Every other block in Stockholm seems to have a bakery or a coffee shop that also sells pastries. Swedes seem to love their pastries almost as much as the French.
Since it's almost impossible to avoid the bakeries in Stockholm, I simply gave in and sampled sweets all over the city. Some were better than others.
The best sweets I sampled were at a small bakery I wandered past near Östermalm called Fabrique. The look of the shop from the outside made me confident it was worth stopping, and I knew I was right immediately from the smell when I entered the shop.
The kardemummabullar (cardamom bun) was dense like an American cinnamon roll or sticky bun, but not hard or overly bready like some of the other buns I'd tried. The chocolate truffle was sweet and somehow light, and the shortbread cookie with dark chocolate and dried apricots rolled in pearl sugar was my favorite.
I don't know if it's really the best bakery in Stockholm, but it's the best I found! Fabrique has locations across the city. I visited the one near Östermalm at Nybrogatan 6. If you have to walk a ways to get to one, that's probably even better (definitely safer!) than having such great pastries right around the corner!
