Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a bowl, whisk together the flour, plant-based milk, garlic powder, smoked paprika, salt, and pepper until smooth.
Dip each cauliflower floret into the batter, ensuring an even coat. Then, dredge in panko breadcrumbs and place on the prepared baking sheet.
Bake for 25–30 minutes, flipping halfway through, until the cauliflower is crispy and golden brown.
In a small bowl, whisk together vegan mayonnaise, sweet chili sauce, sriracha, lime juice, and optional maple syrup until smooth.
Once baked, toss the crispy cauliflower with the sauce or drizzle it on top.
Garnish with sliced spring onions and a sprinkle of white and black sesame seeds before serving. Serve and enjoy!
