Pre-heat oven to 250 degrees to roast the white chocolate.
Add white chocolate to a small baking dish and bake for 60 minutes. Every 10 minutes, stir as it melts to keep it smooth. It should turn a nice caramel color.
In a stand mixer or with a hand mixer, whip the cream and condensed milk until soft peaks form.
Remove white chocolate from oven and let cool slightly.
Mix into the cream half of the white chocolate mixture and then fold in the chocolate chips.
Transfer to a 9X5 loaf pan and then add the remaining white chocolate and with a skewer, swirl it through the cream.
Cover and put in freezer to set overnight or at least 6 hours.
