More carrots and more cakes

I wonder why I keep making being requested to make carrot cakes. There are so many variations out there, that one could find a good one in a bakery, a "gourmet" supermarket...at this point I think I've made 2 layers, 3 layers, 4 layers and 6 layer cakes.
Is it the homemade pecan creme filling?  I could eat it out of the bowl with a spoon and it's good warmed up on ice cream :-)
Is it the cream cheese frosting?  Mine is butter, sugar, cream cheese with your choice of vanilla, cinnamon, orange, lemon, maple- maybe that's it!
In stores and bakeries, you don't get to ask if special requests can be considered.
