This is my doctored-up version of my Grandma Joyce's incredible carrot cake, and it is delicious! I've been low-sugar/sugar-free for several months now and really wanted this cake, so I reduced the oil, substituted Splenda for sugar, and used whole wheat flour. The icing option is high-fat but really tastes great, even with Splenda in it (and I haaate Splenda's aftertaste!). I don't recommend making substitutions for this recipe, as the nuts and pineapple are crucial for the flavor and texture of this cake. Enjoy!
