Weigh your wheat berries and then grind them with your mill. Remember that wheat berries have the same weight as wheat flour.
Heat your waffle iron to medium-high heat.
Mix milk and ACV for at least 5 minutes to properly start to curdle. If you are using buttermilk their is no need to do this step.
In a large bowl, whisk together the whole wheat flour, baking powder, baking soda, brown sugar and salt.
In another bowl, whisk together eggs, milk mixture, melted butter, and vanilla extract until well combined.
Pour the wet mixture into the dry ingredients, stirring with a dutch whisk just until combined.
Let the batter rest for 10 minutes or up to 48 hr (refridgerated). This allows the flour to hydrate properly and results in a better texture.
Cook waffles per instructions of your waffle iron. Enjoy!
