I have a recipe of Old Fashioned Donuts that I love... I would like to add some Cocoa Powder to the recipe, but I don't know how to do that and keep the percentages correct. Basically, I don't know if adding Cocoa Powder will muck up the percentages the same as say adding more flour.
The Current Recipe is as follows:
- 600 g Flour
- 12 g Kosher Salt
- 90 g Egg Yolk
- 30 g Unsalted Butter
- 15 g Baking Powder
- 380 g Sour Cream
As a bonus... how much cocoa powder for a recipe like this would be appropriate? I'm kind of new to baking.
