Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
6 large eggs, separated
½ cup monk fruit sweetener, divided into two portions of ¼ cup each
½ cup unsweetened almond milk
¼ cup neutral oil (such as sunflower or light olive oil)
¾ cup cake flour or finely sifted all-purpose flour
1 tablespoon cornstarch
½ teaspoon cream of tartar
1 teaspoon vanilla extract
¼ teaspoon salt
Directions
Begin by preheating your oven to 150°C (300°F). Line the bottom of a round cake pan with parchment paper, and lightly grease the sides. Prepare a water bath by placing a larger pan filled with hot water on the lower rack of the oven.
In a medium bowl, whisk together the egg yolks, ¼ cup monk fruit sweetener, almond milk, oil, and vanilla extract until smooth and slightly pale. Sift in the flour and cornstarch, then mix gently until fully combined and lump-free.
In a separate clean bowl, beat the egg whites with salt and cream of tartar using an electric mixer. Once foamy, gradually add the remaining ¼ cup monk fruit sweetener. Continue beating until soft to medium peaks form. The meringue should be glossy and hold its shape without being too stiff.
Carefully fold one-third of the meringue into the yolk mixture to lighten it. Then gently fold in the remaining meringue in two additions, using a spatula and slow movements to preserve the air.
Pour the batter into the prepared pan and tap it lightly on the counter to remove large air bubbles. Place the cake pan into the water bath in the oven.
Bake for about 50 to 60 minutes, or until the top is lightly golden and the center is set but still slightly jiggly. Turn off the oven and leave the door slightly open, allowing the cake to cool gradually inside for 15 minutes.
Remove the cake, let it cool completely, then carefully release it from the pan. Serve as is or with a light dusting of powdered sugar substitute if desired.
Servings and timing
This recipe yields 8 servings. Preparation time is approximately 20 minutes, with a baking time of 50 to 60 minutes. Including cooling, the total time is about 1 hour and 30 minutes.
Variations
You can customize this cloud cake in several ways. Add a hint of citrus zest such as lemon or orange for a refreshing twist. For a richer flavor, replace almond milk with coconut milk. A touch of matcha powder can give the cake a subtle green tea flavor and color. If you prefer a slightly sweeter taste, you can adjust the level of sweetener to your liking without affecting the structure too much.
Storage/Reheating
Store the cake in an airtight container in the refrigerator for up to three days. Because of its delicate texture, it is best enjoyed fresh, but it will still taste good chilled. To serve, allow it to sit at room temperature for about 10 minutes. Reheating is not necessary, but if desired, you can warm slices very gently in a low-temperature oven for a few minutes.
FAQs
What makes this cake so fluffy?
The whipped egg whites create a meringue that traps air, giving the cake its signature light and airy texture.
Can I use a different sweetener?
Yes, other granulated sugar substitutes can work, but make sure they behave similarly to sugar in baking.
Is this cake gluten-free?
Not as written, but you can substitute the flour with a gluten-free blend for similar results.
Why did my cake collapse?
This can happen if the meringue is overmixed or if the cake cools too quickly.
Can I skip the water bath?
The water bath helps regulate temperature and prevents cracking, so it is highly recommended.
How do I know when it’s done?
The top should be lightly golden, and the center should jiggle slightly but not be liquid.
Can I make this dairy-free?
Yes, it already uses almond milk, making it naturally dairy-free.
What pan size works best?
A standard 7- or 8-inch round cake pan works well for this recipe.
Can I freeze the cake?
Freezing is not ideal as it can affect the delicate texture once thawed.
Why is my cake dense instead of fluffy?
This usually happens if the egg whites were not whipped properly or were overmixed into the batter.
