Awesome - don't ya just like 'doctoring' a recipe.
I just made a cake that called for crushed pineapple but didn't have any. I substituted shredded zucchini (from last years crop) and added peanut butter chips. It really does take good. It calls for a butter, cream cheese and powdered sugar frosting...but I don't think it needs it for 'just around the house' eating. Now if I were taking it to a party, I would put on the frosting.
