Costco Kirkland Signature Muffins are a great price! They’re sold in packs of two for $9.99.

Ease of Use/Store

These muffins do not require any baking or additions. Simply open the container, grab a muffin, and dig in!

Storing is just as simple. Because the muffins come in a resealable package, you can simply close and seal the container and leave them right on your countertop.

You can extend the shelf life to two months if you store the muffins in the freezer. However, you’ll need to remove them from the container and seal each separately in plastic wrap and/or aluminum foil.

The Pumpkin Streusel Muffins are incredible – I rate them 5/5. The pumpkin flavor is prominent, and the maple drizzle and brown sugar topping take the muffin to the next level. It’s moist with a subtle crunchiness that is truly the embodiment of fall flavors.

So delicious – and big!

The Double Chocolate, on the other hand, was a little bit dry for me. I liked the overall flavor and the inclusion of chocolate chunks. I think this would be a spectacular option for a chocolate fanatic. Personally, I just like a little bit more variety in my bites.

Both muffins got top rankings from my kiddos, though! Makenzie said, “Yummy!” after a big bite of the chocolate muffin, while my son Pierce was blown away by the pumpkin flavor. He exclaimed, “This is amazing. I love it!”
