Is expired Bisquick deadly

Expired Bisquick is not typically deadly, but it may lose its potency and flavor over time. If stored properly, it can still be safe to use for some time after the expiration date, though its texture and rising ability might be compromised. Always check for any signs of spoilage, such as off smells or discoloration, before using. When in doubt, it's best to err on the side of caution and discard it.
