It is always best to eat donuts when fresh from the oven, for starters. That is why when making your homemade donuts wait until it has cooled down after you bake them. Likewise, it would be best to eat freshly made donuts you bought from Krispy Kreme or Dunkin Donuts.
Also, keep in mind that sugar, fats, and butter provide the donut with an excellent flavor. Unfortunately, these moist ingredients can be prone to bacteria. Especially if you let your donuts sit there uncovered for one to two days.
In this regard, here are easy steps to keep your store-bought or homemade donuts fresh for several days. Besides, you do not want any bit of it to go to waste.
You can always store your donuts in the freezer as a great alternative. Because of this, make sure to wrap it in an airtight freezer or container bag. Also, remember to maintain the freezer at zero degrees Fahrenheit. In addition to that, you should anticipate the texture and flavor to fade after three days.
