1- 7 oz jar Marshmallow Fluff
1- small can evaporated milk
3 cups white granulated sugar
1 tsp vanilla
1 1/2 sticks real butter
1- 12 oz package Hershey Dark Semi Sweet chocolate bit
Mix marshmallow, milk, sugar, vanilla, and butter, together over med heat, stirring constantly it it comes to a rolling boil.
Cook over med heat being careful to stir constantly so it does not scald or burn.. for exactly 5 minutes. After 5 minutes take off the heat and pour in the Dark semi sweet chocolate Bits. Stir til smooth..
I use a 7 x 9 pan, buttered.. Pour into the pan quickly after its been stirred to smooth.. place in refrigerator for 1 hr.. it will be cool enough to handle and take out of pan, yet soft enough to cut.
Cut into bite size pieces and place in a covered bowl, and place back into refrigerator to finish cooling.
