Calories in Starbucks Viennesse Swirl add up to 361 per piece, which is more than the pretty piped buttercream and chocolate drizzle let on. Picture the pastry case on a slow Tuesday morning: croissants on one side, and tucked in the corner, the Viennese Swirl looking almost too good to eat. It’s richer than it looks — 21g of fat, with 13.4g of that saturated, which puts it closer to a dessert than a breakfast pastry.
It’s vegetarian, made with wheat, milk and egg, and the sugar count (23.7g) sits mid-range for the bakery case — sweeter than a plain croissant, less sweet than most cakes. Protein is basically an afterthought here at 3.7g.
If you like the buttery layers of the Caramel Waffles, this has a similar texture with more sweetness up front. It’s a step up in richness from the Teaser Slice, and honestly less indulgent than the Chocolate & Hazelnut Brookie if you’re trying to pick the lesser evil.
