Preheat your waffle maker: Get it nice and hot to ensure those waffles come out crispy and golden.
Mix all dry ingredients: In a mixing bowl, combine the flour, salt, cornstarch, and baking powder. Stir well to ensure even distribution.
Combine the wet ingredients: In a separate bowl, whisk together the milk, apple cider vinegar, honey, and olive oil until fully combined.
Combine wet and dry ingredients: Slowly add the wet mixture to the dry ingredients. Mix gently until well combined, making sure not to over-mix (a few lumps are okay!).
Cook the waffles: Pour about 1/2 cup of batter into your preheated waffle maker and cook until they are golden brown and crisp.
Prepare the topping: While the waffles cook, mix the sugar and cinnamon in a bowl. Melt the butter in a microwave-safe dish.
Serve and enjoy: Once your waffles are ready, dip them in the melted butter and sprinkle them liberally with the cinnamon-sugar mixture. Serve warm and enjoy!
