Preheat your oven to 350°F (175°C).

Grease a muffin tin with cooking spray or oil.

In a mixing bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until smooth.

Stir in the shredded cheese and diced ham until evenly combined.

Pour the egg mixture into the prepared muffin tin, filling each cup about 3/4 full.

Place the muffin tin in the preheated oven and bake for 18 minutes.

Let the bites cool for a few minutes before gently removing them from the tin.

Serve warm or let them cool completely before storing.
