Monkey Bars

1/2 cup raisins
1 1/2 Tbsp dark rum or apple juice
1 cup all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
3/4 cup packed brown sugar
1/4 cup butter, softened
1/2 cup mashed ripe bananas
3 tablespoons low-fat buttermilk
1 teaspoon vanilla extract
2 large egg whites
1/3 cup chopped walnuts
Cooking spray
1 tablespoons powdered sugar

Preheat oven to 350 degrees.

Combine the raisins and rum in a microwave-safe bowl. Microwave at high for 1 minute, and set aside. Lightly spoon flour into a dry measuring cup, level with a knife. Combine flour and the next 3 ingredients (flour through salt) in a bowl, stirring well with a whisk. Set aside.

Combine brown sugar and butter in a large bowl, and beat with a mixer at medium speed until well blended. Add banana and next 3 ingredients (banana through egg whites), beating well. Add the flour mixture, beating just until combined. Stir in raising mixture and walnuts.

Spread the batter into an 8-inch square baking pan coated with cooking spray. Bake at 350 degrees for 30 minutes or until golden. Cool the bars completely on a wire rack. After bars have cooled, sprinkle with powdered sugar.
