Yes, this recipe can fit a high-protein lifestyle, particularly when divided into six servings.

My Personal Experience
- The whipped egg whites make a noticeable difference.
They give this particular cloud cake its signature airy structure rather than the dense texture of a conventional protein cake. - I found the vanilla flavor works especially well here.
Because the recipe contains no added sugar, vanilla helps give the cake a naturally dessert-like aroma and flavor. - The protein powder needs gentle handling.
Folding it into the egg mixture gradually helps preserve the volume created by the whipped whites. - The cake is particularly enjoyable once slightly cooled.
The center becomes soft and tender while the outside develops a delicate, lightly golden finish.

Common Mistakes to Avoid
- Under-whipping the egg whites — Soft, stable peaks are important because they provide most of the cake’s airy structure.
- Overmixing after adding the protein powder — Vigorous mixing can knock out the air and leave the cake noticeably flatter.
- Using a very high oven temperature — Excessive heat can brown the outside quickly while leaving the center undercooked.
- Removing it from the oven too quickly — Allow the cake to cool gradually so the delicate structure has time to set.
Required Equipment
- Large mixing bowl — Provides enough room to whip the egg whites without overflow.
- Electric hand mixer or stand mixer — Makes it easier to achieve stable peaks.
- Rubber spatula — Helps fold the protein mixture gently without losing too much air.
- 8-inch round cake pan — Gives the cloud cake a manageable thickness for even baking.
- Parchment paper — Helps reduce sticking and makes removal easier.
- Kitchen scale — Improves accuracy when measuring protein powder and almond flour.
Storage Instructions
Store leftover cloud cake in an airtight container in the refrigerator for up to 3 days. Place parchment between pieces if stacking them to help prevent sticking.
For longer storage, wrap individual portions tightly and freeze them in a freezer-safe container or bag for up to 1 month. Thaw overnight in the refrigerator before serving.
For the best texture, reheat one portion in a microwave for approximately 10–15 seconds, or enjoy it chilled. Avoid excessive reheating because it can make the protein-rich cake rubbery.

Short Description 📝
This high-protein keto cloud cake is fluffy, lightly sweet, and completely free from added sugar.
Egg whites, whey protein, eggs, and Greek yogurt make it a protein-friendly choice.
It is a simple low-carb treat for breakfast, snacks, or dessert.
📝 Ingredients
- 8 large egg whites — approximately 240 g, room temperature
- 2 large whole eggs — approximately 100 g
- 60 g unflavored or vanilla whey protein isolate — choose a low-carb variety
- 60 g plain full-fat Greek yogurt — unsweetened
- 20 g almond flour — finely ground
- 30 g granulated keto-friendly sweetener — adjust according to sweetness preference
- 1 tsp vanilla extract
- 1/2 tsp cream of tartar — helps stabilize the whipped egg whites
- 1/4 tsp fine salt
- 1/2 tsp baking powder
Ingredient note: If your whey protein is already sweetened, reduce the keto sweetener to taste. Use unsweetened Greek yogurt to keep unnecessary carbohydrates low.
Directions
- Preheat the oven to 325°F (165°C).
Line the bottom of an 8-inch round cake pan with parchment paper. Lightly grease only the areas where needed, as excessive grease can make the delicate batter harder to climb. - Separate the eggs carefully.
Place the 8 egg whites in a completely clean, dry bowl. Even a small amount of yolk or grease can interfere with whipping. - Whip the egg whites.
Beat on medium speed for about 1–2 minutes, then add the cream of tartar. Increase to medium-high and whip for approximately 3–5 minutes, until glossy medium-stiff peaks form. - Prepare the protein mixture.
In another bowl, whisk the 2 whole eggs, Greek yogurt, whey protein, almond flour, sweetener, vanilla, salt, and baking powder until smooth. Do not overmix. - Fold gently.
Add about one-third of the whipped egg whites to the protein mixture and fold gently. Add the remaining whites in two additions, using a rubber spatula and slow folding motions. High-protein cooking tip: gentle folding preserves air and helps prevent the protein powder from producing a dense texture. - Transfer to the pan.
Pour the batter into the prepared pan and smooth the top carefully. Do not bang the pan on the counter because this can release the air bubbles you just created. - Bake at 325°F (165°C) for 25–30 minutes.
The cake should look lightly golden, feel set around the edges, and spring back gently when touched in the center. A toothpick inserted into the middle should come out mostly clean. - Cool gradually.
Turn off the oven, open the door slightly, and leave the cake inside for about 5 minutes. Remove it and allow it to cool for another 15–20 minutes before slicing. - Serve.
Cut into 6 portions and serve plain, or add a small amount of unsweetened whipped cream, berries, cinnamon, or a dusting of powdered keto sweetener.
