Vasina torta or Vasa's cake is an absolute classic of Serbian cuisine consisting of a walnut sponge base, a creamy filling made with walnuts, chocolate, and oranges, and two additional toppings – šaum (a mixture of egg whites, sugar, and a bit of water) and chocolate.
The cake dates back to 1908, when it was prepared as a gift from a mother-in-law to her son-in-law, Vasa Čokrljan from Paraćin, who took his wife to Vienna so she could give birth in better conditions than in Serbia. It should be noted that oranges were a real treasure in Serbia in 1908, which is one of the main reasons why this cake was so precious and valuable.
