Despite being more a restaurant than a cake shop if you are looking for homemade, home baked and special, try Tierra Kitchen in Lyme Regis.
Their orange and pistachio cake with orange drizzle is outstanding
Alternatively if it is on the days menu try a slice of apple frangipane tart
The outside terrace overlooking a stream is perfect for tea and cake on a sunny afternoon. Found in the cultural quarter of Lyme Regis, Tierra Kitchen has a relaxed, down to earth and welcoming atmosphere. That is besides some of the best cakes, puddings and bakes to be found on the South Coast.
