Why This Cloud Bread Loaf Is a Keto Favorite
Many keto bread recipes use almond flour, coconut flour, or ground seeds as their base. While delicious, they’re usually high in fat, dense in texture, and can throw off your macros if you’re not careful. This cloud bread loaf flips that model on its head. It’s fat-free, grain-free, and protein-packed, allowing you to add in the fats you choose – like avocado, bacon, or butter – without tipping your macros.
It’s not just low-carb. It’s zero-carb, meaning every slice supports your keto goals while giving you the satisfaction of real bread.

Follow these steps to make the perfect keto cloud bread breakfast sandwich:
- Preheat your convection (fan-forced) oven to 160°C (320°F).
- Using a large, clean, and dry bowl, beat the egg whites on medium speed until they form stiff peaks, this should take around 5 to 8 minutes. Use a stand or handheld electric mixer.
- Add the whey protein powder and cream of tartar, and mix on low until combined and uniform in color.
- Grease a loaf pan with butter and line it with parchment paper. (Pro tip: scrunch the parchment into a ball and unfold to mold it better to the pan.)
- Spoon the mixture into the tin, shaping it into a loaf that slightly rises above the top edge.
- Bake for 30 minutes.
- Turn off the oven, crack the door open, and place a kitchen towel in the door to keep it ajar. Let the loaf sit inside for 20–30 minutes to cool slowly, this prevents deflating.
