Kouklet Bakehouse has a wide variety of Brazilian bolo de rolo, including a Philadelphia pretzel cake with salted caramel milk that nails the balance of salty and sweet. But it’s the plump, airy sonhos at this East Passyunk bakery that make us feel like we’re biting into a sugary pillow. The flavors rotate. So you might find peach, cherry and chocolate custard, or strawberry.
