Just found this great link from the Smart Life blog: 155+ places to buy Chocolate, Candy and Cookies Online. Oh yeah.

Some of the favorites I can personally vouch for:

BurdickChocolate.com — Delivers chocolate assortments, chocolate dipped fruit, novelty chocolates, pastries, gift baskets, wedding favors, and more to 20+ countries worldwide, including the U.S. I’m not sure if they started in the Cambridge area, but there’s one right in Harvard Square that I visit every once in a while. The chocolate mice are my favorite, but there’s a whole bunch of good stuff. It is *very* rich, though, so I feel it’s best to keep them an occasional treat.

LakeChamplainChocolates.com — Offers fresh, all-natural chocolates in normal and gourmet styles from Vermont. These are one of my favorite chocolates; try the Sea Salt and Almond Milk Chocolate sometime. Seriously addictive.

DancingDeer.com — Offers a variety of baked goods including brownies, cakes, and cookies. Special occasion and bulk item orders are available. Another favorite of mine (particularly the Molasses Clove cookies, which are too good to be allowed in my house on a regular basis for waistline-maintenance reasons) - and they’re based right in Cambridge (the next town over from me)! 

GreystonBakery.com — Founded by a Zen Buddhist in 1982, this bakery offers brownies, specialty cakes, wedding cakes, and sundry desserts and is the exclusive producer of brownies for Ben & Jerry’s. The DoGoodie brownies are truly amazing - seriously. And, they’re a client of the zen kitchen, so I gotta give them some special love.

Go forth and treat yourself! Let me know what you try.
