Best Fudge Ever!

This is my grandma’s recipe and it is SO good! It’s really easy to make. The trick is to continually stir while boiling.

3 cups white sugar
2/3 cup evaporated milk
3/4 cup margarine
1 pkg marshmallows (11oz) or 6 cups mini marshmallows
2 cups chocolate chips
1 cup chopped nuts (optional)
1 tsp vanilla

Combine sugar, margarine and milk in saucepan. Bring to full or rolling boil. Stir constantly.
Continue boiling for 5 mins over medium heat- stir, stir, stir!
Remove from heat, stir in chocolate chips until melted. Add marshmallows and mix. Add vanilla and nuts.
Beat until well blended.
Pour into greased 9×13 pan.
Leave on counter at room temperature to cool.
Cut into squares.
Enjoy!
