Only one thing could possibly come close: the indulgent recipes in Candace Nelson’s The Sprinkles Baking Book ($17; amazon.com). The charming pair joined forces on Tuesday for the book’s pre-release party in Beverly Hills, where the actress made sure to get some face time with a gorgeous carnation-lined cake. Witherspoon arrived at the star-studded event in a navy pencil skirt with sparkling embellishments ($275; draperjames.com) and a matching collared top ($195; draperjames.com), both from the actress’s Southern-inspired clothing line, Draper James. The 40-year-old mother-of-three left her blonde locks down for the event, tousled waves dusting her shoulders. Complementing her relaxed ‘do, Witherspoon kept her makeup fun and minimal, adorning her famous smile with a bright raspberry lip and accessorizing with a simple pair of diamond stud earrings. The Oscar-winner added a couple inches to her 5-foot-1 frame with a pair of stiletto sandals that showed off her deep crimson pedicure.
