Add turkey, chili powder, cumin, chipotle peppers, adobo sauce, and cocoa powder. Cook for 5-7 minutes until turkey is cooked through, breaking it up into small pieces with your spatula. Add sweet potatoes and broth and bring to a boil.
Add about half of the chili to a blender and blend until smooth. Add back into the pot and stir to combine. Be very careful when blending hot liquids because your blender can explode! To be safe, you could cool the soup a little bit and then blend. Or, you could use an immersion blender. Top with cilantro and any other toppings you like!
