A single muffin (110g) now contains 460 calories, a significant reduction from its predecessor but still a substantial amount for a single baked good.

Key Ingredients and Allergens
The ingredient list for the Kirkland Signature Blueberries & Cream Muffin is extensive and includes enriched wheat flour, sugar, blueberries, and various additives and flavorings. Notably, the muffin contains common allergens such as eggs, gluten, and milk. According to a product analysis on Open Food Facts, the presence of certain additives and the overall ingredient list classify it as an ultra-processed food.
A Historical Perspective: The Older, Larger Muffin
Long-time Costco shoppers may remember the original, larger blueberry muffins. These were known for their truly massive size and even more imposing nutritional content. A single original muffin could contain over 600 calories, with one analysis from CalorieKing citing 609 calories, 32g of fat, and 40g of sugar. It is this older version that is sometimes referenced in outdated nutrition blogs and fitness tracking apps. The calorie reduction in the newer muffins, while still high, shows that even manufacturers of notoriously oversized treats are sometimes making changes.
Comparison of Kirkland Muffins
For context, here is how the Blueberries & Cream muffin compares to other options in Costco's bakery section, using the most recently available information:
| Nutrient | Kirkland Blueberry | Kirkland Corn Muffin | Kirkland Chocolate Muffin |
|---|---|---|---|
| Calories | 460 | 290 | 690 |
| Total Fat | 25g | 10g | 38g |
| Saturated Fat | 15g | 2g | 12g |

Making an Informed Choice
Given the calorie, fat, and sugar content, it is clear that the Kirkland blueberry muffin is more of an occasional indulgence than a healthy breakfast staple. For those looking to enjoy this treat responsibly, consider these strategies:
- Portion Control: Instead of eating a whole muffin, consider splitting it in half or even quarters. You can store the rest for later in an airtight container.
- Mindful Eating: Savoring a smaller portion can be just as satisfying and reduces the overall caloric impact. Pair it with a cup of coffee or tea to make the experience feel more like a special treat.
- Consider Alternatives: As shown in the comparison table, Costco offers a lower-calorie Corn Muffin. Additionally, many grocery stores sell smaller, pre-packaged muffins with more controlled portions and nutritionals. Baking your own at home also gives you complete control over the ingredients and macronutrients.
Conclusion
While delicious, the Kirkland blueberry muffin is undeniably high in calories, fats, and sugars. The most current 'Blueberries & Cream' version contains 460 calories per muffin, though older versions were even higher. By understanding the nutrition facts for this popular item, you can make a more informed decision about how to incorporate it into your diet. Ultimately, for most individuals, it is best enjoyed as a once-in-a-while treat rather than a regular part of a health-conscious eating plan.
