Looking for bakeries
You need to get out more. The cupcakes at Bakeshop in Arlington are in a whole 'nother league - and they are excellent across the board so you don't have to pick and choose.
In general, almost every bakery in DC is disappointing, even the better ones. I wouldn't go out of my way. Bonaparte (on sale at the Dupont Circle Farmers Market on Sunday mornings) is the best. Their French pastries and croissants are unusually heavy, but they are damn good. Even then, I would get them only if convenient.
Re Bonaparte, only in DC would you see a long line to buy baked goods without a price list.
They were not amused when I told them even Tiffanys has a price tag on their jewelry, and I do not buy anything from someone so ashamed of their prices they do not display them.
And no doubt they are heavy - pure butter I was told by a nearby vegetable vendor.
I've eaten at and reviewed just about every bakery in the Georgetown area, and I'd have to give my nod to Patisserie Poupon, at least if you want French Style Goods. Everything from the bread to the decadent mini-cakes to the infinitely moist and perfectly sweetened croissants is top notch.
And if you do end up going there, be sure to check out the Almond Croissant. It has a tiny layer of custard on the inside to keep it moist and add just a bit of extra sweetness.
I can also recommend the specialty Royale cake--chocolate with some crispy hazelnut feuilletine on the bottom. It's kind of like eating a Kit Kat, if that's your thing.
As a side note, I saw Baked and Wired recommended by another member. It's not a bad bakery by any means, but if you do go there, make sure you have a sweet tooth, because everything is outrageously sweet, especially the cupcakes.
And finally, if you're looking for cupcakes, you can't do better than Georgetown Cupcake, which is unfortunately the most overcrowded and most hyped bakery in the area, i.e. 30 minute waits!
Hope some of that helps.

I am a huge bakery fanatic but must say there's not too much going on in DC proper.
Baked and Wired is a fun bakery/cafe in Georgetown. No bread, but a huge variety of cupcakes, cookies, brownies, bars. I had a tremendous smores bar there last week with consisted of a graham cracker crust, marshmallow, caramel, and chocolate. Yum.
I also went to Yas Bakery recently in Rockville, MD. Persian baked goods, mostly cookies. They didn't look like much, but the flavor really knocked my socks off. They were absolutely scrumptious little spice-inflected (mostly cardomon) bundles.
