It's a seasonal item. It will come back
You can't "protest" Costco's actions any more than your family can "protest" your home menu. Go to the bakery and tell them that you really miss the apple cinnamon muffins. Mention to a friendly employee that apple cinnamon is your favorite and ask them if they might be bringing them back. They might be having trouble with THEIR supplier. Apple cinnamon muffins are my favorite as well so I'll be asking the same question. We can't always buy muffins so I didn't know about the situation. I'm pretty sure you have already made Costco aware as well. At least I hope they see your comments. Good luck!

The store has an area to put suggestions complaints or compliments you can request the item again. Not sure it will actually happen but find it and put it in there. Maybe you can get it back.
He's right, you have to protest 👍🏼👍🏼
I never noticed. They delist stuff all the time.
