The Enchantetd Plum Cake

1/2 teaspoon baking soda
1 teaspoon cinnamon powder
1/2 teaspoon nutmeg powder
1/2 teaspoon salt
1 cup unsalted butter, softened
1 cup brown sugar
1/2 cup granulated sugar
4 large eggs
1 cup buttermilk
1 cup chopped dried plums (or prunes)
1/2 cup raisins
1/2 cup chopped walnuts (optional)
Zest of one lemon
Zest of one orange
1 teaspoon vanilla extract
1/4 cup rum or brandy (optional)
Instructions
Preheat your oven to 350°F (175°C) and grease a bundt or loaf pan.
In a medium bowl, sift together the all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.
In a large mixing bowl, cream the softened butter, brown sugar, and granulated sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract and citrus zests.
Gradually add the dry ingredients to the creamed mixture, alternating with the buttermilk, beginning and ending with the dry ingredients.
Gently fold in the chopped dried plums, raisins, and walnuts (if using).
Pour the batter into the prepared pan and smooth the top.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack.
