Can you leave a cake batter with eggs out for an hour?

Raw eggs are a potential source of bacteria, including Salmonella, which can cause food poisoning. When eggs are left out at room temperature, the bacteria can multiply rapidly, making the batter unsafe to eat.

In addition, the flour in cake batter can also harbor bacteria, such as E. coli, which can cause illness. When the batter is left out at room temperature, the bacteria can multiply and contaminate the other ingredients in the batter.

For these reasons, it is important to refrigerate cake batter within two hours of mixing it. If you cannot refrigerate the batter, you can store it in a cool, dry place for up to one hour. However, it is best to refrigerate the batter as soon as possible to prevent the growth of harmful bacteria.
