Equipments
- 8-inch round springform pan for even baking and easy removal

How to Make High-Protein Cloud Cake
Step 1: Prepare the Oven and Pan
- Preheat your oven to 340°F (170°C).
- Line the bottom and sides of an 8-inch round cake pan with parchment paper to prevent sticking and make removing the cake easier after baking.
- Prepare a larger roasting pan or deep baking tray for the water bath.
Step 2: Separate the Eggs
- Carefully separate the egg whites and egg yolks into two clean, dry mixing bowls.
- Make sure no egg yolk gets into the whites, as even a small amount of fat can prevent the egg whites from whipping properly.
Step 3: Make the Yogurt Base
- In the bowl containing the egg yolks, add the Greek yogurt.
- Pour in the sugar-free condensed milk.
- Add the fresh lemon juice, lemon zest, and vanilla extract if using.
- Whisk everything together until the mixture is completely smooth, creamy, and free of lumps.
Step 4: Whip the Egg Whites
- Using an electric hand mixer or stand mixer, beat the egg whites on medium-high speed.
- Continue mixing until stiff, glossy peaks form. When you lift the beaters, the peaks should stand upright without folding over.
- If using, add the pinch of salt before whipping to help stabilize the foam.
Step 5: Fold the Batter
- Add about one-third of the whipped egg whites to the yogurt mixture and gently fold them in using a silicone spatula.
- Once combined, add the remaining egg whites in two more additions.
- Fold carefully with slow, sweeping motions from the bottom of the bowl upward, rotating the bowl as you work.
- Continue folding only until the batter is light, airy, and evenly mixed with no visible streaks of egg white. Avoid overmixing, as this will deflate the batter.
Step 6: Fill the Cake Pan
- Pour the finished batter into the prepared cake pan.
- Use a spatula to gently spread the batter into an even layer.
- Lightly tap the pan on the countertop two or three times to release any large air bubbles while preserving the cake’s airy texture.
Step 7: Prepare the Water Bath
- Place the cake pan inside the larger roasting pan or baking tray.
- Carefully pour warm water into the outer pan until it reaches about halfway up the sides of the cake pan.
- The water bath creates gentle, even heat, helping the cake bake evenly while maintaining its delicate, cloud-like texture.
Step 8: Bake the Cake
- Carefully transfer the water bath to the preheated oven.
- Bake for 40 to 45 minutes, or until the top is lightly golden and the center is just set.
- The cake should have a slight jiggle in the middle but should not appear wet.
Step 9: Cool Slowly
- Turn off the oven once the cake is finished baking.
- Leave the cake inside the oven with the door slightly open for 15 to 20 minutes.
- Allowing the cake to cool gradually helps prevent it from collapsing due to sudden temperature changes.
Step 10: Chill and Serve
- Remove the cake from the water bath and place it on a wire rack to cool completely.
- For the best texture and flavor, refrigerate the cake for 2 to 4 hours before slicing.
- Carefully remove the parchment paper, slice with a sharp knife, and serve chilled.
- Garnish with fresh berries, a dollop of Greek yogurt, a light dusting of powdered monk fruit sweetener, or a little extra lemon zest if desired.
