For overnight waffles:
- Combine flour, sugar, oil, sourdough starter, milk, butter, and vanilla in a large mixing bowl to make a thick batter
- Cover, and let sit at room temperature overnight
- In the morning, whisk in eggs and salt
- Heat waffle iron, and bake waffles according to waffle iron instructions. Mine lights up when it’t hot enough, takes 1/3 cup of batter per waffle, and lights up again when the waffle is done.
For quick or sourdough discard waffles:
- Combine flour, sugar, baking soda and salt in a large mixing bowl
- Whisk eggs, and add to dry ingredients along with butter, sourdough starter, milk, and vanilla
- Stir until just combined, and cook according to waffle iron instructions.
Enjoy!
