Prepare the Oven and Baking Sheet: Preheat your oven to 400°F. Line a large rimmed baking sheet with parchment paper or a silicone baking mat to prevent the cauliflower wings from sticking and to make cleanup easier.
Make the Batter: In a medium mixing bowl, whisk together the all-purpose flour, paprika, garlic powder, plant-based milk, and water until the batter is smooth and lump-free. Season generously with sea salt and black pepper for extra flavor.
Coat the Cauliflower Florets: Dip each floret into the batter, ensuring it is evenly coated on all sides. Allow any excess batter to drip off before placing the florets onto the prepared baking sheet. Arrange them in a single layer so they bake evenly and crisp up nicely.
Bake Until Lightly Golden: Place the baking sheet into the preheated oven and bake for about 20 minutes, or until the coating becomes lightly golden and slightly crispy around the edges.
Toss with Buffalo Sauce: Remove the cauliflower from the oven and transfer the florets to a large bowl. Pour the buffalo sauce over the cauliflower and gently toss until every piece is evenly coated.
Bake Again Until Crispy: Return the coated cauliflower to the baking sheet and bake for another 15 to 20 minutes. The sauce will caramelize slightly while the edges become crispy and delicious.
Serve and Enjoy: Serve the buffalo cauliflower wings immediately, while they are warm and crispy. Pair them with vegan ranch, vegan blue cheese, vegan sour cream, or your favorite dairy-free dipping sauce.
