In a small bowl, combine the milk, apple cider vinegar, and a splash of vanilla. Let it sit for 5 minutes.
In a larger bowl, combine the dry ingredients (flour, protein powder, baking powder, cinnamon, salt).
Add the coconut oil and maple syrup to the milk mixture and stir. Pour the wet ingredients into the dry ingredients and stir until just combined. Add shredded carrots and stir again.
Grease a heated waffle iron and add the batter. If you want mini waffles, add about 1/4 cup of batter. For larger waffles, add closer to 2/3 cup.
Top with your fav toppings! If you are making the cream cheese icing, here is how we make that: Combine the cream cheese and sugar. Add splashes of milk until you get the consistency you want. Enjoy!
