In a medium mixing bowl, combine the flour, baking powder, salt, and sugar, and stir to combine.
Make a well in the center of the dry ingredients, and add the eggs, oil, applesauce, and milk.
Whisk all ingredients together until a thin and slightly lumpy batter forms.
Pour the batter into your waffle iron according to manufacturers directions.
When the waffle is done cooking, carefully place it on a wire rack to cool, taking care not to stack the waffles on top of each other. Repeat with remaining batter.
Serve waffles hot with your favorite topping, such as buttermilk syrup, strawberries, and whipped cream.
Notes
If you don't have applesauce, you can replace it with oil. I often have it on hand and like the added sweetness and moisture it brings to the waffles, but you can use what you have on hand.
Waffles freeze beautifully. Place them in a zip-top freezer bag and store up to two months. Reheat them in the toaster or oven.
Be sure to pre-heat your waffle iron so that the waffles come out golden.
Grease your waffle iron with a little cooking spray, butter, or oil in between each waffles to prevent sticking.
