Sour Cream Waffles

1 cup whole milk
 1 cup sour cream
 2 eggs
 3 tablespoons butter, melted
 1 teaspoon vanilla
 2 teaspoons baking powder
 1 ½ cups all purpose flour
 1 teaspoon baking soda
 ½ teaspoon cinnamon
 Pinch kosher salt

 Heat waffle iron. Combine wet ingredients and whisk well to combine. Sift dry ingredients into a large bowl and form a well in the center. Add the wet mixture to the well and fold in with the dry. Don't worry if there are a few lumps. When iron is hot, spray lightly with non-stick spray. Spoon ½ to ¾ cup of batter onto the center of the iron and cook until a golden brown crust forms, about 3 to 5 minutes.
