admin1 Keto Cloud Cake is a light, airy, fluffy dessert that resembles a cross between angel food cake and a soft sponge cake. It is low in carbohydrates, gluten-free, and perfect for anyone following a ketogenic lifestyle. The secret to its cloud-like texture is properly whipped egg whites, which create volume without requiring traditional flour.

Total Time
Approximately 1 hour
Ingredients
6 large eggs, separated into whites and yolks
120 g (1 cup) powdered erythritol or preferred keto sweetener, divided
120 g (4 oz) cream cheese, softened
1 teaspoon vanilla extract
1 teaspoon lemon juice
1 teaspoon cream of tartar
30 g (¼ cup) almond flour, sifted
¼ teaspoon salt
2 tablespoons unsalted butter, melted and cooled
Optional toppings:
Whipped heavy cream
Fresh berries in moderation
Sugar-free chocolate shavings
Powdered keto sweetener for dusting
Equipment Needed
Large mixing bowl
Medium mixing bowl
Electric hand mixer or stand mixer
Rubber spatula
8-inch round cake pan or springform pan
Parchment paper
Fine sieve for sifting almond flour
Cooling rack
Step 1: Prepare the Oven and Pan
Preheat the oven to 160°C (320°F).
Line the bottom of an 8-inch cake pan with parchment paper. Lightly grease the sides of the pan with butter or a neutral oil. Proper preparation prevents sticking and helps the delicate cake release cleanly after baking.
Step 2: Separate the Eggs Carefully
Separate the eggs while they are cold because the yolks are firmer and less likely to break.
Place the egg whites into a completely clean and dry large mixing bowl.
Place the yolks into a separate medium bowl.
Even a tiny amount of yolk in the whites can prevent them from whipping properly, so take your time with this step.
Step 3: Prepare the Egg Yolk Mixture
Add the cream cheese to the bowl containing the egg yolks.
Add half of the powdered sweetener.
Pour in the vanilla extract.
Add the melted butter.
Mix everything together until completely smooth and creamy.
Once smooth, sift the almond flour directly into the mixture.
Mix again until no lumps remain.
The batter should be silky, thick, and uniform in color.
Step 4: Whip the Egg Whites
Add the cream of tartar, lemon juice, and salt to the bowl containing the egg whites.
Using an electric mixer, begin beating on medium speed.
When the whites become foamy, gradually add the remaining sweetener a little at a time.
Continue beating until stiff glossy peaks form.
The peaks should stand upright when the beaters are lifted.
Avoid overbeating because excessively whipped whites can become dry and difficult to fold into the batter.
Step 5: Fold the Mixtures Together
Take approximately one-quarter of the whipped egg whites and stir them into the yolk mixture.
This first addition lightens the batter and makes folding easier.
Next, add the remaining egg whites in three separate additions.
Using a rubber spatula, gently fold by cutting down through the center of the batter, sweeping across the bottom, and bringing the mixture up over the top.
Rotate the bowl slightly after each fold.
Continue folding only until no large white streaks remain.
The goal is to preserve as much air as possible because those trapped air bubbles create the cake’s signature cloud-like texture.
Step 6: Fill the Cake Pan
Transfer the batter into the prepared cake pan.
Spread it gently and evenly with a spatula.
Tap the pan very lightly on the counter once or twice to remove any extremely large air pockets.
Do not tap excessively because you do not want to deflate the batter.
Step 7: Bake the Cake
Place the cake in the center rack of the preheated oven.
Bake for 30–35 minutes.
The surface should become lightly golden and spring back when touched gently.
Avoid opening the oven during the first 25 minutes of baking because sudden temperature changes can cause the cake to collapse.
If the top browns too quickly, loosely place a sheet of foil over the pan during the final portion of baking.
Step 8: Cool Properly
Remove the cake from the oven.
Allow it to cool in the pan for approximately 15 minutes.
Run a thin knife around the edge if necessary.
Carefully remove the cake from the pan and transfer it to a cooling rack.
Allow it to cool completely before slicing.
The texture will continue to stabilize during cooling.
Step 9: Serve
Serve plain for a simple keto dessert or add keto-friendly toppings.
A layer of lightly sweetened whipped cream pairs beautifully with the airy texture.
A few raspberries, strawberries, or blueberries can add color and freshness while keeping carbohydrates relatively low.
The cake can also be dusted lightly with powdered keto sweetener for a bakery-style appearance.
Tips for Perfect Keto Cloud Cake
Room-temperature ingredients blend more smoothly and create a more consistent batter.
Always use a clean bowl when whipping egg whites.
Powdered sweetener works better than granulated sweetener because it dissolves more easily.
Fold gently and patiently to preserve volume.
Do not overbake, as the cake can become dry.
Allow the cake to cool completely before slicing to achieve the best texture.
Store leftovers in an airtight container in the refrigerator for up to 4 days.
For longer storage, wrap slices individually and freeze for up to 2 months.
