Costco Kirkland Signature Muffins Review

The muffins in the Costco bakery are a classic product that’s been around for years. They’re famous for their jumbo size! They come in a variety of common muffin flavors and I’m going to be reviewing each one in this post. Find out below which Costco muffin tastes the best and how many calories each kind has!

As a child, the Costco Kirkland Signature muffins from the bakery department at Costco were a major treat for my brother and me. Back then they came in a big variety pack with three or four different kinds and we would fight over who got which kind.

In this post, I’m going to be reviewing each current flavor of Costco muffin and also providing the nutrition information!

The apple crumb muffins aren’t as flavorful as I thought they would be.

Blueberry Muffins

The blueberry muffins have real blueberries!

They’re quite spongey and light. Less dense than it looks from the outside! They’re a bit crispy on the outside and soft on the inside. The blueberry muffins are moist enough but not super moist.

Each muffin is so large!

There is not a ton of flavor in the dough and they’re mildly sweet with a hint of lemon. Not a ton of blueberries and not evenly distributed but the few there are taste yummy. The blueberries add sweetness as well.

Slightly crisp exterior and soft interior.

Chocolate Muffins

The chocolate looks so good!

The chocolate muffin seems denser but not as quite dense as you would think from the outside appearance. The chocolate muffin seems a bit moister than the blueberry.

You can’t really see many chocolate chips inside.

They are very rich and chocolatey, it’s like eating a chocolate cupcake. There is the odd chunk of chocolate that gives it some texture but there aren’t a lot of those pieces. They’re quite sweet and decadent! I remember them being a lot fudgier and moist as a kid but they’re not very fudgy anymore.

Banana Chocolate Chip Muffins

The outside is golden and slightly crisp and the inside is soft.

The first thing I noticed was the nice banana smell! You can definitely tell they’re banana muffins from the smell. The muffins have a strong banana flavor too.

They look yummy!

There are a good number of chocolate chunks in the muffins, but they’re not evenly distributed. Some bites have tons of chocolate and others barely any. The chocolate chunks themselves are tasty, but nothing too special.

No chunks of banana, just chocolate chip chunks.

As with the other muffins, they’re good, but not great, particularly given how many calories you’re eating.

Chocolate Chip Muffins

Lots of chocolate on the top of this muffin.

These muffins are fairly plain – just a basic muffin mix and chocolate chips. I wondered if the muffins would have chocolate chips or chunks inside.

Top down image of the Costco chocolate chip muffins with the lid off.
Some tops are covered in chocolate chips and others have less.

After tasting them, I can confirm it seems to be the same chocolate chips that are on top mixed into the batter too. The chocolate chips aren’t super evenly distributed.

The chocolate chips are not as evenly distributed as I’d like!

Some bites have a lot more than others. Overall the chocolate chip muffins are tasty, but a little on the plain side. As a chocolate lover, I think I’d rather have a double chocolate muffin or go with the banana chocolate muffins if I’m not in the mood for pure chocolate.

I just find these ones kind of boring compared to the others.

Corn Muffins

Image of one corn muffin on a plate.
I love cornbread.

I love cornbread, so I was pretty excited to try these muffins. They are a lot like cornbread, but sweeter and with a bit less corn flavor than most cornbreads I’ve had.

Not my preferred breakfast muffin.

They also have some hard bits of corn in them. They’re not hard to the point of being crunchy, but they have a noticeable texture to them that I didn’t love.

The muffins need a bit of butter in my opinion.

The Corn Muffins were a bit on the dry side, but I did eat them on their best-before date. I didn’t put butter on them like I normally would on cornbread, but I’m sure it would make these muffins better.

Apple Crumb Muffins

The crumb topping on top is nice!

The muffin itself was a bit underwhelming. It’s not bad, but the flavors are pretty mild. I guess I’d say it’s sweet with a mild, slightly artificial apple taste? I don’t know if I’d guess these were apple muffins in a blind taste test.  The crumbs and icing on top just add sweetness.

Perfect for fall.

Overall the Apple Crumb Muffins are perfectly fine and pretty tasty, but apple fans might be disappointed.

Mild with a bit of an artificial apple taste.


You have to buy two packs of muffins at Costco, you can’t just buy one. Each pack comes with six muffins and two packs costs $9.99 Canadian and US dollars which is reasonable! Less than a dollar per muffin.

The banana chocolate muffins have a noticeable banana flavor.


The muffins have a best-before date that’s four days from the date they were packed on. The Costco muffins freeze really well so if you can’t eat 12 muffins in four days, no big deal, just pop them in your freezer.

If you’re in a single-person household or just want to buy one pack of six muffins, it is a little inconvenient that Costco forces you to buy two packs.

