Ingredients

•    1/4 cup white flour
•    1/2 cup plus 2 tablespoons whole-wheat  flour
•    1/2 cup granulated sugar
•    1/3 cup unsweetened cocoa powder
•    1 teaspoon baking powder
•    1 teaspoon baking soda
•    1/4 teaspoon salt
•    1/2 cup nonfat buttermilk or ½ cup milk with 1 ½ t lemon juice
•    1/2 cup packed light brown sugar
•    1 large egg, lightly beaten
•    2 tablespoons applesauce
•    1 teaspoon vanilla extract
•    1/2 cup hot strong black coffee
•    Confectioners’ sugar, for dusting

Preparation

1.    Preheat oven to 350°F. Coat a 9-inch round cake pan with cooking spray. Line the pan with a circle of wax paper.

2.    Whisk flour, granulated sugar, cocoa, baking powder, baking soda and salt in a large bowl. Add buttermilk, brown sugar, egg, oil and vanilla. Beat with an electric mixer on medium speed for 2 minutes. Add hot coffee and beat to blend. (The batter will be quite thin.) Pour the batter into the prepared pan.

3.    Bake the cake until a skewer inserted in the center comes out clean, 30 to 35 minutes. Cool in the pan on a wire rack for 10 minutes; remove from the pan, peel off the wax paper and let cool completely. Dust the top with confectioners’ sugar before slicing.
