Preheat your oven to 450°F (230°C), ensuring it's fully heated before baking for best results. Line a baking tray with either a silicone baking mat or foil lightly greased with oil to prevent sticking.

Cut the cauliflower into florets, discarding the leaves and the thick central stalk. Aim for bite-sized pieces that resemble classic wings in shape and size. A small portion of the stem can be left intact to help grip the pieces if desired.

In a large mixing bowl, combine the flour, cornstarch, garlic powder, sea salt, black pepper, and plant-based milk. Whisk until smooth and lump-free. If the consistency appears too thick, stir in a splash of extra milk; if it’s too thin, add a touch more flour. In a separate bowl, place the seasoned panko breadcrumbs, and position it beside the batter bowl for easy access.

Toss all the cauliflower pieces into the batter and stir gently with a spatula or spoon until they are completely coated. Working in batches, transfer the battered florets into the breadcrumb bowl, ensuring each piece is thoroughly covered before placing it on the prepared baking sheet. Make sure to leave enough space between each piece to allow for even browning.

Slide the tray into the hot oven and bake for 22 minutes until the coating becomes crisp and golden. Meanwhile, prepare the BBQ sauce. If using a store-bought variety, it can be slightly thinned with a bit of water. Warm the sauce in a small pot over the stove or in a microwave-safe bowl until heated through, then allow it to cool slightly before coating the wings.

Once the wings are baked, remove them from the oven and transfer them into a large bowl. Pour the warm BBQ sauce over the wings and use a spatula to gently mix until fully coated. Alternatively, you can brush the sauce over each piece individually if you prefer a more even glaze.

Place the sauced wings back on the baking tray and return them to the oven. Bake for an additional 5 minutes to allow the sauce to set and caramelize slightly.

Remove from the oven and garnish immediately with freshly sliced scallions. Serve hot and enjoy every bite.
