Preheat the oven to 350°F. Lightly grease an 8x8-inch baking dish.
Mill 98 g soft white wheat berries on the lowest setting of your grain mill.
In a bowl, mix together freshly milled flour, cocoa powder, and salt. I like to sift in the cocoa powder to remove any clumps.
Melt the butter in a saucepan over low heat. Stir in sugar. Remove from heat and add vanilla.
Beat the eggs one at a time until fully combined.
Add in the dry ingredients until just blended. Fold in chocolate chips.
Spread into the pan and bake 25–30 minutes, until edges pull from sides. (Mine takes 25 minutes.)
Cool completely before slicing.
