In a large mixing bowl, whisk together all of the dry ingredients (flour, onion and garlic powder, ground paprika, salt, and black pepper).
Whisk in the plant milk until smooth. The mixture should be slightly thinner than pancake batter. Add in an extra splash of plant milk if needed to achieve the right consistency.
Add the cauliflower florets into the bowl and toss to coat. It's ok if the cauliflower isn't 100% coated, as long as the batter is evenly distributed across all the florets. (I like to use my hands to really get the batter into the crevices of the cauliflower but this is optional.)
