Preheat your oven to 350°F. Grease your muffin tray well with cooking spray. This helps the egg bites come out easily. Set the tray aside while preparing the filling.

Heat butter in a frying pan over medium heat. Add onion and peppers. Cook for three to four minutes. Stir often until soft, sweet, and lightly golden.

Add diced ham to the cooked vegetables. Stir for one minute. This warms the ham and blends the flavors nicely. Your kitchen will smell warm and delicious.

Crack eggs into a large bowl. Add milk, salt, pepper, and garlic powder. Whisk very well until smooth, light, and slightly frothy for fluffy bites.

Add cooked ham mixture into the egg bowl. Stir in shredded cheddar cheese. Mix gently so everything spreads evenly. Each bite should have plenty of tasty filling.

Pour the egg mixture into prepared muffin cups. Fill each cup about three-fourths full. This gives space for rising while baking in the hot oven.

Place the tray in the oven. Bake for about twenty minutes. The tops should look puffed and set. A toothpick inserted should come out clean.

Let the egg bites cool for five minutes. Carefully remove them from the tray. Sprinkle parsley on top. Serve warm and enjoy your homemade breakfast bites.
