Preheat and prep: Set your oven to 450°F (230°C).
Line a baking sheet with parchment and lightly grease it to prevent sticking.
Separate the eggs: Carefully separate whites from yolks into two bowls. Keep each yolk intact in its own small cup or on a spoon so it’s easy to place later.
Whip the whites: Add the cream of tartar to the whites. Beat with a hand mixer or stand mixer on medium-high until stiff peaks form.
The foam should stand up without collapsing.
Fold in flavor: Gently fold in the shredded cheese, Parmesan, garlic powder, onion powder, paprika or pepper, salt, and chives. Use a spatula and a light hand to avoid deflating the whites.
Shape the clouds: Divide the mixture into four mounds on the baking sheet. Use the back of a spoon to make a small well in the center of each mound.
First bake: Bake for 3–4 minutes until they’re lightly golden and set on the outside.
Add the yolks: Remove the tray and gently slide one yolk into each well.
Final bake: Return to the oven for 3–5 minutes, depending on how runny you like the yolk.
Shorter time for runny, longer for jammy or set.
Serve: Let the clouds sit for 1–2 minutes. Sprinkle with extra chives or a pinch of pepper. Serve warm.
