In a bowl, combine oat flour, baking powder, cinnamon and salt. Mix until well combined. Set aside.
In a separate large bowl, combine coconut oil, vanilla extract, Greek yogurt and unsweetened vanilla plant-based milk of choice. Mix well.
Pour the dry ingredients into the bowl with the wet ingredients and mix well.
Fold in the grated carrots and chopped walnuts.
Spray a large pan with cooking spray. Let pan warm on medium heat. Add 1/4 cup of batter per pancake, and let cook for about 3-4 minutes, until the sides are bubbling. Use a spatula to flip the pancakes and cook for about 2-3 minutes on the other side. Repeat as needed for remaining pancakes.
Serve immediately. Optional to top with more maple syrup, chopped walnuts and/or grated carrots. Store leftover pancakes in an airtight container in the refrigerator for 3-4 days.
