This is cake about happiness, and equality. There is nothing sad about rainbows and all those beautiful colors in harmony together. You also can throw off the consistency of the vanilla cake batter if you add too much liquid food coloring. Gel food coloring is incredibly concentrated, so it allows you to use less.

A couple drops will create beautiful, bright.All seven layers in this cake are dyed a different color to match a rainbow.
To fill between layers of a cake, you can use any kind of filling such as peanut butter, chocolate filling, simple sugar butter or any other flavour like hazelnut butter and all.

When you add food coloring in the cake batter we have wide range of options instead of using artificial colors. You can use beetroot for red color and carrot for orange color and like wise blueberry for blue color, it may be vary in taste but for that we can add any flavour that we like.
