½ cup granulated sugar
½ cup (1 stick) unsalted butter, room temperature
2 large eggs
4 ripe bananas
1 tablespoon milk
1 teaspoon ground cinnamon
1 cup all-purpose flour
1 cup whole wheat flour
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon salt
½ cup golden raisins
½ cup chopped walnuts
Preheat the oven to 325 degrees F. Butter a 9 x 5 x 3 inch loaf pan.
Cream the sugar and butter in a large mixing bowl until light and fluffy. Add the eggs one at a time, beating well after each addition.
In a small bowl, mash the bananas with a fork. Mix in the milk and cinnamon. In another bowl, mix together both flours, baking powder, baking soda and salt.
Add the banana mixture to the creamed mixture and stir until combined. Add dry ingredients, mixing just until flour disappears. Add in raisins and walnuts and stir until combined.
Pour batter into prepared pan and bake 1 hour 10 minutes, until a toothpick inserted in the center comes out clean. Set aside to cool on a rack for 15 minutes. Remove bread from pan, invert onto rack and cool completely before slicing.
