Cloud bread—light, fluffy, and almost too good to be true. This viral low-carb, gluten-free alternative to traditional bread has taken kitchens by storm. Discover why it’s more than just a trend.
What Is Cloud Bread?
Cloud bread, also known as “unicorn bread” or “egg white bread,” is a soft, airy baked good made primarily from egg whites, cream of tartar, and sugar or a sugar substitute. Despite its name, it doesn’t resemble conventional bread in texture or flavor, but rather looks like a cloud—hence the name. It’s become a staple in low-carb, keto, and gluten-free diets due to its minimal carbohydrate content and simple ingredient list.
Origins of Cloud Bread
The concept of cloud bread is rooted in meringue-based recipes that have existed for centuries. However, the modern version gained popularity around 2017 during the peak of the ketogenic diet trend. Fitness influencers and clean-eating bloggers began sharing quick, easy recipes for cloud bread as a guilt-free sandwich substitute. Its viral moment came when a Food Network segment highlighted its versatility and whimsical appearance.

Basic Ingredients and Variations
The foundation of cloud bread is simple: egg whites, a stabilizer (like cream of tartar), and a sweetener. Some versions include cream cheese or heavy cream for added richness and structure. Variations now include savory cloud bread with herbs and cheese, chocolate-flavored versions with cocoa powder, and even vegan adaptations using aquafaba (the liquid from canned chickpeas) instead of egg whites.
“Cloud bread isn’t real bread, but it’s the closest thing you can get to a fluffy, melt-in-your-mouth alternative without grains.” — Nutritionist Dr. Lena Torres, speaking on Healthline
Why Cloud Bread Went Viral
The rise of cloud bread wasn’t accidental. It coincided with a cultural shift toward low-carb lifestyles, clean eating, and visually appealing food content. Platforms like Pinterest and YouTube were flooded with 30-second videos showing the dramatic transformation of egg whites into pillowy clouds in the oven. The visual appeal, combined with its health halo, made it irresistible to share.
Social Media Influence
Cloud bread’s aesthetic perfection made it ideal for Instagram and TikTok. Videos showing the puffy rise in the oven, the gentle squish when pressed, and the way it holds a slice of avocado without collapsing went viral. Influencers tagged it as #cloudbread, #ketobread, and #lowcarbsnack, creating a digital echo chamber that propelled it into mainstream awareness.
- Over 2 million posts on Instagram under #cloudbread
- TikTok videos with the hashtag have accumulated over 500 million views
- YouTube tutorials average 500K+ views per top-ranking video
Diet Culture and Health Trends
As the ketogenic and paleo diets gained traction, so did demand for bread substitutes. Traditional bread, high in refined carbs and gluten, was increasingly viewed as unhealthy. Cloud bread, with its near-zero net carbs and high protein content, fit perfectly into these dietary frameworks. It was praised as a “hack” for enjoying sandwiches without breaking ketosis.
According to a 2020 report by Statista, searches for “keto bread alternatives” increased by 300% between 2016 and 2019, with cloud bread being the most searched option.
Nutritional Profile of Cloud Bread
Understanding the nutritional value of cloud bread is essential for anyone considering it as a dietary staple. While it’s low in carbs and calories, it’s not a complete replacement for whole-grain bread in terms of fiber and micronutrients.
Macronutrient Breakdown
A typical serving of cloud bread (one “bun” or two small pieces) contains approximately:
- Calories: 50–70
- Protein: 3–5 grams (from egg whites)
- Fat: 1–3 grams (depending on added cream or cheese)
- Carbohydrates: 1–3 grams (mostly from sweetener)
- Fiber: 0 grams (unless additives are used)
This makes it ideal for those tracking macros, especially on a ketogenic diet where daily carb intake is limited to 20–50 grams.
Vitamins and Minerals
While cloud bread isn’t a significant source of vitamins, it does provide some nutrients from egg whites, including selenium, riboflavin (B2), and small amounts of potassium and magnesium. When cream cheese or herbs are added, the micronutrient profile improves slightly, offering calcium and vitamin A.
“Cloud bread can be part of a balanced low-carb diet, but it shouldn’t replace whole foods like vegetables or legumes as a primary nutrient source.” — Registered Dietitian Maria Chen, Academy of Nutrition and Dietetics
How to Make Cloud Bread: Step-by-Step
Making cloud bread is surprisingly simple, requiring only a few ingredients and basic kitchen tools. The key is patience and proper technique, especially when whipping the egg whites.
