She's now set to open her 30th store by Valentine's Day â€” the company's busiest day.
And she's got more than just cupcakes in the oven. Butler, 40, is expecting her first child in May.
Butler was born in Lawton but spent her childhood on a farm in California. As a teen, she started a cleaning company, then moved to Nashville to pursue a country music career.
After years of singing in clubs until the wee hours of the morning, Butler hung up her singing hat but continued her cleaning business.
She decided to open the first cupcake shop in Nashville after her brother stood in line for two hours for a cupcake in New York and declared they weren't as good as Butler's.
Many of the cupcake recipes at Gigi's cupcakes are culled from family favorites made by her, her great-aunt or mother.
â€œWhen you take a bite of my cupcakes, you feel home again,â€ Butler said. â€œWe've lost the art of home cooking, but people still crave it.â€
