In a medium-sized bowl or mixer, combine together milk, egg, butter, and salt.
Add flour, sugar, vanilla, and baking soda. Mix together until combined and batter is smooth and lump-free.
Pour 1/3 cup batter into waffle iron and bake on medium-low heat.
Remove from waffle iron.
Eat right away or allow to cool before freezing.
Freeze 4-6 in each 1 gallon ziploc bag.
Notes
To reheat after freezing - Place in cold oven directly on rack. Turn oven to 375 degrees. Once the preheat cycle is complete, remove waffles from oven and enjoy! *Heat times may vary by oven.
