Heat oven to 425 degrees F. Brush a baking sheet with melted butter or spray with non-stick spray.

Combine dry ingredients in a deep bowl. Gradually stir in 1 cup buttermilk, beating constantly, until dough is firm enough to be gathered into a ball. If dough crumbles, add up to 1/2 cup more buttermilk, 1 tbsp at a time, until it holds together.

Place on a lightly floured board and pat into an 8-inch flattened round loaf.

Place loaf on baking sheet and slash a 1/2-inch deep "X" into the top of the dough with a small, sharp knife.

Bake at 425 degrees F for about 45 minutes, or until the top is golden.

Serve hot.
