I've done well eating LC baked goods within some parameters. First, my whole day is LC, so no high carb dinners. Within my carb limit for the day, I can tolerate baked goods. Not everything I make is sweetened, but for those that are I tend to stick to Splenda (the measure-for-measure baking kind). It is higher in carbs than the packet Splenda so you have to make sure to account for that.
Some people find that certain sweeteners affect their insulin and therefore their results when trying to eat low carb. I do okay with Splenda, other people don't. There doesn't seem to be a lot of consistency with which sweeteners affect which people. But it sounds like you don't have a lot of metabolic issues (if you could lose weight eating on a moderate carb plan, which I guess is what LC breakfast and lunch, plus high carb dinner might work out to). I'm the same way, so you might tolerate most of them just fine.
I've gotten most of my LC baking recipes from
All Day I Dream About Food . I love her Cheesy Skillet Bread (I make this a lot--awesome substitute for corn bread), Raspberry Coconut Scones, Carrot Cake Pancakes and Blueberry Waffles for a start. I tried the Maple Scones once, but hated them--I think trying to substitute Splenda for the type of sweetener she uses didn't work for the icing. Plus the icing just made it way too sweet for me.

You also might want to dig through some of the archives on this site. Karen Barnaby used to be an active contributor here. I have her book and she included a recipe for "Colin's Omega Waffles" which I think came from another member here originally. They're a bit of pain to make, since you have to start them and then let them sit overnight. But I think they're worth it. They freeze well, so I make a big batch.
