Preheat your oven to 450°F and line two baking sheets with parchment paper. Mix together flour, cornstarch, garlic powder, onion powder, smoked paprika, cayenne, salt, and black pepper in a large bowl. This dry mixture is what creates that crispy coating that sticks to every floret without getting soggy.
Beat the 2 eggs in a separate shallow bowl until they're fully combined. Grab your cauliflower florets and pat them completely dry with paper towels—this step is crucial for getting them crispy. Wet cauliflower won't crisp up properly, so don't rush this part.
Dip each floret into the egg mixture, making sure it's fully coated on all sides. Then immediately roll it in the flour mixture, pressing gently so the coating adheres. You'll want that flour mixture clinging to every surface for maximum crispiness.
Arrange the coated florets on your prepared baking sheets in a single layer without crowding. Make sure they're not touching each other, or they'll steam instead of crisp up. I always leave about an inch between each piece for even air circulation.
Bake at 450°F for 20-22 minutes until the coating turns golden brown and the edges get crispy. The buffalo cauliflower should look almost caramelized on the outside—that's when you know it's ready. Don't panic if it looks a little darker than you expected because that color means crispiness.
While the florets bake, whisk together your hot sauce and melted butter in a medium bowl. Warm this mixture gently—it doesn't need to be piping hot, just combined and ready. Some people like extra buttery sauce, so taste and adjust to your preference.
Remove the baked florets from the oven and transfer them to a large bowl while they're still hot. Pour the buffalo sauce over them and toss gently until every piece is coated. Serve immediately because this buffalo cauliflower recipe tastes best when it still has that warm, crispy texture.
