This dreamy cake combines whipped egg whites, protein powder, and Greek yogurt to create a super-light, spongy texture that feels like a soufflé met an angel food cake. It’s lightly sweet, moist, and packed with protein — great as a post-workout treat, a healthy dessert, or even breakfast!

🧁 Ingredients

Dry Ingredients:

  • ½ cup vanilla or unflavored whey protein powder (or plant protein if preferred)
    Adds the structure and protein boost.
  • ¼ cup oat flour or almond flour
    Keeps it soft and tender.
  • 1 teaspoon baking powder
    Helps it rise and stay airy.
  • Pinch of salt

Wet Ingredients:

  • 4 large eggs, separated
    (You’ll whip the whites for volume and add yolks for richness.)
  • ⅓ cup fat-free Greek yogurt
    Adds creaminess and moisture without fat.
  • 2 tablespoons milk or unsweetened almond milk
  • ¼ cup sweetener of choice (Stevia, Monk fruit, or sugar)
  • 1 teaspoon pure vanilla extract
  • Optional: ½ teaspoon lemon or almond extract for a flavor twist

For Topping (optional but lovely):

  • A light dusting of powdered sweetener
  • Fresh berries or a dollop of fat-free whipped topping
  • A drizzle of sugar-free syrup or honey

👩‍🍳 Instructions

Step 1: Prep Your Equipment

  1. Preheat your oven to 325°F (165°C).
  2. Lightly spray or grease an 8-inch round cake pan or loaf pan.
  3. Line the bottom with parchment paper to prevent sticking.

Step 2: Mix the Dry Ingredients

  1. In a medium bowl, whisk together:
    • Protein powder
    • Oat or almond flour
    • Baking powder
    • Salt
  2. Set aside — you’ll fold this in later.

Step 3: Separate and Whip the Eggs

  1. Separate the egg whites and yolks into two clean bowls.
  2. Using a hand or stand mixer, beat the egg whites on high speed until soft peaks form.
  3. Add half of your sweetener gradually while continuing to beat until you have stiff, glossy peaks — like meringue. This is what gives your cake its “cloud” texture!

Step 4: Mix the Wet Base

  1. In the bowl with egg yolks, whisk in:
    • Greek yogurt
    • Milk
    • Vanilla extract
    • Remaining sweetener
  2. Mix until smooth and creamy.

Step 5: Combine the Batter

  1. Gently fold the dry ingredients into the egg yolk mixture until combined.
    • The batter will be thick — that’s okay.
  2. Next, carefully fold in the whipped egg whites ⅓ at a time.
    • Use a spatula and gentle folding motion to keep the batter airy.
    • Don’t overmix — you want to keep all that fluff!

Step 6: Bake

  1. Pour the light, fluffy batter into your prepared pan and smooth the top.
  2. Bake for 25–30 minutes, or until the cake is lightly golden and springs back when touched.
  3. Turn off the oven and let the cake sit inside for 5 minutes with the door slightly open — this prevents collapse.
  4. Remove and let it cool completely on a wire rack.

Step 7: Serve Your Cloud Cake

Once cooled, your cake will be ultra-light and spongey!
Top with:

  • A dusting of powdered sweetener
  • Fresh strawberries, blueberries, or raspberries
  • A drizzle of sugar-free syrup
  • Or serve with a spoonful of Greek yogurt or whipped cream

Slice and enjoy your airy, high-protein creation!

💡 Tips for Perfect “Cloud” Texture

✅ Use room-temperature eggs for better volume.
✅ Don’t overmix once you add the whipped whites.
✅ Cool gradually — sudden temperature changes can deflate it.
✅ For a chocolate version, replace 1 tbsp of protein powder with cocoa powder.
✅ For extra fluff, add ¼ tsp cream of tartar to egg whites before whipping.
