Step 5

(or you can test if it's done by putting a spoonful of the boiling mixture into a cup of ice water. If you form it into a soft ball, it's ready).

Step 6

Remove from the heat and stir in the marshmallows or marshmallow creme until the mixture is smooth.

Step 7

Pour the mixture over the chocolate chips and stir until all the chocolate is melted and the mixture is smooth. Add the nuts if using.
