I'm wondering if my chocolate cake will taste yummy if I use dark coffee from dunkin donuts or should I buy the packets from the grocery store and boil it myself. I am not a coffee drinker so I have none in the house.
Also, does it have to be hot when pouring it in the batter?
One more question...if I use 1 cup of buttermilk in my batter already, should I substitute some of that milk for coffee or just add about 1/2 cup in addition to. I'm so nervous to use coffee.
ANy help is much appreciated!
