Place cauliflower florets in a separate large bowl. Dip each floret into the egg, then almond flour mixture, then egg again and flour.
Preheat the air fryer to 350 F according to manufacturer instructions (usually it’s 4-5 minutes). I used my Cosori 5.8 quart air fryer.
Once the air fryer is preheated, transfer the cauliflower into the basket (spray the basket lightly with oil or use air fryer basket liners), and spray more oil on top of the florets too.
Set the timer for 14 minutes, shaking the basket at the 7-minute mark.
You’ll need to do this in 2-3 batches depending on the size of your air fryer. The florets should be crispy, lightly golden brown, and cooked through.
Meanwhile, prepare another large bowl with hot sauce and melted butter, and set aside.
Once all the cauliflower is cooked, add it to a hot sauce bowl and toss until fully coated.
Return to the air fryer for 4 minutes. You can skip the last step and drizzle the cauliflower with hot sauce before serving.
