A Detailed Look at Costco Muffin Fat Content by Flavor
When you pick up a large Kirkland Signature muffin from the Costco bakery, you're getting a treat that packs a considerable nutritional punch. Unlike standard-sized baked goods, Costco's muffins are exceptionally large, which accounts for their high calorie and fat content. As of late 2024 and into 2025, specific nutritional values have been updated, reflecting changes to some recipes. The amount of fat in a Costco muffin is not a single number, but rather a range that depends entirely on the flavor you choose.
The Fat Content of Popular Muffin Varieties
For most recent data, the fat content for popular Costco muffin flavors varies widely:
- Corn Muffin: This flavor is consistently the lowest in fat, containing approximately 10 grams of fat and 290 calories per muffin. It also has the lowest saturated fat content, making it the most diet-friendly option of the bunch.
- Lemon Raspberry Muffin: This muffin contains around 23 grams of fat and 420 calories. With 14 grams of saturated fat, it exceeds the American Heart Association's daily recommendation for saturated fat intake.
- Blueberries & Cream Muffin: Tied for the highest-calorie option, the Blueberries & Cream muffin contains 25 grams of fat and 460 calories. It is also high in saturated fat, with 15 grams per serving.
- Cinnamon Chip Muffin: Also at 460 calories, this muffin has 26 grams of fat, with 16 grams of saturated fat. Both the Cinnamon Chip and the Blueberries & Cream flavors are significantly high in fat and calories due to their large size and indulgent ingredients.
- Double Chocolate Muffin: Older data indicated a very high fat count for this flavor, sometimes cited as high as 38 grams or 39 grams. However, some nutritional tracking sites and reported store data may reflect different formulations. Recent reports based on retailer data suggest a triple chocolate version may contain around 410 calories, but specific fat numbers for the current formulation may need verification on the packaging. It is safest to assume the total fat is high for any double or triple chocolate variety.
What Influences the Fat Count?
The total fat in a Costco muffin comes from several key ingredients. The primary sources of fat include the type of oil or fat used in the batter and the added inclusions like chocolate chips or cream cheese fillings. The recipe was reportedly changed around 2024 to use butter instead of soybean oil in some flavors, which can affect the fat composition. Additionally, toppings like streusel or cinnamon chips contribute to both the overall calorie and fat count.

Making Healthier Choices with Costco Muffins
Given the high fat and calorie density of Costco muffins, especially the large-sized bakery items, it's important to be mindful of your consumption. A single muffin can account for a significant portion of your daily recommended fat and calorie intake. If you are watching your fat intake, the Corn muffin is the best option available at the bakery. For those who can't resist other flavors, consider these strategies:
- Split the muffin. A simple way to enjoy the treat without overdoing it is to cut a muffin in half or even quarters and share it. This significantly reduces your fat and calorie consumption.
- Make it an occasional treat. Save the higher-fat muffins for special occasions rather than making them a regular part of your breakfast or snack routine. This helps manage your intake over the long term.
- Choose healthier alternatives. The search results provide recipes for healthier, homemade muffins that use ingredients like Greek yogurt, whole wheat flour, and unsweetened applesauce to reduce fat and sugar. Making your own can give you control over the ingredients and nutritional content.
Conclusion
The grams of fat in a Costco muffin range from roughly 10g in the Corn muffin to over 25g in flavors like Cinnamon Chip and Blueberries & Cream, with older recipes for Double Chocolate showing even higher figures. Due to their large size, all Costco muffins are calorie and fat-dense. While they can be a delicious indulgence, they should be enjoyed in moderation and with an awareness of their nutritional impact. For a healthier alternative, consider smaller portion sizes or preparing your own low-fat muffins at home, which allows for full control over ingredients and nutrition.

What is the difference between saturated and unsaturated fats?**
Saturated fats, typically solid at room temperature, are primarily found in animal products like butter and cheese. Unsaturated fats, which are liquid at room temperature, are found in plant-based oils, nuts, and seeds.
How does the fat content of a Costco muffin compare to other muffins?**
Due to their oversized nature, Costco muffins generally have a much higher fat content than standard, smaller-sized muffins from other stores or homemade recipes. Always check portion sizes when comparing nutrition labels.
Can I reduce the fat content of a Costco muffin by removing the top?**
While removing the muffin top will reduce overall calories and fat, a significant amount of fat is baked into the batter throughout the entire muffin. It will not make it a truly low-fat item.
Why did the nutrition facts change for Costco muffins in recent years?**
In recent years, Costco reportedly updated its bakery recipes to use butter instead of soybean oil in some muffins, leading to changes in the overall nutritional profile, including fat and calories.
How much of my daily fat intake does one Costco muffin represent?**
A single, higher-fat Costco muffin (e.g., Cinnamon Chip with 26g fat) can easily account for a large percentage of your daily recommended fat intake, especially for saturated fat, based on a 2,000-calorie diet.
What are some low-fat alternatives to Costco muffins?**
Healthier, low-fat alternatives include homemade muffins made with healthier ingredients like whole wheat flour, applesauce, and yogurt, or opting for a smaller portion. The Costco Corn muffin is the lowest-fat option from the bakery.
How can I find the most accurate nutritional information for the current Costco muffins?**
For the most precise information, check the nutritional labels provided directly by Costco, which can sometimes be found on the product packaging or through official retailer sites for same-day delivery. Online nutrition databases may have outdated info.
