Preheat the oven to 375°F and line a baking sheet with parchment paper.
Place the florets into a large bowl. Drizzle in the oil and toss the cauliflower to coat all over. Pour in the flour and garlic powder and toss again to coat; then add the milk and breadcrumbs and toss to coat all over.
Lay on the prepared baking sheet with space between each one and bake for 15 minutes until crispy.
When the cauliflower is almost done baking, mix the melted butter and hot sauce together until it is well combined.
Dip each floret into the sauce and place it back onto the baking tray or on a wire rack to get the excess sauce off. Serve and enjoy.
