On April 13, 2005, the couple opened Sprinkles Cupcakes, the world's first cupcake bakery, in a 600-square-foot (56 m2)-shop in Beverly Hills, California. Though the bakery business was in a four-year no carb slump, they sold 2,000 cupcakes the first week. Candace is described as having a "sophisticated" take on the classic cupcake, using finest quality ingredients like sweet cream butter, pure Nielsen-Massey Madagascar Bourbon vanilla and Callebaut chocolate. She also creates offbeat offerings like vegan and gluten-free cupcakes and even dog-food cupcakes. The sleek, minimalistic store was designed by an architect from Vienna and the logo and packaging were recreated by a former Martha Stewart employee.
Sprinkles now has 10 locations throughout the United States, with plans to open in 15 more cities including London and Tokyo. The Nelsons also started a traveling "Sprinklesmobile", a Mercedes Sprinter van designed by Sprinkles architect Andrea Lenardin. In 2007 Candace also developed a line of cupcake mixes which are sold exclusively through her store and Williams-Sonoma stores in the United States and Canada. Sprinkles fans include Oprah Winfrey, Blake Lively, Katie Holmes, Ryan Seacrest, Tom Cruise, Barbra Streisand, and Serena Williams.
