Tiramisu Calories: How Many Calories Per Slice?
Real calorie data for tiramisu from a tested classic Italian recipe, broken down by slice size and portion.
Tiramisu's calorie count is driven almost entirely by the mascarpone and sugar in the cream layer — the ladyfingers and coffee soak contribute comparatively little. Restaurant and bakery slices vary in size and mascarpone-to-cream-cheese-substitute ratio (some cut costs with cream cheese blends), which shifts the number from bakery to bakery. This guide uses our tested classic tiramisu recipe's real nutrition data.
At a Glance
Per our tested Classic Tiramisu (Italian Coffee Mascarpone Dessert) recipe, one slice (160g, from a recipe serving 8) is 480 calories, with 9g protein, 38g carbohydrate, 32g fat, and 1g fiber. The near-total absence of fiber and the high fat content reflect the dish's mascarpone-and-egg-yolk-based cream — this is a genuinely rich dessert, not a light one.
Why the Number Varies
Mascarpone quantity is the dominant factor, since mascarpone is roughly 45-50% fat by weight — recipes and bakeries that use more cream layer relative to ladyfingers will run higher. Sugar in both the zabaglione and the whipped egg whites is the second factor; some recipes reduce sugar for a less sweet result, trimming calories modestly. Slice size is the most practical variable for the eater: bakery slices are frequently cut larger than a home-portioned eighth of a pan, since tiramisu is dense and a generous-looking slice can weigh considerably more than 160g.
Portion Size: How the Calories Scale
Using our recipe's 480-calorie, 160g slice as the baseline: a small slice (100g): approximately 300 calories. A standard slice (160g, one-eighth of the recipe's pan): 480 calories. A generous bakery or restaurant slice (220g, common for a dessert marketed as a 'signature' item): approximately 660 calories. A small tasting portion (60g, a few spoonfuls): approximately 180 calories.
💡 Tip: If sharing a bakery tiramisu slice, splitting it in half brings a typical large slice down to roughly the same calorie range as a standard home-cut portion.
How Tiramisu Fits Your Goals
Tiramisu is high in fat and sugar with essentially no fiber, making it a poor fit for an active calorie-deficit day — better reserved for a maintenance day or a planned treat. It's not compatible with keto or low-carb eating given the 38g of carbs per slice, mostly from sugar. For diabetic eating, the fat content slows sugar absorption somewhat compared to a purely sugar-based dessert, but the overall sugar load is still significant and portion control matters most here.
Calculate Your Exact Portion
Since tiramisu slice sizes vary so much between home, bakery, and restaurant servings, use our portion calculator to scale this recipe's per-100g nutrition (roughly 300 calories, 5.6g protein, 24g carbs, 20g fat per 100g) to your actual slice weight for an accurate figure.
A Lighter Version, If You Want One
The most effective calorie reduction for tiramisu is folding in slightly less mascarpone relative to whipped egg whites — the whites already provide the airy texture, so a modestly leaner cream (75% mascarpone instead of the traditional full amount, with light cream cheese making up the difference) trims fat while keeping a recognizably rich result. Reducing the sugar in the zabaglione by about 15-20% is barely noticeable given the coffee's bitterness balancing it.

Frequently Asked Questions
How many calories are in a slice of tiramisu?
Per our tested recipe, a standard slice (160g, one-eighth of the pan) is 480 calories. A generous bakery-style slice (220g) can run closer to 660 calories, since restaurant portions are often cut larger than a home-portioned slice.
Is tiramisu healthy?
Not particularly — it's high in fat and sugar with almost no fiber, since it's built on mascarpone, egg yolks, and sugar. It does contain some protein and calcium from the mascarpone and eggs, but it's best understood as an occasional dessert rather than a nutritionally beneficial food.
Is tiramisu good for weight loss?
It's a poor choice on an active deficit day given its calorie density (480 calories per slice) and low fiber content. If you want to include it occasionally, a smaller slice (100g, about 300 calories) or splitting a restaurant portion keeps it more manageable within a daily calorie budget.
How much sugar is in tiramisu?
Our tested recipe's slice has 38g of total carbohydrate, most of which is sugar from the zabaglione, whipped egg whites, and any sweetened coffee liqueur used. That's comparable to roughly 9-10 teaspoons of sugar equivalent per slice.
A standard slice of our tested classic tiramisu (160g) is 480 calories, driven mostly by the mascarpone-based cream layer rather than the ladyfingers or coffee. It's an inherently rich dessert best treated as an occasional indulgence, and slice size — which varies a lot between home and bakery portions — is the main lever if you're managing intake.
