Unsweetened chocolate substitute

Chocolate and cocoa · Checked against 4 sources · Updated November 4, 2026

Quick answer

For each 1 ounce square of unsweetened chocolate, use 3 tablespoons of cocoa powder plus 1 tablespoon of butter or oil. Melt the fat first, then stir in the cocoa. Check the sugar: cocoa has none, same as unsweetened chocolate, so the recipe's sugar stays as written.

Can I use semisweet?

Not 1 for 1. It already has sugar, so cut some sugar from the recipe.
