Overnight Waffles
1 3/4 cups milk (any kind - I've used skim, 1%, and whole)
6 Tbsp unsalted butter
1 cup whole wheat flour (or white whole wheat flour)
1 cup all-purpose flour
1 Tbsp sugar
1 1/2 tsp instant yeast
1 tsp salt
2 eggs
1 tsp vanilla extract
Heat the milk and butter together in a small saucepan over medium heat until the butter is melted. Let cool until just slightly warm.
Whisk together the flours, sugar, yeast, and salt in a large bowl. Whisk in the warm milk until smooth. Whisk in the eggs and vanilla until smooth. Scrape down the sides of the bowl and cover with plastic wrap. Refrigerate for at least 12 hours.
Heat the waffle iron. Remove the batter from the fridge (it should have about doubled in size) and whisk to recombine and deflate. Make waffles according to your waffle maker's instructions.
If there are leftovers, they heat up excellently in the toaster the next day!
