A birthday cake should not only look good, but also taste wonderful - and ideally everyone should like it! The vanilla buttercream birthday cake is a real classic that sweetens every celebration with its velvety aroma and wonderful creaminess.
Whether for children's birthdays or festive gatherings: with fluffy vanilla sponge cake base and a delicate, not too sweet buttercream, this cake will quickly become the centerpiece of your birthday table. And the best thing: you can decorate them however you like!
The perfect sponge cake base – this is how you can achieve it
The sponge cake base forms the heart of your vanilla buttercream cake. In order for it to be particularly airy and fluffy, it is essential to carefully crack the eggs. To do this, separate the eggs and beat the egg whites with a pinch of salt until stiff. The egg yolks are mixed with sugar and vanilla until creamy. Then carefully fold in the dry ingredients so that the air remains in the dough. Bake the base at 180 °C top/bottom heat until golden yellow - this will give you the perfect base for your cake.
The buttercream is the highlight of this birthday cake - velvety, aromatic and not too heavy. What is important here is the room temperature of the butter and pudding so that the cream does not separate when whipped. Real vanilla gives the cream a particularly delicate aroma and you can vary the sweetness according to your taste. The buttercream is also wonderful for spreading and decorating the cake!
This is how you layer and decorate the cake
Carefully cut the cooled sponge cake base into three even slices. Spread a generous layer of vanilla buttercream between each layer and smooth it all over the cake. For that birthday feeling, you can use colorful sugar sprinkles, fresh berries or small sugar decorations – whatever suits your taste!
Serving tip & storage
The cake tastes particularly good if it is allowed to sit in the fridge overnight, then the base and cream combine perfectly. Take it out about 30 minutes before serving so that the buttercream becomes nice and smooth. Leftovers will stay fresh in the fridge for up to three days – if there are any left at all!
