Pour approximately 1/4 cup of the batter onto the griddle at a time. Cook until golden brown on one side, then flip and cook the second side.
Serve hot with butter, real maple syrup and/or raspberry preserves. Leftover pancakes should be cooled, then stored in ziploc bags in the freezer or refrigerator. They can be reheated in a toaster oven or on a griddle, or microwaved for about 1 minute.
