Two Ingredient Pumpkin Ice Cream

large or 6 small very ripe bananas (lots of black spots), frozen

fresh or canned pumpkin puree (this canned pumpkin doesn't have undisclosed ingredients like many supermarket canned pumpkin!)

Optional: raw honey, pure maple syrup, non-irradiated cinnamon or chocolate chips (I love these chocolate chips, they are dairy and soy free!)
