In a nonstick sauce pan over medium low heat, combine the chocolate morsels with the milk, butter, and granulated sugar stirring until all the chocolate is melted and ganache is smooth and shiny. Allow to cool for 15 minutes in the sauce pan but off the heat.
Use a rubber spatula to scrape all of the ganache onto the pie, filling in all of the nooks between the nuts. If it looks as though you have too much ganache, set overage aside to serve with chilled pie later.
Refrigerate to cool completely. I go minimum 2 hours.
To serve, cut the pie into 8 equal slices and plate. Garnish with whipped cream, cookie pieces, peanut butter candies, small pieces of peanut brittle, additional whole or chopped nuts, caramel sauce, or chocolate sauce, etc. This step is limited only by your imagination, so get creative!
