Step 1: Prepare the Cauliflower : Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper. In a large bowl, whisk together flour, water (or milk), garlic powder, paprika, salt, and pepper into a smooth batter. Toss cauliflower florets into the batter until evenly coated. Spread the coated cauliflower evenly on the baking sheet.
Step 2: Bake the Cauliflower : Bake for 20 minutes, flipping halfway through for even crispiness. Meanwhile, warm the buffalo sauce with butter (if using) in a small pan. After 20 minutes, remove cauliflower, brush or toss with the buffalo sauce mixture, and return to the oven for another 10 minutes until crispy and caramelized. (Alternative: Air fry at 400°F for 15–18 minutes, shaking halfway through.)
Step 3: Make the Ranch Dressing : In a small bowl, whisk together mayo, sour cream (or yogurt), milk, garlic powder, onion powder, dill, parsley, salt, and pepper. Taste and adjust seasoning as needed. Chill until ready to serve.
Step 4: Assemble the Wraps : Warm tortillas in a skillet for 10–15 seconds on each side until soft and pliable. Lay a tortilla flat and spread a spoonful of ranch dressing in the center. Add shredded lettuce, carrots, red cabbage, cucumber, and onions. Place a few pieces of buffalo cauliflower on top. Drizzle with extra ranch dressing. Roll up tightly, tucking in the sides as you go. Slice in half if desired.
Step 5: Serve : Serve immediately while the cauliflower is warm and crispy. Enjoy with extra ranch or buffalo sauce on the side for dipping.
