Costco Muffin Calories, Price, Pro Tips (All Flavors)
Kirkland Signature Muffins (Blueberry, Chocolate, Poppyseed) at Costco
Costco sells a dozen fresh baked muffins for $8.99. Each Costco location bakes fresh muffins daily and sells them in the bakery section near the cinnamon rolls, bagels, and pumpkin cheesecake.
You have the option to mix and match the flavors offered by Costco to make your pack of a dozen muffins. Over the past year, I’ve seen mostly blueberry, chocolate, and poppy seed flavors available. Some select warehouses have had the coffeecake flavor or the mantecada flavor.

Three Main Costco Muffin Flavors
Blueberry, Chocolate, Almond Poppyseed
The three cornerstone Costco muffin flavors are chocolate, blueberry, and almond poppyseed.Â
Costco has introduced 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?
Each Muffin Weighs 6 Ounces!
When it comes to the muffins, Costco doesn’t mess around. Each muffin weighs nearly 6 ounces and has a diameter of 4 inches.Â
The Costco muffins live up to the Costco name and are definitely some of the most enormous store-bought muffins.
Costco Cost Comparison - 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 sells the muffins in a 6 packs, but you will have to purchase 12 total muffins at $8.99. You can mix and match between 6 packs and muffin flavors.Â
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 the Costco Kirkland Signature muffin pack but without the ability to select flavors.Â
Sam’s Clubs’ pre-packs their 9 count muffins with their 3 flavors of banana nut, blueberry, and double chocolate. You do not get to select the muffins flavors you want.Â
Costco Chocolate Muffin Review
Is It Chocolate Muffin or A 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.
Costco does a great job of filling the chocolate muffin 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.Â
If Costco called the chocolate muffin a dessert, I wouldn’t complain and say it wasn’t. Since it’s categorized as a muffin, I guess we can eat this double chocolate muffin cake for breakfast guilt free.Â
Costco's Chocolate Muffin Can Be Dry At Times
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.
Microwave The Chocolate Muffin for Melty Chocolate Chips
Something to Know: Warming up the Costco double chocolate chip muffin causes the chocolate chips to melt and become liquid chocolate within the muffin.
Costco Blueberry Muffin Review
The Costco Muffins Are Packed With Blueberries
My favorite of the Costco Kirkland Signature muffin flavors is going to be the Blueberry Muffin.Â
This muffin is a traditional breakfast choice with lots of blueberries and flavor.
The blueberries are fair in size, and Costco definitely does not skimp out. On almost any bite, you can expect on average 1 and a half blueberries.
The Costco blueberry muffin is sweet
The Costco blueberry muffin can be sweeter than it should be. I’m not a sweets fan, so I would have preferred more of a buttery-tasting interior.
Costco Almond Poppy Seed Muffin Review
The Least Exciting Of The Costco Muffins
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.Â
There could be some improvement in the moisture for the Almond Poppy muffin along with the rest of the Costco muffins.
Great Tasting Poppyseeds
Costco’s poppyseed muffins contain a plethora of poppyseeds, which give them an enjoyable sweet yet nutty flavor. The poppyseeds add a lot of texture to the muffin and provide a delightful crunch.
Mantecada Muffins AT Costco
Has a Unique Red Muffin Liner
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.Â
The red muffin liner is a unique touch to the Costco Mantecada muffin.Â
The Muffin Tastes Like a Pound Cake
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 Kirkland Signature muffin offerings. Â
Costco's 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.Â
Costco Vanilla Chocolate Chunk Muffin
Update:Â As of May 2023, Costco is bringing back its Vanilla Chocolate Chunk Muffin. It appears the return of the muffin is nationwide, so keep an eye out at your local warehouse.
Many members have likened this muffin from Costco to a chocolate chip cookie and is a fan favorite. It’s already quite high in calories, but if you dare, try it with a scoop of Costco’s vanilla ice cream. Â
Costco Muffins Rankings
This will vary from Costco member to Costco member, but here is how I rank the 3 main 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 cut back on some baked goods. In particular, they shifted their muffin focus to the 3 most popular 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.Â
Â
Here is a list of some of the discontinued or seasonal muffins:
Â
- Vanilla Chocolate Chunk
- Apple Crumb
- Lemon Raspberry
- Pumpkin Strudel Muffin
Â
My favorite of the discontinued muffin flavors are the Coffee Cake muffin and the Apple Crumb Muffin.
How to Store Costco Muffins
Can You Freeze Muffins from Costco?
Eating 12 Costco-sized muffins before they go bad will be a challenge for most people. Thankfully, you can keep the muffins in both the refrigerator and the freezer, significantly extending their shelf life.Â
Typically Costco muffins will last on the counter for about 3-4 days. For most, that will not be enough time to eat a dozen muffins.
Store in the Refrigerator
Simply placing the entire container of muffins in the refrigerator can extend their shelf life.
The plastic containers take up 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 Kirkland Signature Muffins
Yes, you can free Costco Muffins. The simplest way is to put the muffins in a Ziploc bag and then freeze them..Â
You can fit 4 Costco giant muffins in a standard 1-gallon freezer Ziploc bag. You can put the muffins in a Ziploc bag or wrap each one in saran wrap for extra protection before freezing.
You can stack the muffins 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. Â
When frozen, it is easy to separate muffins even if one’s bottom has frozen to the top of another.Â
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.Â
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 Kirkland Signature Muffins are not a healthy bakery option and contain an almost outrageous amount of 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.Â
How Many Calories in Costco Muffins?
Each of the Costco Kirkland Signature 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.Â
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 and a whole muffin.Â

Final Thoughts
Costco 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.Â
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 bakery, but they are still worth a buy.
