Preheat the oven to 425 degrees Fahrenheit and line a baking sheet with parchment paper.
In a medium sized bowl, whisk together the chickpea flour, garlic and onion powders, salt, and pepper. Add the water and mix well.
Toss the cauliflower pieces in the batter until every piece is properly coated.
Coat the parchment paper in oil. Place the cauliflower pieces onto the baking sheet, making sure that the pieces do not overlap. Do not pour the cauliflower pieces from the bowl--you do not want the extra batter on the baking sheet!
Bake for 25 minutes.
While the cauliflower is baking, mix the hot sauce and melted butter together in a medium sized bowl.
After 25 minutes in the oven, remove the cauliflower wings and coat them in the hot sauce mixture. Return the cauliflower pieces to the baking sheet.
Bake the wings for another 15-25 minutes.
While the wings are in for their second baking, mix together all the ingredients for the garlic dip.
Serve the wings fresh out of the oven with the garlic dip.
