the trick to the coffee when I use it is (usually) to use too little for anyone to detect coffee-flavour, but enough to alter how other flavours interact with each other. You can use maple in people-look-at-you-funny ways similarly

I've found that cinnamon can be used in the same sort of way. The trick is to use enough that the flavors interact, but not enough that anyone who tastes it will say "hey, you put cinnamon in that".
