This recipe was given to me by a coworker several yrs ago and has never failed to come out wonderfully smooth and delicous.
1 stick butter
4 1/2 cup sugar
1 can pet evaporated milk
Put into a HEAVY PAN, to prevent scorching.Bring to a boil and cook 11 min, stirring often.
Remove from heat and add;
1 small jar marshallow cream
1- 12oz bag chocolate chips
1 teaspoon vanilla
Beat until everything is well blended(mixer is good)Pour into buttered 9x12 dish, Cool and cut ito sqs. I add about 1/2 c
peanut butter for taste, can also add nuts. I have used peanutbutter chips instead of choc. Enjoy!
