To begin, in small bowl add your vinegar and milk. Set it aside for several minutes for the milk to curdle and become "buttermilk."
Preheat a large pan (or skillet) to medium heat.
In a large mixing bowl add your flour, baking powder, baking soda and salt and stir them together.
In a small mixing bowl, add your maple syrup and coconut oil and whisk them together. Next, add your "buttermilk" (milk and vinegar mixture) and egg and whisk them in.
Now pour your wet ingredients into your dry ingredients and whisk them together till they're well combined. If your batter is too thick you can add another 1-2 tbsp of milk if you'd like.
With large spoonfuls, scoop the batter onto your pan forming several pancakes and cook each pancake on one side till you start to see bubbles gently forming. Then flip the pancakes and cook them on the other side for a few more minutes till they're cooked through. Continue till all of your pancakes have been cooked through.
Devour!
Stored in an airtight container in the fridge these pancakes will last about 4-5 days. You can also freeze these for up to 2 months.
