Costco Muffin - All Flavors, Calories, Pro Tips, and Hacks
Kirkland Signature Muffins (Blueberry, Chocolate, Poppyseed) at Costco
Costco sells a dozen fresh baked muffins for $8.99. The muffins are made fresh daily at each Costco location and are found in the bakery section of the warehouse.
They are found near the cinnamon rolls, bagels, and pumpkin cheesecake.
To make your pack of dozen muffins, you have the option to mix and match the flavors that Costco is offering for that day.
Three Costco Muffin Flavors
Costco’s three cornerstone flavors are chocolate, blueberry, and almond poppyseed.
Costco has offered other muffin varieties over the years, but these three flavors have stood the test of time and are now timeless Costco classics.
How Big are Costco Muffins?
When it comes to the muffins, Costco doesn’t mess around. Each muffin weighs nearly 6 ounces and has a diameter of 4 inches.
The Costco muffins live up to the Costco name and are definitely some of the most enormous store-bought muffins.

How Much Do Muffins Cost at Costco?
Costco sells 12 fresh baked muffins for $8.99. This breaks down to $0.75 per muffin. The Costco Muffins are still a bargain despite raising their price from $7.99 to $8.99 because they are large, flavorful, and come in a variety.
Costco Vs The Competition
Sam’s Club sells a 9-pack of their Member’s Mark muffins for $6.74 or $0.75 each. This is the same price as Costco’s muffin pack but without the ability to select flavors.
Sam’s Clubs’ 9 pack is preassembled with their 3 flavors of banana nut, blueberry, and double chocolate.
Kirkland Signature Muffin - Taste Test
Costco Chocolate Muffin Review
Muffin or Dessert?
The double chocolate chip muffin is many Costco members’ favorites, and for good reason. The Costco chocolate muffin is essentially a chocolate cupcake dessert.
The Costco chocolate muffin is filled with an abundance of large chocolate chips.
Double Chocolate is Double Sweet
For taste, this Costco chocolate muffin is, of course, going to be on the sweeter side.
If this was considered a dessert, I wouldn’t complain and say it wasn’t. Since it’s considered a muffin, I guess we can eat this double chocolate muffin cake for breakfast with no guilt.
Can be Dry
The one issue I have with the chocolate muffin is that it is on the dryer side. I would easily consider it the driest of the 3 Costco muffin flavors, but it is still tasty nonetheless.
Something to Know: If you warm the Costco double chocolate chip muffin, the chocolate chips will melt and become melted liquid chocolate that is embedded within the muffin.
Blueberry Muffin Review
Packed with Blueberries
My personal favorite of the Costco muffin flavors is going to be the Blueberry Muffin.
A much more traditional breakfast muffin compared to the chocolate version, this muffin is jam-packed with blueberries and flavor.
The blueberries are fair in size, and Costco definitely does not skimp out. On almost any given bite, you can expect on average 1 and a half blueberries.
Acceptably Sweet, But Can Be Too Much For Me
The Costco blueberry muffin can be sweeter than it should be at times. I’m not a sweets fan, so I would have preferred more of a buttery-tasting interior.
Almond Poppy Seed Muffin Review
The Almond Poppy Seed Muffin from Costco is very nice but my least favorite of the three primary flavors. The Costco poppy seed muffin has a somewhat moist interior.
There could be some improvement in the moisture for the Almond Poppy muffin along with the rest of Costco’s muffins.
Great Poppyseeds
Plenty of poppyseeds are spread throughout the muffin and bring a very nice sweet and nutty flavor to the Costco poppyseed muffins. They also add a lot of texture to the muffin and provide a delightful crunch.
Mantecada Muffins
I picked up a pack of Mantecada Muffins when visiting my in-laws in California. The Manteca muffin was unavailable at my local Costco, so the offerings must vary by region.
The red muffin liner is a unique touch to the Costco Mantecada muffin.
The Mantecada Costco muffin very much reminded me of a pound cake, and I would even go as far as calling it a pound cake in muffin form.
There is some sweetness to the muffin, but it is on the mild side and much less sweet compared to the other Costco muffin offerings.
Pumpkin Struesel Muffins
On my most recent trip to Costco, I did spot the famous seasonal Pumpkin Streusel Muffin. The Pumpkin Streusel is a seasonal item that runs between late summer and through the holidays.
The Costco pumpkin-flavored muffin looked terrific and had a crunchy top with a buttery cinnamon streusel.
Costco Muffins Rankings
