Preheat your oven to 350°F (175°C). Grease or line a 9x5-inch loaf pan with parchment paper.
Mill 1 cup + 2 tablespoons soft white wheat berries to make about 1 1/2 cups freshly milled flour.
In a large mixing bowl, mash 3 ripe bananas until smooth using a fork or potato masher. Stir in 1/3 cup melted unsalted butter until combined. Mix well. Add 1/2 cup of sugar. Stir in 1 egg and 1 teaspoon vanilla extract until fully incorporated.
In a separate bowl, whisk together: 1 1/2 cups freshly milled soft white wheat flour, 1 teaspoon baking soda,1/2 teaspoon salt
Gradually add the dry ingredients to the banana mixture, stirring until just combined. Do not overmix; a few lumps are perfectly fine. Fold in 1 cup chocolate chips.
Let the batter sit for 15–20 minutes before baking. This allows the freshly milled flour to fully absorb the moisture, giving the banana bread a softer texture and better crumb.
Pour the batter into the prepared loaf pan and spread evenly. Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean. Let cool before slicing.
