  • 3 large eggs
  • 2 large egg yolks
  • 1 1/2-3/4 cups granulated sugar check the sweetness of your sweet potatoes and adjust sugar accordingly
  • 1/4 cup brown sugar
  • 1 cup sweet potato roasted or microwaved then mashed
  • 2 tablespoons pure vanilla extract
  • 1/2 teaspoon cinnamon
  • 2 cups heavy whipping cream
  • 2 cups half and half
  • 1 1/2 cups mini marshmallows toasted under broiler in oven (place on parchment paper and separate, toast only a few minutes before ice cream is done churning)


  • Whisk eggs and egg yolks in a medium sized bowl. Next add both sugars, mashed sweet potato, vanilla extract and cinnamon to the bowl and whisk together. Set aside.
  • Add heavy cream and half and half to a medium pot and heat to boiling level. Remove from heat.
  • Slowly add three tablespoons of the hot milk mixture to the egg mixture to temper it and whisk together to combine. Then slowly add in the rest of the milk mixture and continue whisk the entire time to make sure it doesn't scramble.
  • Pour the entire mixture into a blender and blend until sweet potato is smooth.
  • Place the mixture in the refrigerator for 2-3 hours to chill completely.
  • Add mixture to your ice cream maker and churn according to the manufacturer's instructions.
  • Once ice cream is done churning, alternate adding ice cream and toasted marshmallows to freezer safe container.
  • Freeze for at least 3-4 hours then serve. Store in freezer when not serving. Best eaten within 3-4 days of making.


I prefer to roast the sweet potatoes in the oven at a high temperature of about 400-425 degrees (pierce them, oil them then cover in foil before roasting) for about an hour or so or until totally tender.  It makes them so soft and just the perfect texture.  To speed this up, you can always do this in the microwave but you have to be careful since the texture can become gummy in my opinion.
