In a large bowl, whisk together all-purpose flour, garlic powder, onion powder, baking powder, salt, and ground black pepper until well-combined. Set aside.

In a separate bowl, mix together oat milk and Louisiana-style hot sauce until smooth.

Pour vegetable oil into a deep skillet to about 2 inches deep and heat over medium-high heat until ready for frying.

Dip each cauliflower floret into the oat milk mixture, then coat it lightly with the flour mixture.

Fry coated cauliflower florets in small batches for 1-2 minutes on each side until golden brown.

Remove fried cauliflower and drain on paper towels. Serve warm.
