Dallas Desserts

My dad and I are big fans of desserts, and I'm curious to hear what other foodies have to say about the best desserts in Dallas (and the country for that matter). So far, my dad and I have reached the consensus that the best desserts are at the Palm. Their cheesecake is great, their chocolate cake is amazing, and their carrot cake is heaven. I consider their chocolate cake and carrot cake to be perfection. It does help that the desserts are huge (and $15 each). Besides that, if I am craving some dessert and don't want to gorge on Palm desserts, I usually go to Eatzi's, Dallas City Market, or sad as it is to say, Cheesecake Factory. I've tried places like the Grape (way too small and not tasty) as well as Stephen Pyle's Heaven and Hell cake... I guess you have to love peanut butter to appreciate it. I went to Hibiscus once and liked their chocolate cake as well as its size, but I think the Palm wins hands down. So where do you guys go? I am pretty conservative when it comes to desserts, but I'd still like to know your favorite dessert know matter how eccentric it is. Also, I think that Whole Foods "Death by Chocolate Brownie" is very good, and Del Frisco's has some good stuff too. Thanks.
