Costco Carrot Cake: We Scanned It. Here Is What You Are Actually Eating.
One slice. 450 calories. 42g of sugar. Here is the full nutrition breakdown and what the traffic light shows.
Short Answer
One slice of Costco carrot cake (113g, 1/12 of the whole cake) has 450 calories, 42g of sugar, and 8g of saturated fat. The 42g of sugar in a single slice exceeds the American Heart Association recommended daily limit for women (25g) and nearly hits the limit for men (36g). It scores red for sugar, red for fiber, and red for saturated fat. Fine as an occasional dessert, not a regular one.
The Full Nutrition Facts: One Slice (113g)
This is the nutrition label data for the Costco Carrot Bar Cake, per one slice as listed on the product label. Note that the physical pieces cut from the full sheet are often larger than 113g, which means calories and sugar per actual serving tend to run higher than the label states.
| Nutrient | Per slice (113g) | % Daily Value | Traffic light |

| Total Fat | 22g | 28% | Yellow |
| Saturated Fat | 8g | 40% | Red |
| Trans Fat | 0g | Green | |
| Cholesterol | 55mg | 18% | Yellow |

| Added Sugars | ~38g | 76% | Red |
| Protein | 4g | 8% | Red |
Daily Values based on a 2,000 calorie diet. Added sugar DV based on AHA recommendation (25g women, 36g men).
What the Traffic Light Actually Shows
Red: Sugar (42g per slice)
This is the number that matters most. The American Heart Association recommends no more than 25g of added sugar per day for women and 36g per day for men. One slice of Costco carrot cake delivers 42g of total sugar, approximately 38g of it added. That is the entire day's limit in a single serving, with nothing left for the rest of the day's food.
The cream cheese frosting is the primary driver. It contains cream cheese, butter, and powdered sugar layered generously on top of a cake that is already sweetened. The carrot in carrot cake does not meaningfully offset this.
Red: Saturated Fat (8g, 40% of daily value)
The combination of cream cheese frosting and vegetable oil in the cake itself pushes saturated fat to 40% of the recommended daily limit in one slice. For anyone managing heart health, this is the second number to watch after sugar. The AHA recommends keeping saturated fat below 13g per day on a 2,000-calorie diet.
Red: Fiber (1g, 4% of daily value)
Despite containing shredded carrots, a single slice has only 1g of dietary fiber. The fiber from the carrots is largely offset by the refined flour and sugar structure of the cake. Low fiber combined with 60g of carbohydrates means a significant glycemic impact with minimal nutritional offset.
Yellow: Calories (450 per labeled slice)
450 calories per slice is significant for a dessert, but the bigger concern is portion reality. The labeled serving is 113g, but Costco sheet cakes are large and the pieces people actually cut tend to run 140-180g. At 180g, the actual calorie count is closer to 720 calories per serving. The label understates what most people eat.
The One Swap That Changes It Most
The frosting is doing the most damage. A traditional cream cheese frosting recipe uses cream cheese, butter, and powdered sugar in roughly equal parts by weight. Replacing half the butter with Greek yogurt and reducing the powdered sugar by one-third cuts the added sugar by approximately 15-18g per slice and the saturated fat by 3-4g, while keeping the frosting structure and tang.
The cake layer itself is harder to improve without changing the recipe significantly. The carrots and spices are the good news in the ingredient list. The enriched flour and oil are where the nutritional trade-offs live.
The one swap
Replace half the butter in the cream cheese frosting with full-fat Greek yogurt. Reduce powdered sugar by one-third. Result: approximately 120 fewer calories per slice, 15g less sugar, 3g less saturated fat. The frosting stays creamy and the carrot cake flavour profile is unchanged.
How to Scan It Yourself
The numbers above are from the product nutrition label. To see how the Costco carrot cake fits your specific daily targets, scan the barcode with the easyChef Pro food scanner. It matches the UPC against 800,000+ USDA-verified products and shows you the full breakdown against your personal daily targets, not just the generic daily values on the label.
If you are tracking sugar for blood sugar management, the traffic light will show red immediately. If you are tracking for general wellness, the calorie density is the primary flag. The tool adjusts which factors it highlights based on your health goal.

Costco's bakery section is known for large portion sizes and generous sugar. The carrot cake is not an outlier in the lineup, but the sugar content is among the highest in their bakery per labeled serving. For comparison, a typical Costco muffin runs 600-690 calories with 40-50g of sugar per piece. The carrot cake is slightly lower in calories but similar in sugar per labeled serving.
The real question is frequency. A single slice of Costco carrot cake as an occasional dessert is not a nutritional crisis. The issue is that the whole cake is sold in a 5-pound sheet that sits in the fridge for a week, and the "one slice" commitment rarely stays at one slice.
Frequently Asked Questions
- Is Costco carrot cake healthy?
- Costco carrot cake is a high-sugar, high-calorie dessert. One slice (113g) contains 450 calories, 42g of sugar, and 8g of saturated fat. The 42g of sugar in a single slice exceeds the American Heart Association recommended daily limit for women (25g) and nearly hits the limit for men (36g). It is fine as an occasional treat, but the portion size and sugar load make it one of the more significant desserts in the Costco bakery lineup.
- How many calories are in a Costco carrot cake?
- One slice of Costco carrot bar cake (approximately 113g, or 1/12 of the whole cake) contains 450 calories. The whole cake contains approximately 5,400 calories. The serving size on the label is one slice, but the physical slices cut at Costco are often larger than the stated 113g, which means actual calories per serving can be higher.
- How much sugar is in Costco carrot cake?
- One slice of Costco carrot cake contains 42g of total sugar, of which approximately 38g is added sugar. The AHA recommends no more than 25g of added sugar per day for women and 36g for men. A single slice approaches or exceeds that entire daily limit depending on your gender.
- What is in Costco carrot cake?
- Costco carrot bar cake contains enriched flour, sugar, shredded carrots, vegetable oil, eggs, and spices (cinnamon, nutmeg). The cream cheese frosting contains cream cheese, butter, powdered sugar, and vanilla. The frosting is the primary contributor to both the saturated fat and added sugar content.
- Is the Costco carrot bar cake the same as the carrot cake?
- Yes. Costco sells its carrot cake in a rectangular sheet pan format, which is why it is sometimes called the "carrot bar cake" or "carrot sheet cake." It is the same product listed under both search terms. The nutrition facts are the same regardless of which name is used.
