A 1-ounce square (about 28 g) of 70–85% dark chocolate provides roughly 170 calories and is rich in flavonoids, per USDA FoodData Central. It satisfies a sweet craving in a small amount and has more antioxidants than milk chocolate — but it’s still calorie-dense, so measure a square or two. Use it to replace, not add to, other desserts. Higher cacao % means less sugar.
