The recipe is designed for a deep baking sheet using a 0.2 liter cup.
Mix and whisk the oil, sugar and vanilla sugar. Then slowly mix in the flour and baking powder. When the mixture becomes crumbly, add the Fanta until a slow-flowing batter is formed.
Preheat the oven to 190 ° C top / bottom heat.
Line a deep baking sheet with paper and pour the batter into it. Bake the cake for about 20 minutes. When the surface is golden brown, let the cake cool a little.
Mix the icing sugar, lemon juice and Fanta into a frosting and spread it on the cake. If desired, decorate the cake with Smarties or sugar script (numbers, names, frames, etc.).
