I make these muffins with the following ingredient:

  • Oat flour
  • Banana
  • Pea milk
  • Walnuts
  • Chia seeds
  • Sesame seeds
  • Cinamon
  • Salt
  • Baking powder

I am going to travel and want to bring some with me. I was wondering how long they would be good for without refrigeration.

  • Expiration dates strongly depend on the product itself. What can be stored without a refrigerator will retain its properties for a long time. But it matters whether you go to the Sahara or travel to the South Pole. Commented Jul 11, 2022 at 7:50
  • Travel how long ? what conditions ?

This is not a firmly answerable question, because shelf life of foods of any kind depends on many factors. Among them is the fact that the muffins can still be non-toxic, but taste terrible by becoming rancid, something that's a real danger with any baked good that includes nut flour.

For a comparison, though, most commercial vegan muffins say that they should only be kept for around 5 days.

You might get more useful information by asking "what can I do to increase the shelf life of these muffins" instead.
