased flat pan, 8x8x2" (or larger if you want the fudge not so thick).
SUBSTITUTION: Instead of the marshmallow creme, you can use 6 cups of mini marshmallows (which is about a 10-1/2 oz bag of mini marshmallows). I sometimes use a little more if it feels like the fudge isn't thick enough.
