Light as a cloud and wonderfully soft, this Keto Cloud Cake is a dreamy low-carb dessert with an airy crumb and delicate vanilla flavor. Made with whipped egg whites, almond flour, and a keto-friendly sweetener, it has a beautifully fluffy texture without relying on traditional flour or a large amount of sugar. It’s perfect when you want something sweet, light, and satisfying without a heavy dessert.
Can This Keto Cloud Cake Support Weight Loss Goals?
This cake can fit into a balanced weight-conscious eating pattern when enjoyed in an appropriate portion. Almond flour and eggs provide fats and protein that can make a small slice more satisfying, while replacing traditional sugar helps reduce added carbohydrates. Because almond flour is calorie-dense, portion size still matters even though the cake is low in net carbs.
Does Keto Cloud Cake Fit a High-Protein Lifestyle?
Yes, this version can work well within a high-protein lifestyle because eggs provide a substantial amount of protein while almond flour contributes additional protein and fiber. Each serving contains approximately 3 g net carbs, making it suitable for many low-carb meal patterns. For a stronger protein boost, a small amount of unflavored or vanilla protein powder can replace part of the almond flour.

Short 3-Line Description
A light and fluffy keto cake with a delicate vanilla flavor and cloud-like crumb.
Almond flour and eggs create a satisfying low-carb dessert with protein-friendly ingredients.
Perfect for coffee breaks, celebrations, or a simple everyday keto treat.
📝 Ingredients
- 4 large eggs, separated and at room temperature
- ¾ cup finely ground almond flour
- ½ cup powdered monk fruit or erythritol sweetener, divided
- 2 tablespoons unsalted butter, melted and cooled
- 1 teaspoon pure vanilla extract
- ½ teaspoon baking powder
- ¼ teaspoon cream of tartar
- ¼ teaspoon salt
- 2 tablespoons unsweetened almond milk
Optional topping:
- 1 tablespoon powdered keto sweetener
- A few fresh berries
Note: Use finely ground almond flour rather than coarse almond meal for the softest crumb.
Directions
1. Prepare the Oven and Pan
Preheat the oven to 325°F (165°C).
Lightly grease an 8-inch round cake pan and line the bottom with parchment paper.
Avoid heavily greasing the sides if you want the batter to grip the pan as it rises.
2. Separate the Eggs
Separate the eggs carefully, placing the whites in a completely clean, dry mixing bowl.
Make sure there is no yolk or oil in the whites.
Allow the eggs to reach room temperature if they were refrigerated.
3. Prepare the Dry Ingredients
In a separate bowl, whisk together the almond flour, baking powder, salt, and half of the powdered sweetener.
Break up any visible almond flour lumps.
4. Make the Egg Yolk Mixture
In another bowl, whisk the egg yolks with the melted butter, almond milk, and vanilla extract.
Mix until smooth and creamy.
Add the dry ingredients and stir gently until a thick, smooth batter forms.
5. Whip the Egg Whites
Add the cream of tartar to the egg whites.
Using an electric mixer, beat on medium speed for 1–2 minutes until foamy.
Gradually add the remaining powdered sweetener while increasing to medium-high speed.
Continue beating for approximately 3–5 minutes, until the whites form stiff, glossy peaks.
High-protein tip: Egg whites provide additional protein without adding significant carbohydrates, so whipping them properly helps create both structure and volume.
6. Fold the Egg Whites
Add about one-third of the whipped egg whites to the yolk batter.
Fold gently with a rubber spatula to loosen the mixture.
Add the remaining whites in two additions, folding carefully from the bottom upward.
Stop as soon as the batter is evenly combined.
Do not stir aggressively, because deflating the egg whites will reduce the cloud-like texture.
7. Fill the Pan
Transfer the batter to the prepared cake pan.
Gently smooth the top with a spatula.
Tap the pan once or twice very lightly on the counter to remove only large air pockets.
8. Bake
Place the cake in the center of the preheated oven.
Bake at 325°F (165°C) for 30–35 minutes.
The top should be lightly golden, the center should spring back when gently touched, and a toothpick inserted in the middle should come out mostly clean.
9. Cool Gradually
Turn off the oven and leave the cake inside with the door slightly open for approximately 5 minutes.
Remove the cake and let it cool in the pan for 10 minutes.
Run a thin knife around the edges and carefully transfer the cake to a cooling rack.
10. Finish and Serve
Once completely cooled, dust the top lightly with powdered keto sweetener.
Slice into 8 portions using a sharp serrated knife.
Serve plain or with a small amount of unsweetened whipped cream and a few low-carb berries.

Yes, the cake can be prepared a day ahead and kept covered in the refrigerator.
How do I make the cake more chocolatey?
Replace 1 tablespoon of almond flour with 1 tablespoon of unsweetened cocoa powder for a mild chocolate version.
