An elegant, no-bake dessert, this Strawberry Charlotte Cake is constructed by lining a springform pan with ladyfinger cookies to create the ‘walls’ of the cake. It is then filled with layers of more ladyfingers, fresh diced strawberries, and a light strawberry mousse. The mousse is made from pureed strawberries stabilized with gelatin and folded into a homemade sweetened whipped cream. The cake is chilled for several hours to set the mousse and soften the ladyfingers into a cake-like texture, then decorated with piped whipped cream and whole strawberries.
