Blueberry Bonanza

Tina requested the recipe for my blueberry white cake. Here it is:

Blueberry White Cake

1 box of white cake mix (I used Betty Crocker, but any will do)
3 egg whites
1 cup plain yogurt (I used Acme's generic plain yogurt, but any low-or-non-fat will do)
2 tbsp canola oil
1 cup water
1 cup blueberries

Mix and prepare the cake as indicated on the box, adding the yogurt after the oil. Add the blueberries last. Bake as indicated on box. I made a bundt cake, but I'll bet this would be great for a snack cake or taken to a Labor Day barbecue.
