Preheat your oven to 450°F (230°C).
Prepare the batter by whisking together flour, water, garlic powder, smoked paprika, and salt.
Coat the cauliflower florets in the batter, allowing any excess to drip off.
Arrange the battered florets on a parchment-lined baking sheet, ensuring space between each piece.
Bake in the preheated oven for 20-25 minutes, or until golden brown.
In a separate bowl, mix the Buffalo sauce and melted butter.
Toss the baked cauliflower wings in the Buffalo sauce mixture until well coated.
Return the wings to the oven for an additional 10 minutes.
Garnish with fresh parsley before serving, if desired.
