looking for a chocolate cake with vanilla frosting

does anyone have a low cal. recipe for a chocolate cake with vanilla frosting? 

    2 tablespoons cocoa
    1 1/2 cups flour
    1/2 teaspoon salt
    1 teaspoon baking soda
    1 cup sugar
    1 teaspoon vanilla
    1 teaspoon vinegar
    5 tablespoons cooking oil
    1 cup water

Mix all ingredients until 'just mixed'.  bake in oil-sprayed baking pan (9x9 or 8x8) @ 350* for 25-30 minutes.

It's 180 cals +/- for 1/12 of the cake.  Replacing the oil with apple sauce yeilds 130 cals for 1/12 of the cake!!

Can't really help you on the low cal vanilla frosting, but the chocolate cake is SUPREME.  Believe me! 

PS- don't let the vinegar turn you off... you can't taste it and it helps the cake to rise (no eggs) - go WW2!

you can make vanilla cream cheese frosting with low fat cream cheese and confectioner's sugar and vanilla extract.  Whip the softened cream cheese and beat in a cup or two of powdered sugar and a teaspoon of vanilla extract.  It won't firm up on the cake as much as it would if you made it with added butter, but gooey is good, right?
