Preheat your oven to 350°F (175°C). Lightly grease a muffin tin or silicone muffin cups. Yes, this is where the magic happens.
Whisk the eggs with milk, salt, pepper, and garlic powder until the mixture looks smooth and not scary. If you can’t whisk without a tiny victory dance, you’re doing it right.
Stir in the cheese, peppers, and onions. The combo should look bright and a little cheesy, in the best possible way.
Pour the mixture into the muffin cups, filling about 3/4 full. Don’t overfill—these aren’t surprise omelets, they’re bite-sized champs.
Bake for 18–22 minutes, until the tops are set and a toothpick comes out clean. If your oven runs hot, start checking at 16 minutes.
Cool for a few minutes, then run a knife around the edges and pop them out. They’ll be light as air and ready to conquer your cravings.
