She was born and grew up in Trottingham with her younger sister Victoria Sponge, her mother Lemon Drizzle, her Aunt Raspberry Drizzle, her cousins Red, Heather and Caramel, her grandmother Cotton Bud and sometimes her father Felix Carter. Her father's constant travels affected the family dynamic, especially with Victoria who began to feel Battenberg was the favourite and excelled further than her in every field. This led to tension between the two sisters as they grew older. After Cotton passed away and Raspberry fled to Cloudsdale, Battenberg and her family moved to Felix's hometown of Manehattan, where he and Lemon had lived many years prior to the birth of their daughters.
When she turned eighteen Battenberg began trying to make a living for herself and opened her first bakery in the city, Battenberg's Bakery. The bakery became very popular and various members of her family became involved, with her mother becoming the manager and her sister working alongside her in the kitchen. Her cousin Red Velvet occasionally produced grand multi-tiered cakes for the shop and Raspberry and her husband Citrus Orange provided the establishment with all kinds of wonderful jams to put in the cakes.
Because of the success of the bakery Battenberg began looking to expand and toured Equestria with her father, giving out her cakes and recording the responses. She found the most responsive location was Fillydelphia and set about trying to open her second bakery. During her time here she met the energetic pegasus Cupcake Sprinkles and her mother Strawberry Sprinkles. The two became close friends, bonding over their baking abilities and after Sprinkles told Battenberg about her wish to become a professional baker she agreed to take her on as an apprentice in the new Fillydelphia bakery. After a year's training Sprinkles in the Manehatten store and with arrangements complete Battenberg's Bakery became Battenberg's Bakeries and her Fillydelphia division opened with Sprinkles running the shop floor and kitchen and Strawberry becoming a co-manager of the business alongside Lemon. Sprinkles worked very hard and ran the shop so well that she was quickly upgraded from apprentice to Vice President of the company.
She has plans to open shops in Trottingham and Canterlot in the future.
