For an even richer flavor, try using dark chocolate chips or adding a tablespoon of instant coffee powder to the chocolate batter. If you don't have buttermilk, you can make a quick substitute by adding 1 tablespoon of white vinegar or lemon juice to a liquid measuring cup and filling it with milk to the 1-cup line. Let it sit for 5 minutes before using. Be careful not to over-mix the batter once you add the flour, as this can result in a tough cake. Store leftover cake in an airtight container at room temperature for up to 3 days.
