Cloud Cake (Butt Cake) — A Recipe You Can Make at Home in an Oven

Prepare all the ingredients; mix 65 grams of flour with 10 grams of cornstarch together.

Heat 60g of oil to about 60-70 degrees Celsius until it starts to ripple and small bubbles appear. Then turn off the heat. (Note: Do not use peanut oil, as its flavor is too strong.)

Combine the oil with the mixed cake flour and cornstarch, stirring until smooth and free of lumps.

Add 60 grams of milk and stir until thickened.

Separate five to six eggs, separating the yolks and whites. Add the yolks to the batter you just prepared. If the egg whites weren't taken directly from the refrigerator, it's recommended to chill them slightly in the refrigerator; this will make the whipped egg whites smoother.

The mixed batter should look like this: smooth and free of lumps.

First, whip the egg whites at medium-low speed, then add 40 grams of sugar in three batches.

Whip the egg whites until they form stiff peaks that don't flow like liquid; don't over-whip, or the cake surface will crack.

First, add about one-third of the egg whites to the egg yolk mixture, and use a folding motion to gently fold the egg yolk mixture into the egg whites, avoiding overmixing.

Continue using the same method to pour the remaining egg yolks into the egg whites and mix well. Be careful not to use small air bubbles; it's normal for some to rise to the surface.

If your mold is a removable piece, remember to wrap it with several layers of aluminum foil. I wrapped mine with three layers. As for the inner baking paper, I was too lazy, so I just crumpled it up and stuffed it in.

Pour the batter from a height so that it is distributed more evenly.

If the surface is uneven, use a large bamboo skewer to gently stir it to remove large air bubbles, then shake it again. Pour the prepared batter into a container that can hold about 1 cm of water.

Bake at 140 degrees Celsius (325 degrees Fahrenheit) for 80 minutes, using both top and bottom heat. Since the temperature of a home oven is somewhat unpredictable, I'll just use 150 degrees Celsius.

Keep an eye on the time; my oven takes about an hour to bake, which should be about right.
