For an extra layer of flavor, consider adding a handful of chocolate chips, chopped pecans, or a sprinkle of cinnamon to the batter before cooking. Ensure your waffle iron is sufficiently hot before pouring in the batter for optimal crispness. If the batter seems too thick, add a splash more almond milk until desired consistency is achieved. Waffles are best served immediately. However, you can keep them warm in a preheated oven (at a low temperature) until ready to serve. Feel free to substitute other plant-based milks (such as soy or oat milk) for almond milk.
