The sweetest mini celebration cake! layers of colorful, moist cake with vanilla flavour and a vibrant whipped cream frosting. Simple and suitable for small crowds, this little layer cake is delicious and fun for all ages!
I made this cake for my daughter maha’s 7th birthday. She wanted a rainbow theme so i incorporated rainbow and her favourite unicorn in one little cake. The cake looked super cool and colourful and the frosting is just awesome.
I coloured whipped cream with different food colours. Then i took a huge piping bag and added dollops of the cream into the bag. When i started to pipe around the cake, each layers got different colours and pattern. It created a lovely unicorn colour.
I have shared a different version of rainbow cake in this blog before. It has buttercream frosting in them.
I made this rainbow cake for my girl and she thought I was the coolest mom EVERRRRR!

How do you color cake batter?
Add 3 to 5 drops of food colors to the cake mix and stir it in. Check the coloring for the desired shade and add more food coloring, if needed. The cake will bake to a lighter color than the batter.
Which Flavour of cake is best?
Plain vanilla cake batter is best for rainbow cake. But you can make a plain cake batter. Divide it into several bowls, add each flavoured extract and food colours to each bowls and make different layers of flavour in a single cake.

Whipped cream frosting is best for rainbow cake, since the cake has several layers in them. Whipped cream makes the cake less sweet and little lighter. Buttercream can make the cake too sweet and rich.

RAINBOW CAKE SECRETS:
Essential tips about making this cake that will make YOUR life so much easier. Don’t skip this section!
- Use good quality gel food colours for vibrant colour.
- Use 8 inch cake pans. This batter is enough to make 6 to 7 layer cake.
- If you want the layers to be thin, add less batter in each cake pan and bake.
- Use leftover cake batter to make rainbow cupcakes.
- You can bake the cakes in advance, one to two days before. Wrap each layer in plastic wrap and store in fridge.
Important Things To Note Before You Start
1. Bring all your ingredients to room temperature or even a little warm (eggs, buttermilk, butter, etc) to ensure your batter does not break or curdle.
2. Use a scale to weigh your ingredients (including liquids) unless otherwise instructed (Tablespoons, teaspoons, pinch etc). Metric measurements are available in the recipe card. Scaled ingredients are much more accurate than using cups and help ensure the success of your recipe.
3. Measure out your ingredients ahead of time and have them ready before you start mixing to reduce the chances of accidentally leaving something out.
4. Chill your cakes before frosting and filling. You can cover a frosted and chilled cake in fondant if you wish.
5.All purpose flour is a plain flour(maida) with no rising agents.
