Baker Charlie Dunmire, who recently graduated from Airstream trailer to a charming brick-and-mortar shop in Georgetown, fashions towering beauties like a ginger-molasses cake, its nine layers soaked in a syrup of stout and molasses. Or a s’mores-inspired confection layered with ganache and crowned with toasted whitecaps of marshmallow. Pints of Sweet Lo’s ice cream are available for purchase so you can double down on the sugar rush.
