The High-Protein Cloud Cake

No flour, no refined sugar, and packed with protein.

Ingredients

  • 4 Large Eggs (separated into whites and yolks)

  • 1 ½ cups (approx. 350g) Plain Greek Yogurt (thick, strained yogurt works best)

  • 3 tbsp Cornstarch or Arrowroot Powder (to help stabilize the structure)

  • ¼ cup Natural Sweetener (Honey, Maple Syrup, or Stevia/Monkfruit to taste)

  • 1 tsp Vanilla Extract

  • A pinch of Salt

  • Optional: 1 tsp Lemon juice (helps the egg whites peak)

Instructions

  1. Prep the Oven: Preheat your oven to 150°C (300°F). Line a 6 or 7-inch round cake pan with parchment paper. Pro tip: Make sure the parchment paper sticks up higher than the pan edges, as this cake will rise quite a bit!

  2. Mix the Base: In a medium bowl, whisk together the egg yolks, Greek yogurt, sweetener, vanilla, and cornstarch until the mixture is completely smooth and creamy.

  3. Whip the Whites: In a separate, very clean glass or metal bowl, add the egg whites and a pinch of salt (and lemon juice if using). Use a hand mixer or stand mixer to beat them on high until stiff peaks form. You should be able to turn the bowl upside down without the whites moving.

  4. The Fold (Crucial Step): Gently fold about 1/3 of the egg whites into the yogurt mixture to lighten it up. Then, add the rest of the whites. Use a spatula to gently fold in a “U” motion—do not stir or whisk, as you want to keep all that air inside.

  5. Bake: Pour the batter into your prepared pan. Bake for 45–50 minutes. The top should be golden brown, and the cake should have a slight jiggle.

  6. The Cool Down: Turn off the oven and leave the door slightly ajar for 10 minutes before taking it out. This prevents the cake from collapsing too quickly.

  7. Chill: For the best texture, let it cool to room temperature, then refrigerate for at least 2 hours. This sets the “custard” texture inside.

Nutrition Note

Because this recipe uses Greek yogurt and eggs as the primary ingredients, it is exceptionally high in protein compared to traditional sponges. It’s a great way to satisfy a sweet craving while staying fueled.
