Preheat your waffle iron according to the manufacturer's instructions. If necessary, spray the maker with vegetable oil before making your first waffle and between waffles as needed.
In a small bowl, combine the ground flax meal with 4 tablespoons of room temperature water. Whisk together and set aside. In another, medium bowl, combine the non-dairy milk and lemon juice or vinegar. Stir them and set them aside. + In a large mixing bowl, whisk together the flours, baking powder and soda, salt, cinnamon, and sugar.
In a large mixing bowl, whisk together the flours, baking powder and soda, salt, cinnamon, and sugar.
To the non-dairy milk and vinegar mixture, add the melted vegan butter, applesauce, and the prepared flax + water mixture. Stir these ingredients well. Pour them into the large mixing bowl with the dry ingredients. Fold everything together until the wet and dry ingredients are well mixed. A few small lumps in the batter is OK, but keep mixing (or use a whisk to mix) if you see larger lumps or dry streaks of flour. You’ll have a relatively thick waffle batter. Fold in the chopped apples.
If using a 4-slice, square or round waffle maker, add a cup of batter to the waffle maker. Cook the waffle according to the manufacturer's instructions. If using a round, mini waffle maker, drop the batter in 1/4-cup amounts into the maker and cook according to the manufacturer's instructions. Continue this process until you’ve run out of batter.
To keep the waffles warm during preparation, place them on a parchment or foil lined baking sheet in a preheated 350F oven as you work.
When all of the waffles are ready, serve them with your toppings of choice. Enjoy!
