Preheat your waffle iron. In a measuring cup, combine the almond milk and apple cider vinegar. Layer all ingredients in a blender in the order listed. It’s very important to put the wet ingredients on the bottom for proper blending. Blend on high until smooth, for about 10 seconds. If you’d like to add nuts or chocolate chips, stir them in by hand now.Pour the batter into the waffle iron and cook until crispy on the edges, about 10 minutes. Remove from iron and set aside to cool for a few minutes. Serve warm with pure maple syrup and enjoy!
