Easy cake with pastry crème Cremio

Beat the eggs and sugar with a mixer until the sugar is completely melted. Gradually add the Cremio pastry crème and oil, stirring with a wire by hand.  
Mix the flour with baking powder and vanilla. Add the dry mixture to the liquid mixture in small portions as stirring. Pour 2/3 of the mixture into a cake tin, and add the cocoa to the rest and mix. Pour the cocoa mixture into the pan and swirl it into the other mixture using a wooden utensil or a skewer to create random patterns. Bake in a preheated oven at 180°C for 35-40 minutes.
