Janda, you can also make cakes with WW flour and/or WW pastry flour (still WW, just made with a softer kind of wheat kernel). Both are readily available. You just have to experiment to see what works best for you. I would think that a carrot cake would be perfect with cream-cheese frosting and also be very good with WW flour (I've done it before and it's delicious!). Just find one that doesn't use any pineapple, and add a tiny bit more moisture (whatever kind they use) to deal with the extra dryness that comes with the WW flour.
For another cake recipe, check out my
Chocolate Cake with Peanut Butter Frosting recipes. The last poster (besides me) used the cream cheese frosting recipe on it.
