Unsweetened Baking Chocolate (Best Option)
1 ounce baking chocolate = 3 tablespoons cocoa powder + 1 tablespoon butter or oilUnsweetened baking chocolate contains cocoa solids and cocoa butter, making it the closest match to cocoa powder in flavor and color. Since it has fat, adjusting the fat in the recipe by reducing butter or oil helps maintain dough consistency.
For best results, finely chop or melt the baking chocolate and incorporate it evenly into the dough to avoid pockets of fat or uneven chocolate distribution.
The final scones will have a richer, slightly denser texture but retain the classic chocolate flavor and crumb structure similar to using cocoa powder.
