Low Fat Chocolate Cake

Ingredients:
3 1/3 cups all-purpose flour
1/2 cup unsweetened cocoa powder, sifted
1 1/2 teaspoons baking soda
1/2 teaspoon salt
1 1/2 cups granulated sugar
1/2 cup plain nonfat yogurt
2 egg whites
1 tablespoon vanilla extract
1 tablespoon vinegar
2 tablespoons confectioners sugar

Procedures:
Preheat the oven to 350 degrees F.  Spray a 13x9-inch baking pan with nonstick cooking spray.

In a medium bowl, combine the flour, cocoa, baking soda and salt.

In a large bowl, with an electric mixer at medium speed, beat the granulated sugar, yogurt, egg whites, vanilla and vinegar until fluffy, about 2 minutes.

With the mixer on low speed, gradually add the flour mixture; stir until just combined (do not over mix).  Add 2 cups of water and stir until just smooth.

Pour the batter into the pan.  Bake until a toothpick inserted in the center comes out clean.  About 40 minutes.

Cool completely in the pan on a rack.  Dust with the confectioners sugar and serve.
