- 2 1/4 cups all-purpose flour, sifted
- 1 1/2 cups coarsely ground whole wheat flour
- 3 tablespoons sunflower seeds
- 1 teaspoon baking soda
- 1 pinch salt
- 1 1/4 cups buttermilk
- Preheat oven to 400 degrees F (200 degrees C). Dust a baking sheet lightly with flour.
- Mix all-purpose flour, whole wheat flour, sunflower seeds, baking soda, and salt together in a large bowl. Pour in buttermilk; mix until a soft dough forms.
- Turn dough out on a floured work surface and knead until smooth. Shape into a round loaf; cut an X in the top. Transfer to the floured baking sheet.
- Bake in the preheated oven until loaf is golden brown and sounds hollow when tapped on the bottom, about 40 minutes. Let cool for 30 minutes before slicing.
