Low-fat Key Lime Lemon Cake!

I wanted a sweet treat without a lot of fat and calories.  After rummaging through my kitchen I found a lemon cake mix and key lime pie yogurt.  I decided to combine the two and a yummy super moist cake was born.  Better yet one slice of cake is only 37 calories!

Ingredients:

1 Lemon cake mix

1 cup of Key Lime Pie yogurt

3 egg whites

1 1/3 cups of water

¼ can of vanilla frosting

serving size:  16

Preheat oven to 350 degrees.

Combine all the ingredients and mix for three minutes. Pour into a greased and floured bunt pan.  Cook for 40 to 45 minutes until a knife in the cake comes up clean.  Let cake cool for 10 minutes.  

Turn out onto a rack and while cake is still warm frost the cake.  It will melt and as it cools will harden on the cake.