The Costco chocolate muffins look so rich and fudgy but they’re not as fudgy as I remember.

These are great for a snack, breakfast or dessert. Kids seem to really enjoy them as well as adults! They’re perfect to bring camping or on a road trip.

Plain chocolate chip muffins are pretty boring tasting in my opinion.


Blueberry Muffin Calories and Ingredients

The blueberry muffin has 600 calories, 33 grams of fat, 800 milligrams of sodium, 67 grams of carbohydrates, 33 grams of sugar, nine grams of protein and three grams of fiber.

I’m happy to see that there are real blueberries listed in the ingredients! The muffins contain wheat, soy, milk, egg, sulfites and may contain tree nuts, peanuts and sesame. Unfortunately, the only real healthy ingredient listed is blueberries and the oils used in the muffins as well as other ingredients are pretty unhealthy and known to be inflammatory.

  1. The Costco muffins are one of the few food items I don’t like at Costco compared to other stores.
    I find them too spongy with air pockets, and a little bland in taste.

  2. I love the blueberry, the banana & the chocolate favour. However I have to limit myself to half of a muffin each time because they used too much sugar. I don’t want to use up my daily quota so soon.
    Just think of it, the European & the Asians ain’t even as sweet as the Costco ones.
    If they could just modify them to the world standard, I could eat more & they could sell more (more business). I love the American muffins because of the texture; BUT not their sugar !

  3. I love the chocolate ones… So delicious. So good that I also got used to the yummy blueberry ones (and pumpkin!!!) too because they are so good…I’m just a chocoholic! 🙂 I’ve been wanting a site that clearly gives me their nutrition facts so thank you!

  4. Recently I made an easy thin chocolate sauce using unsweetened cocoa powder and sugar. I cut a cross into the top of the double chocolate muffin and poured the choc sauce on it and put it in the microwave for 20 seconds. Even more yummy! wonderful muffins! You could also add carmel ice cream topping for a decadent addition to the choc muffin! All Yummy!

  5. Shame on you to promote those muffins. Very very ad for your health. Sugar, bad fat, not too much fibres, transformed with additif….take the times to bake them.
    Buy good flour, fresh blueberries, apples etc….
    Less sugar, add some maple syrup.
    I find these muffins, one of the worst food to sell at Costco.
    To big too….

    • I wouldn’t say I’m “promoting them” I’m providing my own honest review of them and I don’t claim they’re healthy but I believe in a balanced diet with room for treats like this.

      • Actually, you provided the exact information I was looking for. I was looking for nutritional information on these muffins, and you gave me that, so, thank you.

      • Definitely 🙂 and what a lame commenter that was saying you’re just promoting them-clearly she wants to be ignorant. Good to know these details. Thank you! 🙂

      • Hi, like it is mentioned in the ingredients that it contains fatty acids, I just wanna confirm are they derived from animals or are they plant based? Can you please confirm if there’s any animal related ingredient used anywhere in this? Thank you!

    • Lol she is not “promoting” them. It’s a review- take from it what you will. It’s pretty obvious they are not healthy but she isn’t claiming they are. I don’t understand why you would post a comment like you did.

  6. the muffins are really big I cut them in half a eat the rest the next day they taste very good and if you freeze they still taste the same ever time I freeze them I love the blueberry and banana chocolate chip the most good price great taste what more could you ask for

  7. my favourite one is the blueberry one but I cut it in half and save the other half for the next day the taste so good and very moist keep up the good work with your muffins

  8. Your muffins are very good and very fresh. I would like to know why you discontinued the apple ones two years ago, which were the best. thank you for your reply

    • I’ve been searching, what seems like, FOREVER for the apple muffins. I had no idea that they were discontinued. I know so many ppl that loved that one. What a terrible loss.

    • This site is about Costco products. It is not Costco. The operator of this site has zero influence on the products that Costco sells or does not sell.

  9. Holy Moly! The chocolate ones have 51g of sugar??? That’s more than a 1/4 cup in each one!
    No wonder kids like them.
    Thanks but I’ll pass for sure.

  10. The best by far were the apple muffins which disappeared about 2 years ago and were replaced by the banana chocolate chip


  11. It’s a major disappointment these muffins aren’t mixed per pack. I find the Blueberry more moist compared to the chocolate. Costco needs to offer Bran muffins which are a better option than these entirely desert options. At least with the bran muffin you won’t feel as guilty like with the other sweeter varieties.

    • Yes I agree on the bran muffins why did they stop selling them? They were rated number 2 in my book along w blueberry ones. They were my go too daily. This was a big let down far as bakery section. I really hope they bring them back I’d rather see bran muffins than chocolate but that’s just me. Bc I’m not a chocolate fan! Please bring the BRAN MUFFINS BACK PLEASE 🙏
