Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper for easier cleanup.
In a large mixing bowl, whisk together the flour, garlic powder, paprika, salt, and black pepper until well combined.
Gradually add water to the dry ingredients, whisking until you have a smooth batter. The consistency should be thick but pourable.
Dip each cauliflower floret into the batter, ensuring it is well coated, then let any excess batter drip off.
Roll the coated florets in breadcrumbs until they are fully covered. Place them on the prepared baking sheet in a single layer.
Drizzle the olive oil over the cauliflower bites for added crispiness.
Bake in the preheated oven for 25 minutes or until golden brown and crispy, flipping halfway through for even cooking.
Once done, remove from the oven and let cool slightly before serving.
Serve with your choice of dipping sauce and enjoy!
