How long do Betty Crocker baking mixes last?

Betty Crocker baking mixes have varying shelf lives depending on the specific product. Most dry baking mixes, such as cake mixes, brownie mixes, or cookie mixes, can typically be stored in a cool, dry place for up to 18 months beyond the "best by" date printed on the package. It's important to note that the quality and taste might slightly diminish after this period, but they should still be safe to consume. However, it's advisable to discard any mix that shows signs of spoilage, like a strange odor, off-color, or clumping. For the best baking results, it's recommended to use the mixes before the expiration date and store them properly to ensure freshness.
