Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a silicone baking mat.
Steam the broccoli florets until tender, about 5-7 minutes. Allow them to cool and then chop finely.
In a mixing bowl, combine the chopped broccoli, shredded cheddar cheese, egg, almond flour, garlic powder, onion powder, salt, and black pepper. Stir until well combined.
Using a spoon, scoop out the mixture and form small rounds, placing them on the prepared baking sheet. Flatten slightly if desired.
Lightly spray or brush the tops of the rounds with cooking spray or oil for a golden finish.
Bake in the preheated oven for 15-20 minutes, or until the rounds are firm and the tops are lightly browned.
Remove from the oven and let them cool for a few minutes before serving.
