Pat cauliflower florets dry using paper towels and reserve.

Place the flour in a shallow bowl.

In a medium saucepan, warm the milk and cornstarch over moderately high heat; let it cook for about 5 minutes, until slightly thickened: let it cool and transfer the mixture to another shallow bowl.

In a third shallow bowl, place breadcrumbs.

Dip the cauliflower florets in the flour, then into the milk mixture; roll them over the breadcrumbs.

Brush cauliflower florets with olive oil and transfer them to the Air Fryer cooking basket.

Cook at 400 degrees F for about 10 minutes, shaking the basket halfway through the cooking time.

To make Buffalo sauce, melt the butter in a saucepan over medium-high heat; turn the heat to a simmer and add in the remaining sauce ingredients. Cover and continue to simmer, until cooked through.

Pour the sauce over air-fried cauliflower florets and serve immediately.

Bon appétit!
