Heat olive oil in a large pot over medium-high heat and add onion and garlic. Cook for about 3-5 minutes, until onions become translucent.
Carefully stir in the pumpkin, vegetable stock, coconut milk, maple syrup, ginger, cinnamon, nutmeg, salt, and cayenne (if using).
Bring to a boil, then turn the heat to low and simmer for about 20 minutes, until the soup has reduced and thickened slightly.
Puree with an immersion blender or in a stand blender until very smooth. Garnish with pepitas, cashew cream, and hot sauce.
Enjoy!
