One of the best baking blogs (in my opinion) is the King Arthur Flour one:
King Arthur Flour
Everything I've made from there has been excellent.
My other go-to cooking blogs (which include a subset of dessert recipes) are:
Simply Recipes Food and Cooking Blog
and
smitten kitchen
I have a host of dessert/cookie recipes that I often turn to. I can post them if required, and they are (in no particular order): oatmeal raisin cookies, chocolate chip cookies, brownies, blondies, chocolate cappucino cheesecake, bread pudding, mint chocolate brownies, fruit pies (apple being my fave), etc.
Best of luck!
