For extra flavor, try adding a pinch of ground nutmeg or cloves to the batter. Feel free to substitute maple syrup or honey for the granulated sugar. These pancakes are also delicious with chopped nuts, chocolate chips, or berries added to the batter. To keep pancakes warm while cooking the rest of the batter, place them on a wire rack in a preheated 200°F oven. Leftover pancakes can be stored in an airtight container in the refrigerator for up to 3 days or frozen for longer storage. Reheat in a toaster, microwave, or skillet.
