Katmer is a signature dessert of Gaziantep, made by stretching dough into paper-thin layers, then filling it with plenty of butter, clotted cream (kaymak), and ground pistachios. It is baked or griddled until crisp, dusted with powdered sugar, and usually served warm, traditionally at breakfast or as an afternoon sweet. The biggest factors driving its calories are the amount of butter brushed onto the pastry, how generous the clotted cream is, and the ratio of pistachios. A thin, simple homemade slice and a bakery-style piece loaded with cream can differ dramatically in energy.

When you look at the nutrition breakdown, katmer leans heavily on fat and carbohydrates. Per 100 grams it averages about 8 g protein, 40 g carbohydrate, and 25 g fat, while fiber stays low at around 2 g. Most of the fat comes from the butter and clotted cream, with pistachios adding both fat and a little plant protein. That combination makes katmer satisfying but calorie-dense.

How Many Calories Are in Katmer?

The calories in a piece of katmer depend on how big your portion is. A standard slice (1 slice, 80 g) has about 320 kcal. A larger bakery-style plate, 1 serving (160 g), climbs to roughly 640 kcal. If you would rather count on a per-100-gram basis, katmer averages about 400 kcal. A thin homemade version made with less butter and clotted cream will land noticeably lower in calories than a cream-heavy portion served at a bakery.

Can You Eat Katmer on a Diet?

Because katmer is dense in both calories and fat, it is not completely off-limits on a diet, but it is a treat to enjoy in moderation. Since 1 slice (80 g) delivers about 320 kcal, a smart approach is to satisfy a sweet craving with a small slice and keep the rest of your day's calories in balance. Splitting a piece, pairing it with unsweetened tea, and steering clear of other high-fat foods that day all help keep the portion in check. This is general information; for a nutrition plan tailored to you, it is best to consult a professional.

How Do the Pistachios and Clotted Cream Change the Calories?

Katmer gets its character from its filling, and that filling is also the main reason it is so calorie-heavy. A generous amount of pistachios adds flavor and a bit of protein, but it also pushes up the fat content; much of the 25 g of fat in 100 g of katmer comes from the pistachios, butter, and clotted cream. A thinner version with less cream stays around 320 kcal per 1 slice, while thick, filling-packed versions can go higher. In that same portion, the protein side sits at only about 6.4 g, so while katmer is genuinely satisfying, it is best thought of as an indulgent dessert rather than a real protein source.
