For an extra layer of flavor, try adding a sprinkle of chia seeds or flaxseed meal to the batter. Ensure the skillet is properly heated before adding the batter to achieve a golden-brown exterior. To keep the pancakes warm while cooking the remaining batter, place them in a preheated oven at 200°F (93°C). Store leftover pancakes in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave before serving.
