This is how you can create the perfect rainbow cake

The secret of this cake is the individually colored sponge cake bases, which together create a beautiful rainbow. You can use food coloring in gel or powder form for the colors - they ensure particularly bright results. A creamy vanilla buttercream is placed between the layers, which is not too sweet and goes wonderfully with the fluffy cake.

Decoration tips for little birthday fans

There are no limits to your imagination when it comes to decoration. Sprinkled decorations, sugar pearls or chocolate lenses make the cake even more colorful. If you like, you can also make small rainbows out of fondant or make figures out of marzipan. Small bunting or colorful candles, which guarantee the wow effect, are particularly popular.

Serving and storage tips

The cake tastes best fresh, but it also stays wonderfully juicy in the fridge for 2-3 days. Let it stand at room temperature for about 30 minutes before cutting so that the buttercream stays nice and creamy. It's best to cut the cake with a large, sharp knife - this is the best way to show off the rainbow colors!
