Preheat your oven to 425?F (220?C).

Mix the dry ingredients in a large bowl: flour, baking soda, salt, and sugar. Stir until evenly combined.

Create a well in the center of the dry mix. Pour in the buttermilk gradually while stirring gently with a wooden spoon, forming a sticky dough.

Knead the dough on a floured surface for about 1-2 minutes until it comes together.

Shape the dough into a round loaf about 1? inches thick. Place it on a parchment-lined baking sheet, and score a deep 'X' on top.

Bake for 30-35 minutes until golden brown and sounds hollow when tapped on the bottom.

Cool the bread on a wire rack for at least 10 minutes before slicing.
