Sachertorte is a famous Viennese chocolate cake that was invented in 1832 by Franz Sacher. It consists of a dense chocolate cake with a layer of apricot jam in the middle, coated with a smooth chocolate glaze. The cake is rich and moist, with a perfect balance of sweetness and tanginess from the apricot jam. It is often served with a dollop of whipped cream. Sachertorte is a beloved dessert in Vienna and can be found in many cafes and pastry shops throughout the city.
