Are Expired Cornflakes Peanut Butter Cookies OK?

I was cleaning out my pantry and found a box of cornflakes that had expired a few months ago. I hate to waste food, so I wondered if I could use the cornflakes to make peanut butter cookies. However, I wasn’t sure if it was safe to use expired cornflakes or if it would affect the quality of the cookies.

After doing some research, I learned that using expired ingredients is generally not recommended. While some foods may be safe to eat after their expiration date, it’s better to err on the side of caution and use fresh ingredients whenever possible. Expired cornflakes may not be harmful, but they can affect the texture and crunchiness of biscuits.

If you’re not sure whether an ingredient is safe or not, you can use your senses to help you decide. Look for signs of spoilage, such as mould or an off-colour, and smell the food to see if it has a sour or rancid smell. If the cornflakes look or smell off, it’s best to throw them away.

In the end, I decided to play it safe and use fresh cornflakes to make my peanut butter cookies. I hate wasting food, but I didn’t want to risk making myself or anyone else sick by using expired ingredients.