This will vary from Costco member to Costco member, but here is how I rank the 3 muffin flavors from Costco.
- Blueberry Muffin
- Double Chocolate Chip Muffin
- Almond Poppyseed Muffin
Agree? Disagree? How do you rank the muffins?
Discontinued/Seasonal Costco Muffin Flavors
Over the past few years, Costco has started cutting back on some baked goods. In particular, they shifted their muffin focus to the 3 main flavors of blueberry, double chocolate, and almond poppy.
Some Discontinued Costco Muffin Flavors
In the past, they would offer the Big 3 Costco muffins in addition to the occasional seasonal or limited-time variety.
Here is a list of some of the discontinued or seasonal muffins:
- Vanilla Chocolate Chunk
- Coffee Cake
- Apple Crumb
- Lemon Raspberry
- Mantecada
- Pumpkin Strudel Muffin
My favorite of the discontinued muffin flavors are the Coffee Cake muffin and the Apple Crumb Muffin.
Properly Storing The Muffins from Costco
Can You Freeze Muffins from Costco?
Eating 12 Costco-sized muffins before they go bad will be a challenge for most people. Thankfully, the muffins do really well in both the refrigerator and the freezer, and the shelf life can be significantly extended.
Typically Costco’s muffins will last on the counter for about 3-4 days. For most, that isn’t going to be enough time to eat a dozen muffins.
Store in the Refrigerator
The muffins’ shelf life can be extended by simply placing the entire container in the refrigerator.
The plastic containers take up quite a bit of space, but this can nearly double the lifespan of the muffins. The muffins will stay fresh in the refrigerator for 7-10 days.
Freezing Costco Muffins
Yes, you can free Costco’s Muffins. The easiest method is to simply put the muffins into a Ziploc bag and place them in the freezer.
You can fit 4 of Costco’s giant muffins in a standard 1-gallon freezer Ziploc bag. I just place them in the Ziploc bag, but if you want an extra layer of protection, you can always wrap each muffin individually in saran wrap before placing it in the freezer bag.
The muffins can be stacked 2 by 2 in a one-gallon Ziploc freezer bag. This minimizes the amount of bags that are needed and helps efficiently use freezer space.
The bottom of one muffin may freeze to the top of another, but they can easily be separated even from the frozen state.
You can even cut the muffin in half or fourths before placing it in the freezer. Portion control is important with these giant Costco muffins.
Defrosting Muffins
Refrigerate Overnight
The muffins are super easy to defrost, and there are a few different options.
The easiest is to transfer a muffin from the freezer to the refrigerator the night before you want to eat one. The Costco muffins defrost rather quickly and will be ready to go the next morning.
Microwave
If you aren’t able to plan ahead, you can always microwave the frozen muffin until it is nice and hot. This will vary by microwave, but place the frozen microwave and heat for about 1 minute.
If your muffin needs more time, continue to heat in 20-30 second intervals until sufficiently warmed.
Costco Muffins Calories & Nutritional Information
Unfortunately, Costco’s Muffins aren’t going to be the healthiest bakery item available and are actually loaded with calories.
It may be hard to believe that what appears to be a solid breakfast choice will actually have more calories, fat, and sugar than most desserts.
How Many Calories in Costco Muffins?
Each of the Costco muffins will have approximately 650 calories with 30+ grams of fat, 70+ grams of carbs, and around 10 grams of protein. This will depend on the flavor of the muffin, but regardless, it isn’t a pretty nutritional profile.
According to Costco, one serving of their muffins is actually going to be only half a muffin. I will have the nutritional and calorie information for a half muffin serving as well as a whole muffin.

There is no way to spin it, the chocolate chip muffin is packed with calories, fat, carbs, and sugar. The muffins do come in a pack of 6, but I suggest not eating them all at once.

Final Thoughts
Costco’s Muffins are huge and awesome. They have recently increased in price, but the value is still there. A dozen muffins sell for $8.99; you must buy the full dozen.
The three cornerstone flavors of blueberry, chocolate, and poppyseed are great, and there is something for everybody. The Costco chocolate muffin is absolutely delicious!
The muffins store well in the freezer, which significantly helps their shelf life. They aren’t the best item in Costco’s bakery, but they are still worth a buy.
Asking because of allergies. Are there any other nut muffins besides almonds
