Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and lightly grease it.
In a mixing bowl, combine cheddar, mozzarella, cream cheese, and diced jalapeños.
Add flour, garlic powder, onion powder, salt, and pepper; mix until fully combined.
Using a tablespoon scoop or your hands, shape the mixture into small balls.
Dip each ball into the beaten eggs, then roll in breadcrumbs to coat.
Arrange coated bites on the baking sheet.
Lightly spray with cooking spray for extra crispiness.
Bake for 12–15 minutes or until golden.
Let cool slightly before serving.
