Pre-heat oven to 350F degrees. Place parchment on a baking sheet, or lightly grease and set aside.
In a large mixing bowl or in the bowl of a stand mixer, place in the order listed, flour, sugar, baking powder, baking soda, and salt . Add the raisins and give everything a quick whisk.
3 cups all-purpose flour, ½ cup granulated sugar, 1 Tbsp Baking Powder, ½ tsp Baking Soda, ½ tsp salt, 1 ½ cups raisins
Add buttermilk and on low speed, mix until it forms a soft dough, about 30 seconds. You can do this by hand if you like. There will/may be some dry ingredients and possibly a few raisins that just won't mix in. That is fine.
1 ½ cups buttermilk
Turn dough out onto a lightly floured surface and knead just until it's a smooth ball, only another 20-30 seconds.
Place the ball of dough onto the baking sheet and press to spread and flatten the dough. Slash the top with a sharp knife. Pat the top with some of the excess flour. This will give the bread a nice rustic finish.
Bake for 40-45 minutes, until bread is just golden.
Remove from oven and let cool for 15 minutes before slicing.
Serve with softened butter.
