Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a bowl, mix flour and plant-based milk to form a smooth batter.
In another bowl, combine breadcrumbs, garlic powder, paprika, salt, and pepper.
Dip each cauliflower floret into the batter, then coat with the breadcrumb mixture.
Place coated florets on the baking sheet and bake for 25-30 minutes until golden and crispy.
While the cauliflower bakes, prepare the sauce by mixing vegan mayonnaise, sweet chili sauce, sriracha, and lime juice in a small bowl.
Remove the cauliflower from the oven and toss with the sauce before serving.
