Many kids of the '80s spent quality time churning out delicious (read: inedible) treats from an Easy-Bake Oven, but not everyone saw it as a future career. For Shareena Casterline, 30, her signature Easy-Bake "Shareena Cakes" were just the beginning of what later became New York City's Madison Street Bakehouse, an online bakery/one-woman-show run single-handedly by Casterline. \nWith a vision in mind for her bakery and whole lot of hard work, she made Madison Street a reality all on her own\u2014but not without sacrificing sleep, skincare, and her sanity at first. With that days start at 4 a.m. and include 13 or 14 hours of baking, working solo puts a lot of pressure on Casterline to be both business woman and baker for her loyal customer base. \nNow in her groove, Casterline has established that a balance of yoga and great skincare keep her feeling like her best self\u2014even on her longest days. Before bed, Casterline hits the mat and then starts her beauty routine, which includes L'Or\u00e9al Paris Revitalift Triple Power Intensive Skin Revitalizer Serum + Moisturizer and L'Or\u00e9al Paris RevitaLift Triple Power Intensive Overnight Face Mask.

"It makes me feel awesome," says Casterline, "and when I'm feeling awesome, I feel like I can do anything and take on everything."\nFollow Marie Claire on Facebook for the latest celeb news, beauty tips, fascinating reads, livestream video, and more.
