In a small bowl or liquid measuring cup, combine the milk and 2 tsp of apple cider vinegar. Let this rest of 10 minutes. This creates a dairy-free "buttermilk" to be used for the pancakes.
While the milk is resting, peel and grate your apples, then mix them with ½ tsp of the cinnamon.
In a separate, small bowl, whisk together the flour, cinnamon, baking powder, nutmeg, allspice, and salt. Set this aside to start.
In another bowl, whisk together the egg, coconut oil, maple syrup, and vanilla. Then slowly add in the milk mixture, whisking continuously to combine.
Next, add the flour mixture. Whisk it into the wet ingredients until just combined and you no longer see streaks of white. Any more, and you'll end up with tough pancakes.
Carefully fold in the grated or finely chopped apples.
Heat a nonstick skillet or pancake griddle on medium heat. To test if it's ready, add a drop of water to the skillet. If it sizzles and evaporates, then your pan is hot enough!
Grease the skillet or griddle with nonstick spray, and then scoop out ¼ cup portions of the batter. Cook on one side until you start seeing bubbles, then flip and cook for another 45 seconds-1 minute (or as long as needed to be cooked through).
Serve with maple syrup or honey and enjoy!
