Preparation Steps

• Preheat your oven to 425°F (220°C). Grease and lightly flour a baking sheet or a 9-inch round cake pan.
• In a large bowl, whisk together the whole wheat flour, all-purpose flour, baking soda, salt, and sugar (if using).
• Make a well in the center of the dry ingredients and pour in the buttermilk. Mix with a wooden spoon or your hands until just combined. The dough will be sticky.
• Turn the dough out onto a lightly floured surface and gently shape it into a round loaf. Do not overwork the dough.
• Place the loaf on the prepared baking sheet or in the cake pan. Cut a deep cross into the top of the loaf with a sharp knife. This helps the bread bake evenly.
• Bake for 15 minutes at 425°F (220°C), then reduce the oven temperature to 375°F (190°C) and bake for another 25-30 minutes, or until the bread is golden brown and sounds hollow when tapped on the bottom.
• Remove the bread from the oven and immediately brush the top with melted butter.
• Let the bread cool on a wire rack for at least 30 minutes before slicing and serving.
