Add the applesauce, gluten free oats, eggs, almond milk, vanilla extract, cinnamon, maple syrup, ghee, and baking powder to a high-powered blender.
Blend until the batter is completely smooth.
Next, add the grated apple to the batter and stir until well combined.
Allow the batter to rest for a few minutes. This will allow the oats to soak up some of the moisture. While your batter is resting, heat your waffle maker. (I heated mine to level 4 on my waffle maker).
Once the waffle maker is heated, spray it with a little non-stick spray (I used avocado oil non-stick spray), fill the waffle maker with batter, close the lid and let cook until the waffle is golden brown and beginning to crisp. This takes 5-6 minutes in my waffle maker. Once the steam stops coming out from the sides of the waffle maker, I like to check for doneness.
Transfer the cooked waffle to a wire cooling rack or baking sheet.
Repeat this process until all of the waffle batter has been cooked. Be sure to give the waffle maker a quick spray of oil before adding a scoop of new waffle batter each time.
Serve the waffles with additional toppings like fresh apple slices, powdered sugar, and maple syrup. Enjoy!