Classic Sweet Cloud Bread Recipe
Here’s a basic recipe for two servings:
- 3 large egg whites
- 1/4 teaspoon cream of tartar (or lemon juice)
- 2 tablespoons granulated sweetener (or erythritol for keto)
- Optional: 1/4 teaspoon vanilla extract
Steps:
- Preheat oven to 300°F (150°C) and line a baking sheet with parchment paper.
- In a clean bowl, beat egg whites and cream of tartar until soft peaks form.
- Gradually add sweetener and continue beating until stiff, glossy peaks form.
- Gently fold in vanilla if using.
- Spoon mounds onto the baking sheet and shape into rounds.
- Bake for 25–30 minutes until golden and dry to the touch.
- Cool completely before serving.
This version is perfect for dessert pairings, like berries and whipped cream.
Savory Cloud Bread Variations
For a savory twist, try adding:
- 2 tablespoons grated Parmesan or cheddar cheese
- 1/2 teaspoon garlic powder or dried herbs (oregano, thyme)
- Pinch of smoked paprika or black pepper
You can also mix in cream cheese before baking for a denser, more bread-like texture. This version works well as a sandwich base for turkey, avocado, or smoked salmon.
Cloud Bread in Special Diets
One of the reasons cloud bread has gained such widespread appeal is its adaptability to various dietary needs. Whether you’re keto, gluten-free, or managing diabetes, cloud bread can be customized to fit your lifestyle.
Keto and Low-Carb Diets
Cloud bread is a dream for keto followers. With less than 3 grams of net carbs per serving, it allows dieters to enjoy a bread-like experience without spiking blood sugar. Many keto bloggers use cloud bread as a base for mini pizzas, sliders, or even French toast by dipping it in egg and cinnamon before pan-frying.
A study published in Frontiers in Nutrition found that low-carb diets can improve insulin sensitivity and aid weight loss, making cloud bread a strategic tool for metabolic health.
Gluten-Free and Allergen-Friendly Options
Since cloud bread contains no grains or gluten, it’s naturally safe for people with celiac disease or gluten sensitivity. However, those with egg allergies must avoid it unless a substitute like aquafaba is used. Vegan versions using chickpea brine whipped with sugar have shown promising results, though the texture is less stable.
“For gluten-free eaters, cloud bread offers a rare sense of normalcy—being able to eat a ‘sandwich’ without feeling deprived.” — Blogger and Celiac advocate, Sarah Kim, Gluten-Free on a Shoestring
Cloud Bread vs. Traditional Bread: A Comparison
While cloud bread is often marketed as a bread substitute, it’s important to understand how it stacks up against traditional bread in terms of nutrition, texture, and functionality.
Nutritional Differences
Traditional white bread typically contains around 80 calories, 15 grams of carbs, 2–3 grams of protein, and 1–2 grams of fiber per slice. In contrast, cloud bread has fewer calories and carbs but lacks fiber and complex carbohydrates. Whole grain bread offers B vitamins, iron, and prebiotic fiber—nutrients absent in cloud bread.
- Cloud bread: High in protein, low in carbs, no fiber
- Whole wheat bread: Balanced macros, rich in fiber and micronutrients
- Cloud bread is not a nutritionally equivalent replacement but a functional alternative
Texture and Culinary Use
Cloud bread is delicate and airy, making it unsuitable for hearty sandwiches or toasting like regular bread. It can collapse under heavy fillings like pulled pork or saucy meats. However, it shines in lighter applications: topped with avocado, used as a base for eggs Benedict, or served with soft cheeses.
Its meringue-like texture means it absorbs moisture quickly, so it’s best consumed fresh. Some bakers recommend storing it in an airtight container for up to 2 days, though it loses fluffiness over time.
Common Mistakes When Making Cloud Bread
Despite its simplicity, cloud bread can go wrong if basic principles of meringue-making are ignored. Understanding these pitfalls can save you from flat, sticky, or burnt results.
Using Dirty or Greasy Bowls
Fat is the enemy of stiff egg whites. Even a trace of yolk or oil residue can prevent proper whipping. Always use a clean, dry glass or metal bowl—plastic can retain grease even after washing.
