Preheat your oven to 350°F.
In a large mixing bowl, combine the crab meat, cheddar cheese, mayonnaise, green onions, garlic powder, Worcestershire sauce, and black pepper. Mix until well combined.
Using a spoon, scoop out small portions of the mixture and form them into balls, about 1 inch in diameter.
Roll each ball in the crushed cornflakes until fully coated.
Place the coated crab balls on a baking sheet lined with parchment paper, spaced about 2 inches apart.
Bake in the preheated oven for 15-20 minutes, or until golden brown and crispy.
Remove from the oven and let cool for a few minutes before serving.
