Calories in Starbucks S’mores Muffin

Calories in Starbucks S’mores Muffin come in at 449 per piece, with 36g of sugar — heavier than it looks, this one packs graham, chocolate, and marshmallow into a muffin shell, adding up fast to the highest sugar count of the muffins I’ve tried here.

It’s vegetarian, and the allergen list is shorter than most bakery items at just wheat and milk. The marshmallow swirl on top is the standout part, genuinely gooey rather than just decorative. At 20.4g of fat, it’s a proper treat rather than a breakfast muffin.

Compared to the Blueberry Muffin, this is a different category entirely — more dessert than breakfast bread. If you want a loaf with similar richness, the Carrot Cake Loaf is worth a look. And for something savory to balance it out, the Ham And Cheese Croissant is the opposite end of the case.
