In a high speed blender like a vitamix, mix all of the ingredients, reserving the gelatin, on high and blend until combined.
Pour the mixture into a sauce pan and heat on medium heat. Add the gelatin little by little, stirring in to make sure there are no clumps and heating on medium for about 5 minutes.
Remove from heat and allow to cool.
Add the mixture to pumpkin molds and refrigerate for at least an hour.
