Instructions

Prepare the sponge. Mix egg yolks with granulated and vanilla sugar until fluffy. Add oil, water, and mix well. Then slowly add sifted flour, baking powder, cocoa, and finely grated orange zest. Beat egg whites until stiff peaks form, then fold them in gently. Pour the batter into a greased and floured baking sheet. Bake in a preheated oven at 180 degrees Celsius for about 35 minutes.

While the sponge is baking, prepare the filling. Boil half of the milk with granulated and vanilla sugar. In the other half of the milk, mix egg yolks and golden ears. Pour into the boiling milk and cook the pudding. Remove from heat and let it cool while stirring occasionally. When the pudding is lukewarm, slowly add butter and mix thoroughly.

Spread plum jam on the cooled sponge, then spread vanilla cream. Arrange either small diced oranges or mandarins from the drained compote on top.

Top with whipped cream made from cold milk and whipped cream powder. Chill the cake and decorate the top with oranges.
