My mother-in-law got me a waffle iron for my birthday and the recipes that came with it are awesome. This one is my favorite.
You need to start this batter the night before you want to have the waffles unless you are having breakfast for dinner and then you need to make the batter in the morning.
1/2 cup warm water
1 Tbsp. white sugar
2 1/4 tsp. yeast
2 cups whole milk or whatever you have.
1/2 cup butter melted and cooled
1 tsp. salt
2 cups flour
2 large eggs, beaten
2 tsp. vanilla extract
1/4 tsp. baking soda.
The night before, combine the water, sugar, and yeast. Let this sit until the yeast becomes foamy. Add the milk, melted butter, and salt. Then add the flour. Cover your bowl with plastic wrap and let it stand. Don't refrigerate it.
In the morning add the rest of the ingredients. Then follow the instructions on your waffle iron to cook them.
