It’s a sign the cupcake craze may be officially kaput, as The Cupcake Station in downtown Birmingham, 136 N. Old Woodward, has not only closed for what was initially a renovation, but has had a change of ownership and branding, as well. When the rebuild is complete, it will re-open as Bakehouse 46, where presumably cupcakes will still be available – along with an assortment of other baked goodies.
