For the Cauliflower: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it with cooking spray.
- Cut the cauliflower into bite-sized florets, trying to keep them roughly the same size for even cooking.
- Make the Batter: In a large bowl, whisk together the flour, garlic powder, onion powder, smoked paprika (if using), salt, and pepper. Add the plant-based milk and olive oil, whisking until smooth. The batter should be thick enough to coat the cauliflower florets without dripping off.
- Coat the Cauliflower: Dip each cauliflower floret into the batter, ensuring it’s fully coated. Arrange the battered cauliflower on the prepared baking sheet, making sure they are not touching to allow for even crisping.
- Bake the Cauliflower: Bake for 25-30 minutes, flipping the florets halfway through, until the cauliflower is crispy and golden brown on the edges.
- For the Buffalo Sauce: While the cauliflower is baking, prepare the buffalo sauce by whisking together the hot sauce, melted vegan butter, maple syrup (if using), and apple cider vinegar. Adjust the heat level by adding more hot sauce or sweetness by adding more maple syrup.
- Assemble the Wings: Once the cauliflower is done baking, remove it from the oven and place it in a large bowl. Pour the buffalo sauce over the cauliflower and gently toss until all the florets are evenly coated.
- Serve: Serve the spicy vegan cauliflower buffalo wings immediately with your favorite dipping sauce, like vegan ranch or blue cheese, and a side of celery or carrot sticks.
