In a bowl, whip the heavy cream until stiff peaks form.

Combine pumpkin puree, condensed milk, and spices in a separate bowl. Stir until combined. 

Use a spatula to fold the sweetened condensed milk mixture into the heavy cream. Careful not to break down the cream. 

Once thoroughly combined, pour the mixture into a dish lined with parchment paper. I used a loaf pan, but you can use whatever you'd like!

Place in the freezer until frozen, and enjoy!
