Separate the eggs. Make sure there is absolutely no egg yolk in with the whites.
Whip the egg whites until they form soft peaks.
Combine the egg yolks with the cream cheese and mix until smooth.
Gradually fold in the egg whites, making sure not to mix too much and take out all the air.
Divide into 10 dollops onto a greased baking tray (or you could make less, but bigger ones). I was told the size should resemble a McDonald's Big Mac bun, but it's up to you!
Bake for approx 20 mins at 160C, or until the buns have puffed up a little and turned golden brown.
Cool before eating - the texture changes from being very soft and squishy to having a bit more substance and usable as 'bread'.
