In a large bowl, or in the bowl of your heavy-duty mixer, combine and mix all the dry ingredients.
In a medium bowl beat the eggs. Add the buttermilk to the eggs and whisk well. Pour the wet ingredients into the dry ingredients and mix well.
Turn the dough out onto a floured surface and form into a round mound, using additional flour to coat the dough so it's sticky on the inside and handle-able on out outside.
Place the dough on a baking pan and score a big "X" on the top with a knife.
Bake for 30-40 minutes. Best when served while still warm and with plenty of butter.
