Preheat your oven to 375°F and grease a 12-cup muffin tin very well.
Whisk together eggs, heavy cream, salt, and pepper in a large bowl until well combined.
Divide the crumbled bacon, cheese, and green onions between the muffin cups.
Pour the egg mixture evenly over the fillings, filling each cup about ¾ full.
Bake for 20-25 minutes until the eggs are set and slightly golden on top.
