Fluffy Yogurt Cloud Cake

Last spring, my neighbor brought over this impossibly light cake after I mentioned I was craving something sweet but not heavy. One bite and I understood why she called it a cloud cake—so airy it practically floats off the plate. The Greek yogurt keeps it moist while still being feather-light, and that hint of lemon makes everything taste bright and cheerful.

I made this for my mothers birthday instead of the usual dense chocolate cake, and honestly, it was the hit of the party. Everyone kept asking how I got it so tall and fluffy without any heavy cream or butter. My aunt actually leaned over and whispered that she needed the recipe immediately because it reminded her of the delicate pastries she had in Paris years ago.

Ingredients

• 1 cup all-purpose flour: Provides just enough structure to hold all that air without becoming heavy or dense
• 1/2 cup cornstarch: The secret weapon for tenderness—makes the crumb impossibly soft and delicate
• 1 1/2 tsp baking powder: Gives an extra lift alongside the egg whites for maximum height
• 1/4 tsp salt: Balances sweetness and enhances the lemon flavor
• 4 large eggs, separated: Beaten whites create the cloud-like texture while yolks add richness
• 3/4 cup granulated sugar, divided: Sweetens without weighing down the delicate structure
• 1/2 cup vegetable oil: Keeps the cake incredibly moist for days
• 1 cup full-fat Greek yogurt: Adds tang and creaminess while keeping things light
• 1 tsp vanilla extract: Rounds out the flavors and adds warmth
• Zest of 1 lemon: Brightens everything and cuts through the richness
• Powdered sugar for dusting: Makes it look elegant and adds a finishing touch of sweetness
• Fresh berries for serving: Perfect complement to the light cake

Instructions

Preheat your oven to 325°F and line an 8-inch round pan:

Line the bottom with parchment paper but leave the sides ungreased—this helps the cake climb and rise properly.

Whisk together your dry ingredients:

Combine flour, cornstarch, baking powder, and salt in a bowl, then set aside.

Beat the egg yolks with half the sugar:

Whisk until the mixture turns pale and creamy, then add oil, yogurt, vanilla, and lemon zest until smooth.

Fold in the dry ingredients:

Gently incorporate the flour mixture until just combined—do not overmix or you will lose all that air you just created.

Beat the egg whites until stiff peaks form:

Start on medium speed until soft peaks appear, then gradually add the remaining sugar and beat until glossy and stiff.

Fold the whites into the batter in three additions:

Start with one third to lighten the mixture, then gently fold in the rest—be gentle and patient here.

Pour and smooth the batter:

Transfer to your prepared pan and use a spatula to create an even surface.

Bake for 40–45 minutes:

Wait until the cake is set and a toothpick comes out clean—do not open the oven too early.

Cool with patience:

Let it rest in the pan for 10 minutes before running a knife around the edge and inverting onto a rack.

My daughter asked if she could help make this for her school bake sale, and I loved watching her face light up as the egg whites transformed into glossy peaks. She insisted on doing the dusting herself and was so proud when people kept coming back for seconds. Now it is our go-to special occasion cake.

Making It Ahead

This cake is actually fantastic the next day because the flavors have time to meld and develop. Wrap it tightly once completely cooled, and it stays perfectly moist for up to two days at room temperature.

Serving Suggestions

While powdered sugar and berries are classic, a dollop of Greek yogurt sweetened with honey takes it to another level. I have also served it with macerated strawberries or a simple lemon glaze when I want something extra.

Getting The Perfect Rise

The height of this cake comes entirely from properly beaten egg whites and gentle folding technique. Make sure your mixing bowl is completely clean and dry before beating the whites—even a drop of fat can prevent them from reaching their full potential.

• Use a metal or glass bowl for beating egg whites
• Fold with a spatula using a gentle figure-eight motion
• Stop folding as soon as you no longer see white streaks

This cake is proof that sometimes the most elegant desserts come from the simplest ingredients and a little patience.

Recipe FAQs

→ What makes this cake so light and fluffy?

The secret lies in beating egg whites to stiff peaks and gently folding them into the batter. This technique incorporates air pockets throughout, creating that signature cloud-like texture. The Greek yogurt also adds moisture without weighing down the crumb.

→ Can I use regular yogurt instead of Greek yogurt?

Greek yogurt is recommended because its thicker consistency provides better structure and richness. Regular yogurt contains more water, which could affect the texture. If substituting, consider straining regular yogurt overnight to remove excess whey.

→ Why shouldn't I grease the sides of the pan?

Leaving the sides ungreased allows the batter to climb higher as it bakes, helping the cake rise properly. The ungreased surface gives the batter something to grip onto, resulting in better volume and a taller, lighter cake.

→ How do I know when the cake is done baking?

Insert a toothpick into the center—it should come out clean or with just a few moist crumbs. The cake should feel set and spring back slightly when touched gently. Visual cues include a golden top and slight pulling away from the pan edges.

→ Can I make this cake in advance?

This cake tastes best the same day but can be stored in an airtight container for up to 2 days. The texture remains remarkably light thanks to the yogurt and egg white technique. For serving, try chilling briefly—the cool temperature enhances the refreshing, airy quality.

→ What can I serve with this cake?

A dusting of powdered sugar adds elegance and subtle sweetness. Fresh berries like strawberries, raspberries, or blueberries complement the light, creamy flavors beautifully. A dollop of whipped cream or a drizzle of fruit coulis also works wonderfully for special occasions.
