In a blender, combine dragon fruit (skin removed), condensed milk, half and half and monk fruit or your preferred sweetener. Blend until smooth. Pour the blended mixture into a Ninja Creami pint container, making sure it does not exceed the max fill line.
Place the pint container in the freezer and freeze for at least 18-24 hours.
After freezing, remove the pint container from the freezer and place it into the Ninja Creami machine. Attach the pint holder lid and lock it into place. Select the "Lite Ice Cream" setting and let the Ninja Creami process the mixture.
If the mixture is crumbly after the first spin, select the "Respin" function and process again until you achieve a creamy consistency. I only needed to do one additional spin.
Scoop the dragon fruit ice cream into bowls and top with your favorite toppings, such toasted shredded coconut flakes.
Notes
