Melt the butter and let it sit for a few minutes before adding it to the batter. Preheat your waffle maker so it’s ready when the batter is mixed.
Mill the soft white wheat berries until you have about 2¼ cups of fresh flour.
In a medium bowl, whisk together the freshly milled flour, baking powder, sugar, and salt.
In a large bowl, whisk the eggs. Add the milk, melted butter, and vanilla, mixing until smooth.
Add the dry ingredients to the wet ingredients and stir just until combined. Do not overmix.
Pour batter into the preheated waffle maker (about ½ cup per waffle, depending on your machine). Spread gently so it fills the wells and cook until set. If you prefer a firmer texture, cook slightly longer.
Carefully remove the waffles and serve right away with your favorite toppings.
