Place onto the prepared baking sheet in a single layer. Bake for about 15 minutes until the batter just hardens.In a small bowl, mix together the buffalo sauce ingredients. Once the cauliflower are done, remove from the oven and brush with the buffalo sauce. Again, fully and evenly coat each piece.Put back into the oven and bake for a 5-7 minutes, until the sauce has mostly dried and the cauliflower is crispy. Remove from the oven, let cool, then enjoy!
