Preheat your waffle iron.
Combine by whisking together; oat flour, baking powder, sea salt and cinnamon in a large mixing bowl, then set aside.
In another mixing bowl, whisk together milk, coconut oil, eggs, maple syrup and vanilla extract. Whisk until your mixture is creamy.
Next, make a well in your dry ingredients.
Pour your liquid mixture into the well and gently fold until all the ingredients are well combined.
Let your batter stand at room temperature for about 10 minutes.
Ladle about 1/2 cup of the prepared batter into your preheated waffle iron.
Cook the waffles until golden and crisp, about 2-3 minutes.
Garnish with fresh berries and serve immediately with additional maple syrup, or raw honey if desired.
