Can I dust a cake pan with cocoa powder instead of flour?
Yes, for chocolate cakes, it’s fine (and sometimes desirable) to dust the pan with cocoa powder as you would use regular wheat flour. This is a good tip also for converting recipes to gluten-free. Simply add a spoonful of cocoa powder to the greased pan, roll it around, shaking the pan to ensure an even layer of powder, then tap out any excess.
