Pour the Heavy Whipping Cream, Egg yolks, Vanilla, and Pyure into a medium saucepan.
Heat on medium heat until it comes to a simmer. Turn off and pour into an 8x8 with parchment paper in it.
Chill in the freezer for 20 minutes then remove from the freezer and add the Chocolate chips, walnuts, and chopped banana.
Return to the freezer for the rest of the 4 hours. Then remove and cut into 9 bars.
Melt the Moser Roth Chocolate bars and coconut oil.
Dip each of the bars into the melted chocolate then return to the freezer to harden. They're best after about 10 minutes in the freezer but are still amazing if you don't decide to leave them in longer!
