Prepare pans. You can use a 5X9 loaf pan or an 8″ round cake pan. Spray each with cooking spray, or, coat all sides with a thin layer of shortening and dust with flour. Set aside.
Beat eggs and buttermilk until blended. Set aside.
In a large bowl, mix flour, sugar, baking powder and salt together. Stir in raisins.
Slowly add the eggs and milk mixture to the dry ingredients. Stir until a sticky, thick dough forms. You may also choose to mix the dough in the bowl of a stand mixer fitted with the dough hook attachment, or with a hand mixer.
When dough is well blended, place in baking pan (either round pan or loaf pan, whichever you prefer).
Sprinkle a light dusting of flour on top. You may also add a few raisins on top if you prefer.
Bake in preheated oven for 1 hour if using loaf pan or 50 minutes if using an 8″ round pan.
