Can you use flour that is 2 years out of date?

Flour will only stay fresh for about three months if not stored properly. If stored properly, almond flour has a shelf life of about one year. Flour's shelf life depends on what type of flour you're using and how you're storing it. In general, flour can be stored for up to eight months in an airtight container at room temperature and longer in the freezer. By moving the flour to a designated food storage container, you can extend its shelf life for up to two years, especially if you store that flour in a freezer. Expired flour has been generally shown to be okay to use, though it could impact the flavor of your finished product if it has started to go rancid. Refined Flour Wheat-based refined flours usually can be used past the expiration date, especially if it's been stored in a cool, dry place. Whole wheat flour or other grains definitely needs proper care and handling to last more than a couple of months. Oat flour can last in your freezer up to six months.
