Turn your waffle iron on and spray with non-stick cooking spray. Let heat up.

In a high-speed blender, add the cooked sweet potato, cassava flour, avocado oil, dairy-free milk, baking soda, baking powder, ground cinnamon, apple cider vinegar, and sea salt. Place the lid on the blender and blend on low for 30 seconds. Scrape the sides of the blender, and blend again for 10-15 seconds or until all batter is mixed together.

Remove the blender from the base and remove the lid and blade. Scoop out enough waffle batter to fill your waffle iron (amount will vary depending on the type of waffle iron you have.) Close the lid of the waffle iron and let cook. Once the waffle is done cooking, remove from the iron. Continue this process until all waffle batter is used up.
