Whether served on its own, topped with fresh fruit, or paired with a light frosting, it’s a deliciously satisfying dessert that doesn’t weigh you down.


Servings & Timing

Yield: 8 slices
Prep Time: 10 minutes
Bake Time: 20–25 minutes
Total Time: About 35 minutes


Ingredients List

Cloud Cake Base

  • 125 grams liquid egg whites (about 4 large egg whites)
  • 34 grams angel food cake protein powder

Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan or line it with parchment paper for easy release.


Step 2: Whip the Egg Whites

In a clean, dry mixing bowl, whip the liquid egg whites until soft peaks form. This should take about 3–4 minutes using an electric mixer on medium speed.


Step 3: Mix the Protein Powder

Once the egg whites are whipped, gently fold in the angel food cake protein powder. Use a spatula to fold the powder into the egg whites, being careful not to deflate the mixture.

The batter should remain light and airy, with a smooth, mousse-like texture.


Step 4: Bake

Pour the batter into the prepared cake pan and smooth the top with a spatula. Bake for 20–25 minutes, or until the cake is golden brown and a toothpick inserted in the center comes out clean.


Step 5: Cool and Serve

Allow the cloud cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This will help maintain its airy texture.

Once cooled, slice and serve. You can top the cake with whipped cream, fresh berries, or enjoy it plain.


Additional Notes

  • Be sure to whip the egg whites until they form soft peaks, which is key for a fluffy cake.
  • You can adjust the sweetness of the cake by adding a sweetener to the batter if desired.
  • The cake may shrink slightly as it cools, which is normal.
