Bake the sweet potatoes: Preheat oven to 200°C (400°F). Prick the sweet potatoes a few times with a fork, place on a baking tray, and bake for 40–50 minutes until soft and tender.
Make the buffalo chickpeas: Heat olive oil in a frying pan over medium heat. Add chickpeas, garlic powder, smoked paprika, salt, and pepper. Cook for 5–7 minutes until golden and a little crisp. Stir in the buffalo sauce and maple syrup, and cook for another 2–3 minutes until coated and sticky.
Assemble your potatoes: Slice each baked sweet potato open lengthways. Fluff the inside with a fork, then stuff with buffalo chickpeas. Add diced avocado, a dollop of sour cream, and sprinkle with parsley or spring onion. For extra indulgence, crumble a little feta or blue cheese over the top.