- Wipe the bowl with a lemon wedge or vinegar to ensure no oil remains
- Separate eggs carefully, avoiding yolk contamination
Under-Whipping or Over-Baking
If egg whites aren’t whipped to stiff peaks, the cloud bread won’t hold its shape and will spread or deflate. Conversely, over-baking can make it too dry or brittle. The ideal texture is soft and slightly springy, not crunchy.
Tip: Turn off the oven and let the bread dry inside with the door slightly ajar for 10 minutes after baking to prevent cracking.
“Perfect cloud bread is all about patience. Rush the process, and you’ll end up with sweet scrambled eggs.” — Chef Marco Ruiz, Bon Appétit
Cloud Bread Around the World
While cloud bread is a modern internet phenomenon, similar airy baked goods exist in global cuisines. These traditional recipes share techniques and textures, showing that the desire for light, fluffy bread is universal.
Indonesian Spiku (Sponge Cake)
In Indonesia, spiku is a layered sponge cake made with whipped egg yolks and whites, butter, and flour. While not low-carb, its airy texture is achieved through similar whipping techniques. Some keto bakers have adapted spiku recipes using almond flour and cloud bread methods.
Italian Meringhe and Baked Alaskas
Italian meringues and the outer layer of Baked Alaska use the same science of whipped egg whites and sugar. Cloud bread is essentially a simplified, less sweet version of these desserts, repurposed as a savory or neutral base.
- Technique: Italian meringue uses hot sugar syrup for stability
- Cloud bread uses cream of tartar for easier home preparation
Japanese Soufflé Pancakes
Japan’s famous soufflé pancakes are another cousin to cloud bread. Made with whipped egg whites folded into a custard base, they rise dramatically and collapse slightly when touched. The texture is nearly identical to cloud bread, and some cafes now offer savory versions with cheese and herbs.

Storing and Reheating Cloud Bread
Due to its delicate structure, cloud bread doesn’t keep as well as traditional bread. However, with proper storage, you can extend its shelf life and maintain texture.
Short-Term Storage
Store cooled cloud bread in an airtight container at room temperature for up to 24 hours. For longer freshness, refrigerate for up to 2 days. Note that refrigeration can make it slightly damp, so re-crisping in a toaster oven or air fryer is recommended.
- Use parchment between layers to prevent sticking
- Avoid humid environments to prevent sogginess
Freezing and Reheating
Cloud bread can be frozen for up to 1 month. Place cooled pieces on a tray, freeze until solid, then transfer to a freezer bag. To reheat, bake at 300°F for 5–8 minutes or use an air fryer at 320°F for 3–4 minutes until warm and slightly crisp.
Do not microwave, as it will become rubbery.
Is cloud bread healthy?
Cloud bread is low in carbs and calories, making it suitable for keto and low-carb diets. However, it lacks fiber and essential nutrients found in whole grains. It’s best enjoyed in moderation as a treat or substitute, not a dietary staple.
Can I make cloud bread without sugar?
Yes, you can use zero-calorie sweeteners like erythritol, stevia, or monk fruit. For savory versions, omit sugar entirely and add cheese or herbs for flavor. The structure remains stable as long as egg whites are properly whipped.
Why did my cloud bread collapse?
Collapse usually occurs due to under-whipped egg whites, opening the oven too early, or insufficient baking time. Ensure stiff peaks, avoid sudden temperature changes, and bake until completely dry inside.
Is cloud bread gluten-free?
Yes, cloud bread is naturally gluten-free since it contains no grains. However, always check labels on additives like cream of tartar or flavorings to ensure cross-contamination hasn’t occurred.
Can vegans eat cloud bread?
Traditional cloud bread uses egg whites, so it’s not vegan. However, aquafaba (chickpea brine) can be whipped like egg whites and used as a substitute. Vegan cloud bread is possible but may be less stable and require xanthan gum for structure.
Cloud bread is more than just a fleeting food trend—it’s a creative solution for those navigating dietary restrictions without sacrificing texture or satisfaction. While it doesn’t replace the nutritional value of whole-grain bread, its versatility, simplicity, and visual appeal make it a valuable addition to modern kitchens. Whether you’re on keto, gluten-free, or just curious, cloud bread offers a delightful, cloud-like experience that’s worth trying. With the right technique and expectations, it can be a fun, functional, and flavorful part of your culinary repertoire.
