Food Network and In A Southern Kitchen both have simple recipes for old-fashioned fudge pie. Food Network's recipe uses real chocolate to flavor the pie, while In A Southern Kitchen's recipe uses cocoa powder.
To make Food Network's recipe for old-fashioned fudge pie, first preheat the oven to 375 degrees Fahrenheit. Melt 2 ounces of semi-sweet chocolate and 1/2 cup butter in a heavy saucepan. Once the butter and chocolate are completely melted, remove the mixture from the heat, and add 1 cup sugar. Stir well, then add 2 eggs. Pour the filling into an unbaked store-bought pie crust, and bake for 25 minutes or until just set.
