In a small bowl, sprinkle the gelatin over the cold water and let stand while preparing the rest of the mixture.
In a small saucepan, bring 1 cup cream to a simmer over medium heat. Stir 1/2 cup of the warm cream into the gelatin/water mixture and stir until the gelatin is completely dissolved.
Add the chocolate chips to the cream that is left in the saucepan and stir until the chocolate is melted.
Add the gelatin mixture to the chocolate mixture and then add the remaining 1/2 cup whipping cream. Stir until well combined.
Pour into the prepared loaf pan and then cover with plastic wrap. Refrigerate for about 45-60 minutes or until firm
