It’s kind of hard to find, the boulangerie Au Panetier, but it’s well worth the search. Found near the Place des Victoires in the second arrondissement it has an unassuming exterior. It is famous for its pain au chocolat blanc and the rich financier. There’s also room to eat there if you would like a little coffee with your pastry. I especially liked the interior inspired by the Art Nouveau movement with the walls covered in wonderful tile and tiled scenes.
