2. Ingredients
You only need two ingredients:
3 large eggs, separated into yolks and whites.
120 g (4.2 oz) white chocolate, chopped into small pieces.
Optional for serving:
Powdered sugar
Fresh strawberries
Fresh blueberries
Whipped cream
These optional toppings are not part of the two-ingredient cake itself.
3. Step-by-Step Instructions
Step 1: Prepare the Oven and Cake Pan
Preheat your oven to 325°F (160°C).
Line the bottom of a 6-inch round cake pan with parchment paper.
Lightly grease the sides of the pan.
Separate the eggs carefully.
Place the egg whites in a clean, dry mixing bowl.
Place the egg yolks in a separate bowl.
Make sure no egg yolk gets into the egg whites because even a little fat can prevent them from whipping properly.
Step 2: Melt the White Chocolate
Break the white chocolate into small pieces.
Place it in a heatproof bowl.
Melt it using a microwave in 15–20-second intervals, stirring between each interval.
Alternatively, melt it over a saucepan of gently simmering water.
Stir until completely smooth.
Allow the chocolate to cool slightly so it is warm but not hot.
Avoid overheating the chocolate because white chocolate can become thick or grainy.
Step 3: Add the Egg Yolks
Add the egg yolks to the melted white chocolate.
Whisk gently until smooth.
Continue mixing until the mixture becomes thick and creamy.
Set aside.
If the mixture becomes too thick, make sure the chocolate was not overheated or allowed to cool too much before mixing.
Step 4: Whip the Egg Whites
Using an electric mixer, begin beating the egg whites on medium speed.
Continue until they become foamy.
Increase the speed to medium-high.
Beat until stiff peaks form.
When you lift the beaters, the egg whites should hold their shape.
This step is essential because the whipped egg whites create the cake’s light, cloud-like texture.
Step 5: Fold the Egg Whites Into the Chocolate
Add approximately one-third of the whipped egg whites to the chocolate mixture.
Gently stir to loosen the thick chocolate mixture.
Add the remaining egg whites in two batches.
Use a spatula to fold gently from the bottom upward.
Continue until no large white streaks remain.
Do not overmix. Keeping as much air in the batter as possible helps the cake rise.
Step 6: Transfer the Batter
Pour the mixture into the prepared cake pan.
Gently smooth the top with a spatula.
Tap the pan very lightly once to release large air pockets.
Place the cake pan inside a larger baking dish.
Step 7: Prepare a Water Bath
Carefully pour hot water into the larger baking dish.
The water should come approximately halfway up the outside of the cake pan.
Make sure water cannot enter the cake pan.
Place the baking dish carefully into the preheated oven.
The water bath helps the cake bake gently and reduces the risk of excessive cracking.
Step 8: Bake the Cloud Cake
Bake at 325°F (160°C) for approximately 30–35 minutes.
Watch the top as it becomes lightly golden.
The center should look set but remain soft.
Check that the cake is cooked through using a suitable food thermometer; egg-based cakes should reach 160°F (71°C) internally.
Baking time may vary depending on your oven and cake pan.
Step 9: Cool the Cake
Turn off the oven.
Leave the oven door slightly open for approximately 10 minutes.
Carefully remove the cake from the water bath.
Allow it to cool in the pan.
Once cooled, gently remove it from the pan.
Refrigerate for approximately 30–60 minutes if you prefer a firmer texture.
Step 10: Serve and Enjoy
Transfer the cake to a serving plate.
Cut into gentle slices using a sharp knife.
Add fresh strawberries or blueberries if desired.
Dust lightly with powdered sugar for presentation.
Serve chilled or slightly cool.
4. Taste and Texture

5. Ingredient Substitutions
| Original Ingredient | Possible Substitute |
|---|---|
| White chocolate | Milk chocolate, but texture and sweetness change |
| Large eggs | Medium eggs, adjusted by weight |
Important: This exact two-ingredient version depends on the structure of whipped egg whites and the fat and sugar in white chocolate. Other substitutions may require a different recipe.
6. Delicious Recipe Variations
These additions will make the cake a variation rather than the original two-ingredient version.

8. Storage and Meal Prep
Refrigerator:
Allow the cake to cool completely.
Place it in an airtight container.
Refrigerate for up to 3 days.
Keep it chilled until serving.
Freezer:
Freezing is not recommended for the best texture because the delicate, airy structure may become wet or change after thawing.
Serving Tip:
For clean slices, refrigerate the cake before cutting. Use a sharp knife and wipe it between slices.

10. Frequently Asked Questions
Q1. Can I make cloud cake with only two ingredients?
Yes. This version uses eggs and white chocolate. No flour, baking powder, or added sugar is required.
Q2. Why did my cloud cake collapse?
A little sinking is normal as the cake cools. However, excessive collapsing can happen when the egg whites are under-whipped, overmixed, or the cake is underbaked.
Q3. Can I use dark chocolate instead of white chocolate?
Yes, but dark chocolate has a different fat and sugar composition. The texture and sweetness may change, so the result may not be identical.
Q4. Do I need an electric mixer?
An electric mixer is strongly recommended because stiff egg-white peaks are important for creating the airy texture.
Q5. Can I make this cake without flour?
Yes. This recipe contains no flour.
Q6. Is this cake sugar-free?
No. White chocolate normally contains sugar, so this recipe is not sugar-free.
Q7. Why is my cake dense?
The most common reason is losing too much air while folding the whipped egg whites into the chocolate mixture.
Q8. Can I make this cake ahead of time?
Yes. Prepare it a day ahead and refrigerate in an airtight container. It may become slightly firmer after chilling.
11. Troubleshooting Guide
| Problem | Possible Reason | Solution |
|---|---|---|
| Cake collapsed | Underbaking or weak egg whites | Whip to stiff peaks and bake until set |
| Cake is dense | Overmixing | Fold egg whites gently |
| Chocolate became grainy | Overheating | Melt slowly and stir frequently |
| Cake is too sweet | White chocolate contains considerable sugar | Serve with fresh berries |
