I actually found carrot bread mix for this recipe (only available during the holidays, apparently). Added extra 1/2 tsp. nutmeg, 2 HEAPING teaspoons of cinnamon, and maybe a smidge extra vanilla. I would highly recommend adding some orange peel to the cream cheese mixture, maybe a teaspoon or so. I think it really enhanced the flavor.
These were very tasty. Got rave reviews at the potluck.
