Cloud Cake is a delicate sponge cake made with whipped egg whites for a light, airy texture. It’s simple, elegant, and perfect with powdered sugar and fresh berries.
Pre-heat the oven to 350°F. Line just the bottom of an 8-inch round pan with parchment paper. Do not grease the sides; this helps the cake climb upward.
Whisk together the cake flour, baking powder, and salt. Set aside for later.
In a large bowl, whisk egg yolks with ½ cup of sugar until pale and slightly thick. Slowly whisk in the canola oil, then milk, and then vanilla.
Sift the dry ingredients into the yolk mixture. Stir gently just until smooth and lump-free. The batter should be smooth. (Be sure not to overmix.)
In a clean bowl, beat egg whites until foamy. Gradually add the remaining ¼ cup of sugar. Beat until soft, glossy peaks form. Be sure not to overwhip; the peaks should bend slightly.
Fold in ⅓ of the egg whites into the batter to loosen it. Gently fold in the remaining whites. Use a wide spatula and go in slow, lifting motions.
Pour batter into the pan and tap on the counter once lightly. This will help release large air bubbles.
Bake for 40-45 minutes, or until the top springs back and a skewer comes out clean. A few moist crumbs are okay.
Immediately invert the pan when you remove the cake from the oven. Leave the pan inverted until the cake is cooled completely, around 1 ½ -2 hours. This will prevent collapse and keep the cake cloud-soft. I like to use two small jars and place the pan upside down using the rim of the pan. This way it keeps the cake off any surface to cool.
Once the pan is completely cool, run a thin knife around the edge to release it from the sides of the pan. Remove the cake and peel off the parchment paper.
Right before serving, dust the cake with powdered sugar and/or serve with fresh berries.
Notes
Let your eggs come to room temperature before starting. They whip better and create more volume.
Make sure your bowl and beaters are completely clean before whipping egg whites. Any grease can prevent proper peaks.
Stop at soft peaks. They should look glossy and gently droop.
Fold slowly. Scoop from the bottom and lift. Don’t stir.
Tap the pan lightly once to remove large air pockets without deflating the batter.
Be patient during cooling. Leaving the cake upside down until completely cool is what keeps it cloud-soft.
