If you are on a gluten free or low carb diet, you can still enjoy cloud bread! It's made with only 3 ingredients: cream cheese, eggs and baking powder. Fresh out of the oven, they are fluffy and light. Storing the cooked buns overnight in a plastic food bag adds some elasticity to them so they become more bread-like.
If cream cheese is very cold or solid, place in a microwave-safe bowl and warm in the microwave at 10-second intervals until softened, about 30 seconds. Cool to room temperature, about 5 minutes, before mixing with egg yolks.
