Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper.

A moderate oven temperature is important. Cloud bread is delicate, so excessive heat can brown the outside too quickly while affecting the fluffy structure inside.

Place the egg whites in a completely clean, dry bowl. Using a hand mixer or stand mixer, beat them until they become frothy and begin forming soft foam.

Make sure there is no egg yolk mixed into the whites. Even a small amount of fat can make it difficult to achieve the volume you need.

Slowly add the sugar while continuing to beat the egg whites.

Don't dump everything in at once. Adding it gradually gives you a smoother, more stable meringue. Keep mixing until the whites become glossy and hold firm peaks.

Sift the cornstarch into the mixture and gently incorporate it.

At this point, you can also add vanilla extract or a few drops of food coloring if you want to give your cloud bread some personality.

Continue whipping just until the mixture is thick, glossy, and able to hold its shape.

Spoon the mixture onto the parchment-lined baking sheet.

Instead of spreading it flat, pile it into a rounded mound. Use the back of a spoon or spatula to create soft, uneven peaks so it resembles a fluffy cloud.

This is also the fun part if you're making it for kids. You can experiment with different shapes and colors.

Bake for approximately 20–25 minutes, keeping an eye on it toward the end.

The outside should look lightly golden and set. Baking times can vary depending on your oven and the size of your cloud.

Let it cool for a few minutes before carefully lifting it from the parchment.
