What Is Freshly Milled Flour?

Freshly milled flour comes straight from whole wheat berries that you grind at home using a grain mill. This process keeps all the natural nutrients, oils, and flavor intact.

When you bake with fresh milled flour, you get:

  • Better flavor
  • More texture
  • A wholesome, hearty bite

For this recipe, soft white wheat works best because it creates a lighter, more tender cookie.
