Mix the remaining cookie pieces into the mixture and pour into the prepared pan. *If desired, decorate fudge in orderly rows, so each piece of fudge has a sliver of cookie on top as garnish. This decorating has to happen when the fudge is still hot. An example of this decorating technique can be seen at the top of this post!
Put the fudge into the refrigerator (or your local snowdrift) for 2-3 hours. I have this routine down pat, but when making this delicacy, you hafta plan for the time to set, as cutting the fudge when it is still hot or even room temperature can be a very messy endeavor. I usually make five rows of six (30 squares) but this pan is arranged in another way, to make room for the design look I was interested in creating on each square.
