This cake actually improves in flavor when made 1-2 days in advance, as the spices have time to meld. Unsweetened, homemade applesauce with a chunky texture provides the best flavor and moisture. Add 1 cup of diced fresh apples tossed in 1 tablespoon of flour for extra texture and flavor. Store unfrosted cake in an airtight container at room temperature for up to 3 days, or refrigerate frosted cake for up to a week.
