Calories in Starbucks Butter Croissant
I used to grab a Starbucks Butter Croissant almost every morning without a second thought. It felt light, flaky, and harmless next to my grande latte. Then I started tracking my food on MyFitnessPal, and the numbers stopped me cold.
That single croissant was eating up nearly 15% of my daily calorie budget — before 9 a.m.
I’m not here to tell you to never eat it. It’s genuinely delicious. But if you’re counting calories, managing your weight, or just trying to make smarter choices at Starbucks, you deserve the full picture. Not just the headline number — the whole story behind it.
How Many Calories in a Starbucks Butter Croissant?
A Starbucks Butter Croissant contains 310 calories per croissant (85g serving). It has 18g of fat, 32g of carbohydrates, 5g of protein, and 4g of sugar. Saturated fat is 11g — about 55% of the daily recommended limit.
This is the official US Starbucks figure for a full-size croissant. Some tracking apps show 250–260 calories because they use a smaller 62g serving size. The full croissant you receive in-store weighs approximately 85g.
Why the Calorie Count Looks Different Everywhere
Here’s the thing that confused me for weeks: I’d look up “Starbucks butter croissant calories” and get three different numbers — 250, 260, and 310 — all on the same Google results page.
This is not a data error. It’s a serving size problem.
Different nutrition databases log the product at different weights:
| Source | Serving Size | Calories |
| Starbucks US Official | 85g (1 full croissant) | 310 |
| CalorieKing | 62g (2.2 oz) | 260 |
| FatSecret | 62g | 250 |
| Nutracheck (UK) | 1 serving (UK variant) | 260 |
The croissant you actually pick up at a US Starbucks location weighs around 85g. That’s the 310-calorie version. The 62g figures appear to be based on a smaller or older product variant.
Practical tip: When logging in apps like MyFitnessPal or Nutritionix, manually enter 85g or select the “Starbucks” brand entry — not a generic “butter croissant” entry — for the most accurate count.
Full Starbucks Butter Croissant Nutrition Facts
Here’s the complete nutrition breakdown for one full croissant (85g), based on Starbucks US menu data:
| Nutrient | Amount | % Daily Value |
| Calories | 310 | — |
| Total Fat | 18g | 23% |
| Saturated Fat | 11g | 55% |
| Trans Fat | 1g | — |

Calorie Breakdown by Macronutrient
- Fat: 52% of calories
- Carbohydrates: 41% of calories
- Protein: 6% of calories
This is a fat-dominant food. More than half the calories come from fat, primarily saturated fat from butter. That’s what makes it taste so rich and layered — but it’s also what makes it worth paying attention to if you’re watching your saturated fat intake.
What’s Actually Inside the Starbucks Butter Croissant?
This is the part most sites skip. Here’s the actual ingredient list:
Enriched Wheat Flour (wheat flour, niacin, reduced iron, ascorbic acid, thiamine mononitrate, riboflavin, folic acid, enzyme), Butter (cream, milk, natural flavor), Water, Sugar, Eggs, Whole Milk Powder, Yeast, Sea Salt, Sourdough (water, fermented wheat flour), Dough Conditioner (wheat gluten, ascorbic acid, xanthan gum, salt, enzymes).
A few things worth noting here:
- No artificial flavors. The ingredient list is relatively clean for a commercial baked good.
- Real butter is the second ingredient — that’s where the richness and the 11g of saturated fat come from.
- Sourdough is included in the base dough. This is a nod to the La Boulange influence — Starbucks acquired La Boulange Bakery in 2012, and their recipes brought more artisan-style techniques to Starbucks baked goods.
- Dough conditioners are present. These are common in commercial baking to improve texture and shelf stability.

How Many Calories Is That, Really? (The Activity Comparison)
Numbers on a nutrition label can feel abstract. Here’s what burning 310 calories looks like in practice:
| Activity | Time to Burn 310 Calories |
| Walking (moderate pace) | ~75–80 minutes |
| Jogging (5 mph) | ~30 minutes |
| Cycling (moderate) | ~45 minutes |
| Swimming (moderate) | ~28 minutes |
| Yoga | ~60 minutes |
Based on a 150 lb (68 kg) adult.
That’s about a 45-minute bike ride for one croissant. That’s not a reason to never eat it. But it’s a helpful reality check when you’re deciding whether to grab one every day versus occasionally.
Is the Starbucks Butter Croissant Healthy?
Short answer: It depends on your goals.
Let’s break it down honestly:
If you’re managing weight:
310 calories is not outrageous for breakfast on its own. The problem is pairing. Add a grande Caffe Latte (190 calories) or a vanilla latte (250 calories), and your Starbucks run is already at 500–560 calories — before you’ve done anything else.
The croissant is also low in protein (5g) and fiber (1g). Those two nutrients are what keep you feeling full. A 310-calorie breakfast that leaves you hungry by 10 a.m. is a tough deal.
If you’re watching saturated fat:
11g of saturated fat is significant. The American Heart Association recommends no more than 13g of saturated fat per day for a 2,000-calorie diet. One croissant gets you to 85% of that limit before lunch.
If you’re eating low-carb or keto:
32g of carbohydrates make this incompatible with strict ketogenic diets. Net carbs are 31g. This is a hard no for keto.
