Unsweetened chocolate substitutes: 3 swaps and how the nutrition changes
To replace 1 oz (1 square) of unsweetened baking chocolate, use 3 tbsp cocoa plus 1 tbsp butter, 3 tbsp cocoa plus 1 tbsp oil or 3 tbsp cocoa plus 1 tbsp margarine. 1 oz (1 square) of unsweetened baking chocolate has 182 calories, and the swaps come to 139 to 157 calories for the same amount.

Which swap fits what you need
Per 1 oz (1 square), among the swaps above.
- Fewest calories: 3 tbsp cocoa plus 1 tbsp margarine, 139 calories (182 calories in unsweetened baking chocolate)
- Least saturated fat: 3 tbsp cocoa plus 1 tbsp oil, 3.4 g (9.2 g in unsweetened baking chocolate)
- Least sodium: 3 tbsp cocoa plus 1 tbsp oil, 3.4 mg (6.8 mg in unsweetened baking chocolate)
Choosing a swap
Three tablespoons of unsweetened cocoa plus 1 tablespoon of fat replaces 1 oz of unsweetened baking chocolate.
Any of the three fats works. Calories drop from 182 to between 139 and 157. Oil or margarine cuts saturated fat from 9.2 g to about 3.5 g. Butter keeps it closer, at 7.8 g.
Butter and margarine add some sodium, which matters little at 1 oz but adds up in a large batch.

How we calculate: each part of a swap is converted from its household measure to grams with the USDA portion weight for that food (1 cup = 16 tbsp = 48 tsp), then multiplied by the USDA values per 3.5 oz (100 g). Water counts as zero, and so do pinches under 5 g (salt, baking powder) where USDA lists no value. A dash (—) means USDA reports no value for at least one part. How we verify.
