Wash the broccoli and finely chop the florets into small, pea-size pieces; blanch in boiling water for 1 to 2 minutes if you prefer a softer center, then drain well and pat completely dry.

In a large mixing bowl, combine the chopped broccoli, shredded cheddar cheese, breadcrumbs, garlic powder, onion powder, salt, and pepper.

Add the eggs (or prepared flax eggs) to the bowl and mix thoroughly until the mixture is cohesive and holds together when pressed in your hand.

Scoop about 1 tablespoon of the mixture at a time and roll into firm bite-size balls, pressing gently so they hold their shape; repeat until all the mixture is used.

Preheat the air fryer to 375°F (190°C) for 3 to 5 minutes.

Lightly grease or spray the air fryer basket with cooking spray, then arrange the broccoli cheddar poppers in a single layer with a little space between each one.

Air fry at 375°F (190°C) for 10 to 12 minutes, shaking the basket or turning the poppers once halfway through, until the crumbs are golden brown and the cheese is melted.

Remove the poppers from the air fryer and let them cool for 3 to 5 minutes to firm slightly before serving warm with your favorite dipping sauce.