If you’re vegetarian:
Yes, the Starbucks Butter Croissant is vegetarian. It contains no meat or fish.
Is it gluten-free?
No. It contains wheat flour and is made in environments with gluten. It is not suitable for anyone with celiac disease or gluten intolerance.
Starbucks Butter Croissant vs. Other Starbucks Bakery Items
Wondering how the butter croissant compares to other things on the Starbucks food menu? Here’s a quick side-by-side:
| Item | Calories | Fat | Carbs | Protein |
| Butter Croissant | 310 | 18g | 32g | 5g |
| Chocolate Croissant | 340 | 19g | 42g | 7g |
| Almond Croissant | 420 | 25g | 43g | 9g |
| Blueberry Muffin | 350 | 15g | 52g | 5g |
| Banana Walnut Bread | 490 | 25g | 63g | 7g |
| Petite Vanilla Bean Scone | 120 | 5g | 17g | 2g |
| Cheese Danish | 290 | 16g | 32g | 6g |
A few observations from this table:
- The Butter Croissant is not the worst option on the Starbucks bakery menu. The Banana Walnut Bread nearly doubles the calorie count.
- The Petite Vanilla Bean Scone (120 calories) is the lowest-calorie bakery option if you want something sweet.
- The Cheese Danish is surprisingly close in calories (290) with a bit more protein (6g).
- The Almond Croissant looks similar but packs 420 calories — 35% more than the butter version.
How to Work It Into Your Diet Without Guilt
I’ve learned a few things from tracking this over time:
1. Make it a real meal, not just a snack
If you’re going to eat 310 calories, make it count as breakfast. Don’t pair it with a high-calorie drink on top. A black coffee or Americano (5 calories) keeps your total breakfast around 315 calories — totally manageable.
2. Split it
This sounds obvious, but it works well. A croissant splits cleanly in half. Share it, or save the second half. That’s 155 calories with your coffee — a very reasonable morning snack.
3. Track it accurately
The biggest mistake I see is people logging “butter croissant” generically in apps. Generic entries often default to 230–240 calories for a smaller 57g serving. You end up under-tracking by 70+ calories without knowing it. Always search “Starbucks Butter Croissant” specifically in MyFitnessPal or Nutritionix.
4. Treat it as a treat, not a default
Having it every morning adds about 2,170 calories per week from one item. Having it twice a week keeps it enjoyable and special — and saves you 930 calories weekly.
US vs. UK: Why the Numbers Are Different
If you’re in the UK and looking this up, you’ll notice Starbucks UK nutrition data looks slightly different. The Nutracheck UK database lists the Starbucks Butter Croissant at approximately 260 calories — but that’s for the UK product formulation, which may differ slightly in butter content, flour, or serving size from the US version.
The Nutracheck page also notes “not London Area” — because even within the UK, Starbucks products can vary depending on whether they’re baked on-site or supplied regionally.
If you’re in the US, use 310 calories as your benchmark. If you’re in the UK, 259–260 calories is the more accurate figure for the local product.
Tracking Tools That Actually Help
These are the tools I personally use and recommend:
- MyFitnessPal — Best barcode scanner and largest food database. Search “Starbucks Butter Croissant” and look for the official Starbucks entry (310 cal).
- Nutritionix — Great for restaurant foods. Has a reliable Starbucks entry.
- Starbucks App — The most accurate source. Tap any food item in the menu to see full nutrition info directly from Starbucks. This is your ground truth.
- CalorieKing — Good for quick lookups, but double-check the serving size.
- USDA FoodData Central — Best for generic “butter croissant” data if you’re tracking a homemade or non-branded version.
Common Mistakes People Make When Tracking This
Mistake 1: Using a generic croissant entry. Generic croissant entries are often 230–240 calories for a smaller serving. You’ll systematically under-log by 60–80 calories if you do this daily.
Mistake 2: Forgetting the drink. A butter croissant + grande vanilla latte = ~560 calories. People track the croissant but forget to add the drink. Both count.
Mistake 3: Assuming “small pastry = low calories.” Croissants are calorie-dense because of the butter folded into the layers. They look lighter than they are. Per 100g, a butter croissant contains about 364 calories — denser than many chocolate bars.
Mistake 4: Thinking “I’ll just have a croissant instead of a full breakfast.” With only 5g of protein and 1g of fiber, the croissant won’t keep you full. You’re likely to snack more within 2 hours. A more balanced breakfast (eggs, whole grain) keeps you full longer at a similar calorie count.
Pro Tips (From Someone Who Tracks Everything)
- Check the Starbucks app before you order — nutrition data is right there in the menu. No guessing.
- Morning vs. afternoon matters behaviorally. People who eat the croissant as breakfast tend to over-snack later because the protein is low. Pairing it with a protein box (Eggs & Cheese Protein Box: 470 cal but 25g protein) is a better deal nutritionally.
- Warm it up. Starbucks will warm the croissant on request. A warm croissant tastes richer and more satisfying, which can actually help you eat less of it mindlessly.
- If you’re on Weight Watchers, A Starbucks Butter Croissant is approximately 11 WW SmartPoints. Factor that into your daily budget accordingly.
