Park Slope's newest bakery, Buttermilk Bakeshop, opened up at 10 a.m. on Saturday morning, and on both Saturday and Sunday they were entirely sold out by 4 p.m.
The owner, pastry chef Katie Rosenhouse, is a French Culinary Institute grad who was previously head pastry chef for the David Burke Restaurant Group, and there's clearly some real skill on display here. Everything from the baguettes to the croissants to the macarons, cookies, cupcakes, whoopie pies, linzer tortes, tarts, and cakes are baked on-premises throughout the day, many based on old family recipes, and they're all on display as well as several varieties of gelato (here's the menu).
Rosenhouse (above) can be spotted at all times at the workspace behind the counter, frosting cupcakes and replenishing the stock, which includes more than 30 individual items available at any time. Because it's such a small smace, the oven, workbench, mixer, and other equipment are at the center of the action and visible from the front window, giving it all a very transparent, hands-on vibe. The front counter area is also quite small, so don't be surprised if you see lines out the door. Everything I've tried from there has also been pretty damn tasty, another reason why there might be lines out the door.
The bakery is open Tuesday - Friday from 7:30-7:30, Saturday from 10-8, and Sunday from 10-6.
