Step 1

Line an 8 or 9 inch square pan with a large piece of foil or plastic wrap, leaving the ends out to cover the finished fudge.

Stir in nuts if you want and pour fudge mixture into the pan.

Step 8

Spread into the pan.

Step 9

Let sit a bit and then cover the top with foil or the plastic wrap.
