4 Tbsp butter, softened at room temperature
1/2 cup granulated sugar
4 cups all-purpose unbleached flour
4 tsp baking powder
1-1/2 tsp baking soda
3/4 cup golden raisins
2 Tbsp ground cardamom
2-1/2 cups buttermilk
Preheat oven to 350°F. Coat a Bundt pan (or two loaf pans) with baking spray, and set aside.
In a large mixing bowl, cream together the butter and sugar with a wooden spoon. Stir in the flour, baking powder and baking soda, and blend all together.
Add the raisins, cardamom and buttermilk. Stir to combine, but don't overmix. Pour the batter into the prepared Bundt pan or loaf pans.
Bake at 350F for 40 minutes (if using loaf pans, check at 30 minutes). Let cool 10 minutes in the pan, then turn onto a cooling rack and let cool completely. (Can be frozen.)
