Created a “few” years ago in honor of her brother Johnny’s 40th birthday, The Big “O” has been a fan favorite since The Dessert Gallery introduced it. What’s not to love?! Two creamy mousse layers – one white chocolate and one dark chocolate – are both filled with crushed Oreos™, and the whole creation is glazed with chocolate ganache.
