The Best Cake in London Bakeries for Birthdays, Celebration, and Desserts | Eater London

"Outsider Tart is an American restaurant and bakery in Chiswick specialising in quintessential stateside cakes, bakes, pies and tarts owned by New York expats, David Lesniak and David Muniz. The New York crumb cake came about from missing the kind of “coffee cake” intrinsic to any American diner. The sponge is a soft yet sturdy vanilla sheet cake made with sour cream which helps achieve the textural bliss of a cake that has a tight crumb structure whilst remaining tender and moist. It is topped with a thick and crunchy layer of brown sugar cinnamon streusel, and finished with a vanilla milk glaze. Slabs of the two-toned coffee cake are a staple on the counter amongst a sea of regularly changing specials, and whole cakes can be ordered for delivery anywhere within the M25." - Emma Louise Pudge
