Carrot Cake Victory - almost

I made a carrot cake on Sunday and it was delish. Why no photo? No camera! But I still need to tweak the recipe, so I'm making another one to enjoy with friends this weekend. The addition of orange zest is really what I've been looking for in a carrot cake all my life. And I don't use oil - butter, all the way baby! And after I shredded the carrots in the food processor I chopped them up really fine so there weren't these big long shreds o' carrot in there. What else? Buttermilk too!
