Preheat your oven at 350-degrees F.
Place an egg in each round of a muffin tin. You can make one or a dozen as you need.
You don't have to grease them or use cake liners, just set them in the muffin round.
Bake at 350*F for 30 mins.
Plunge the muffin tin under cold running water to cool down the eggs.
Then I lifted the eggs when they weren't as hot and put them in a bowl under the cold running water to continue cooling down the eggs. It was easier for me to handle by transferring them.
Sorry the photo isn't clearer. These centers are beautifully hard-cooked but the glare of the overhead lights spoiled my shot. Anyway, they are perfectly cooked on the inside. No more wondering if you've boiled them enough in the water on the stove.
If you have the time, this is a good way to get perfect hard-boiled eggs, by baking them.
