How to Make Sugar-Free Yogurt Cloud Cake
This cake is baked in a water bath to ensure a soft, moist, cloud-like texture.
Prepare the Pan
Preheat the oven to 325°F.
Lightly grease an 8-inch round cake pan.
Line the bottom and sides with parchment paper, allowing the paper to extend slightly above the rim.
Place the cake pan inside a larger baking dish or roasting pan.
Set aside while preparing the batter.
Make the Yogurt Base
Add egg yolks, Greek yogurt, sugar-free sweetener, vanilla extract, lemon juice, and lemon zest to a large bowl.
Whisk until smooth and creamy.
Sift all-purpose flour, cornstarch, and salt over the yogurt mixture.
Whisk gently just until smooth and no dry lumps remain.
Whip the Egg Whites
Add egg whites and cream of tartar to a clean, dry bowl.
Beat with an electric mixer until soft peaks form.
Continue beating until the egg whites become glossy and hold medium peaks.
Do not overwhip, as stiff dry egg whites are more difficult to fold into the batter.
Fold the Batter
Add one-third of the whipped egg whites to the yogurt base.
Fold gently with a spatula until mostly combined.
Add the remaining egg whites in two additions.
Fold slowly and gently until the batter is light and airy.
Do not overmix; a few small streaks of egg white are fine.
Bake the Cake
Pour the batter into the prepared cake pan.
Smooth the top gently with a spatula.
Pour hot water into the larger baking dish until it reaches about halfway up the sides of the cake pan.
Bake for 45 to 55 minutes, until the top is lightly golden and the center has a gentle jiggle.
Turn off the oven, crack the door open slightly, and let the cake rest inside for 15 minutes.
Remove the cake from the water bath and let it cool completely at room temperature.
Chill and Serve
Refrigerate the cake for at least 2 hours for the best creamy texture.
Dust with powdered sugar-free sweetener.
Garnish with fresh berries, sugar-free whipped cream, or extra lemon zest if desired.
Slice into 8 portions and serve chilled.
Texture and Flavor
This yogurt cloud cake has a light, soft, soufflé-like texture with a delicate golden top and creamy center. The whipped egg whites create an airy structure that feels almost weightless.
The flavor is bright and refreshing, with Greek yogurt providing a tangy creaminess and fresh lemon juice and zest adding vibrant citrus notes. The sugar-free sweetener provides gentle sweetness without overpowering the delicate flavors.
Served chilled, it feels like a light, elegant dessert that is perfect for any occasion.
Tips for the Best Results
A few small details can help your yogurt cloud cake turn out perfectly.
Use Thick Greek Yogurt
Use thick Greek yogurt for the creamiest texture and the most stable cake. Thin yogurt can make the batter too loose.
Bring Eggs to Room Temperature
Bring eggs to room temperature before separating them for easier whipping. Cold eggs whip less easily.
Use a Clean Bowl
Use a clean, dry, grease-free bowl for the egg whites so they can reach full volume. Any grease can prevent proper whipping.
Fold Gently
Fold egg whites gently to preserve air and create the signature cloud-like texture. Overmixing can deflate the batter.
Use a Water Bath
Bake the cake in a water bath to help it cook gently and remain soft and moist. This prevents cracking and ensures even baking.
Expect Some Shrinking
A small amount of shrinking as the cake cools is normal. This is typical for soufflé-style cakes.
Cool Slowly
Let the cake cool slowly in the oven before removing it to reduce cracking. This helps the texture set properly.
Chill Before Slicing
Chill the cake before slicing for the neatest portions and creamiest texture. This firms up the cake for clean cuts.
Easy Variations
This recipe is easy to customize with different flavors and toppings.
Add Blueberries
Fold 1/2 cup of fresh blueberries into the batter for a lemon-blueberry version.
Add Raspberries
Top with fresh raspberries before serving for a bright, colorful twist.
Add Orange Zest
Replace lemon zest with orange zest for a citrus variation.
Make It Dairy-Free
Use dairy-free Greek yogurt for a dairy-free version.
Add Vanilla Bean
Use vanilla bean paste instead of vanilla extract for a deeper vanilla flavor.
Serving Ideas
This yogurt cloud cake is best served chilled. A dusting of powdered sugar-free sweetener and fresh berries makes it look and taste extra special.
Sugar-free whipped cream adds richness, while extra lemon zest enhances the citrus aroma. It is perfect for afternoon tea, brunch, holiday gatherings, or any time you want a light, refreshing dessert.
Storage Tips
Store the cake covered in the refrigerator for up to 3 days.
Keep the cake covered with plastic wrap or transfer individual slices to an airtight container.
For the best texture, serve it chilled. The flavor becomes more vibrant as it sits.

Common Mistakes to Avoid
A few simple mistakes can affect the texture of this yogurt cloud cake.
Using Thin Yogurt
If the yogurt is too thin, the batter can be too loose. Use thick Greek yogurt for best results.
Overwhipping the Egg Whites
Overwhipped egg whites become stiff and dry, making them difficult to fold. Beat until glossy medium peaks form.
Overmixing the Batter
Fold the egg whites gently. Overmixing can deflate the light, airy texture.
Skipping the Water Bath
The water bath is essential for a soft, moist texture. Skipping it can cause cracking and uneven baking.
Not Chilling Long Enough
The cake needs at least 2 hours to set. Chilling longer gives cleaner slices and a creamier texture.
