How Can You Know the Expiration Date of Reese’s Peanut Butter Cups?

It’s disgusting to consume expired or spoilt peanut butter cups. For this reason, it’s advisable always to check whether your butter is still in perfect condition before buying or using it. 


But how can you know the expiration date of this candy? Every Reese’s peanut butter cup package has an expiry date. This date is written or stamped in the form of a code on the wrapper. 

This code is a number followed by a letter, for instance, 21F. The number refers to the year, while the letter refers to the month. So, 21 means 2021, and F = June, the sixth month and the alphabet’s sixth letter.

Therefore, when purchasing these Reese’s candies, ensure you check the code on the wrapper. If this code implies that the candy is past its prime, then don’t buy it. Even though you can continue enjoying this delicious candy after the expiry date, its freshness might not last for long.


Do Reese’s Peanut Butter Cups Go Bad?

Yes. These candies can spoil after the ‘use by’ date elapses. Also, storage conditions and the ingredients used can contribute significantly to their lifespan.

Although it’s most likely that this peanut butter will be rancid a few days after the ‘use by date’ elapse, most people continue to consume the product even for months. The reason is that they don’t become stale immediately after the expiration. If stored properly and unopened, these candies can remain at peak quality four to six months after the expiration date.

If you store Reese’s peanut butter cup in extremely high temperatures, the chances of remaining fresh even for five days are minimal. When exposed to humidity, they can discolor and melt, making them unfit for consumption.

Also, ingredients like sugar and oils can make these candies rancid quickly. However, this depends on their exposure to light, humidity, or high temperatures. Código P0300: Solución y Causas | Actualizado 2023
