Does anyone know how to make normal cupcakes into chocolate ones?? I have the recipie for normal cupcakes but I don't know how much coco powder to add and when to add it? If you could put the answer in grams it would help a lot as I only know the British grams measurements thanks xxxx

Im not about to guess the cocoa needed for your recipe but the second link gives you a good clue to how much but you could always just get a chocolate cupcake recipe.
