Unsweetened Cocoa Powder with Butter (Best Option)
1 tablespoon cocoa powder + 1 tablespoon melted butter per 1 ounce dark chocolateUnsweetened cocoa powder provides the concentrated chocolate flavor without added sugar, while butter replaces the fat content lost by omitting solid chocolate. This combination mimics the melting and flavor release properties of dark chocolate in the dough.
For best results, mix the cocoa powder thoroughly with the melted butter before incorporating into the dough to ensure even distribution. Monitor dough hydration as cocoa powder can absorb moisture, and adjust water slightly if needed.
The final focaccia will have a rich chocolate aroma and moist crumb similar to using dark chocolate, with a slightly more pronounced cocoa bitterness that complements the bread's savory notes.
