In a large mixing bowl, stir together the 1 cup unfed starter, flour, maple syrup, and buttermilk.
Cover and let rest at room temperature for about 8-12 hours, or overnight.
Stir the remaining ingredients into the overnight sponge.
Pour batter onto greased, heated waffle iron or griddle until golden brown and slightly crisp.
Serve immediately with melted butter, pure maple syrup, jam, cinnamon applesauce or peanut butter.
