Hi! The directions mention adding espresso powder, but it is not listed in the ingredients. How much?

Hi Settie! While the community member who published the recipe would definitely know best here, based on the other ingredients in this recipe, I'd recommend adding a teaspoon of espresso powder. That should be enough to give the cake a bit of a deep, earthy kick without overpowering the rest of the spices. In my mind, you should not be able to identify the coffee flavor when you taste the cake, but just a roasty-toasty undertone. Hope this helps!
