Preheat oven to 210°C or 425ºF. On a baking sheet, prick the skin of the sweet potatoes all over with a fork. Bake for about 40 to 50 minutes until they are nice and tender.
Let the baked sweet potatoes cool and peel the skin off.
Place all the remaining ingredients into a blender and let it blend for about 5 minutes until everything is nice and smooth.
Serve it as a dip in a bowl with a drizzle of chili oil, a sprinkle of pumpkin and sesame seeds, alongside some crackers or fresh vegetables.
