Ingredients

1 cup (240g) thick Greek yogurt (plain, full-fat or 2%)
3 large eggs, separated
3 tablespoons sugar or low-calorie sweetener
2 tablespoons cornstarch (or protein powder for extra protein)
½ teaspoon baking powder
1 teaspoon vanilla extract
Pinch of salt
Optional: lemon zest for freshness

Step-by-Step Instructions

1. Preheat & Prepare

Preheat oven to 325°F (160°C).
Line a small 6–7 inch (15–18cm) round pan with parchment paper. Lightly grease the sides.

2. Mix the Yolks

In a bowl, whisk together:

Greek yogurt
Egg yolks
Sugar or sweetener
Cornstarch
Baking powder
Vanilla extract

Mix until smooth and creamy.

3. Whip the Egg Whites

In a clean bowl, add egg whites and a pinch of salt.

Beat until stiff peaks form. The meringue should be glossy and hold its shape.

4. Fold Gently

Add one-third of the whipped egg whites to the yogurt mixture and gently fold to lighten it.

Then carefully fold in the remaining egg whites in two batches.

Do not overmix — keep as much air as possible for maximum fluffiness.

5. Bake

Pour the batter into the prepared pan and smooth the top.

Bake for 30–40 minutes, until the top is lightly golden and the center is set.

Turn off the oven and leave the cake inside with the door slightly open for 10 minutes to prevent collapsing.

Let cool completely before removing from the pan.

Tips for Maximum Fluffiness

Make sure the bowl for egg whites is completely clean and grease-free.
Do not overfold — gentle folding keeps the cake airy.
Bake at lower temperature to avoid cracking.
Let the cake cool gradually inside the oven.

Protein Boost Options

Replace cornstarch with 2 tablespoons vanilla protein powder.
Add 1 tablespoon collagen peptides (mix into yolk mixture).
Use strained high-protein Greek yogurt for thicker texture.

Flavor Variations

Lemon Cloud: Add 1 teaspoon lemon zest + 1 tablespoon lemon juice.
Berry Swirl: Gently swirl sugar-free berry puree into the batter.
Chocolate Cloud: Add 1 tablespoon cocoa powder.
Cinnamon Spice: Add ½ teaspoon cinnamon.

Serving Ideas

Storage

Refrigerate in an airtight container for up to 4 days.
Best served chilled or slightly at room temperature.
