This melted rainbow cake featured on the Table Spoon blog offers bakers and cake decorators the chance to create a psychedelic ganache design.
To make this delicious vanilla rainbow cake, begin by baking a loaf of sprinkled vanilla box cake in a long, rectangular pan. Once the cake is baked you can slice the cake up into layers and fill the layers with vanilla frosting. Then cover the cake in a layer of vanilla icing and try and make it stick as smooth as possible to the cake sponge.
Freezing the cake helps with this too. Corn syrup, confectionery coating, heavy whipping cream and food coloring are used to create a heavy icing that will replicate the look of the melted crayons. Simply drop the chromatic icing down the side of the cake to create a dripping effect.
