Rainbow Cake | Rainbow Unicorn Cake
This rainbow cake just makes me feel so happy. I absolutely LOVED slicing into it to see all those gorgeous colorful layers! The best part is, this rainbow cake isn’t just for looks, it tastes absolutely amazing. You won’t have a crumb leftover.
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 make a rainbow cake?
Rainbow cakes are so easy to make. It can be baked in 6 easy steps.
- Make a vanilla cake batter.
- Divide into several bowls
- Add food colours.
- Pour into cake pan
Frequently asked questions
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.
Which Frosting is best for Rainbow 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.
Can we bake Rainbow Cakes in advance?
You can bake the cakes two to three days in advance. Wrap each cake in plastic wrap and store in fridge.
How long can we store this Rainbow Cake? Rainbow Cake Shelf Life? Fresh Cream Cakes Shelf Life?
Fresh cream cakes can be stored in an air tight container in fridge for 4 to 5 days.
HOW MANY PEOPLE DOES THIS RAINBOW CAKE SERVE?
Of course, it depends how big their cake bellies are (mine can fit in A LOT!) but this Rainbow Cake will serve 8 to 10 people comfortably.
If you want each layers to have different flavours. Here are some ideas.
Colours and Flavours which can be used in Rainbow Cake.
- Pink - Rose Extract
- Red - Strawberry Extract
- Blue - Peppermint Extract
- Green - Pistachios Extract
- Purple - Grapes Extract
- Yellow - Pineapple Extract
- Orange - Orange Extract
"Even though this idea is so much fun. I don't recommend it. Because the cake may get over powering with all those flavours in them. But it is definitely a WILD IDEA."
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.
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.

Rainbow Cake | Rainbow Unicorn Cake
- All Purpose Flour / Maida – 3 cups / 360 grams
- Sugar - 3 cups / 600 grams Powdered I used granulated sugar which i powdered
- Eggs - 4
- Oil - 1 cup / 240 ml I used refined oil
- Milk - 1 cup / 240 ml
- Vanilla Essence - 1 tblspn
- Baking Powder - 2 tsp
- Salt - ½ tsp
- Food Colours as needed
FOR WHIPPED CREAM
- Whipping Cream powder - 500 grams
- Ice Cold Water - 1 to 1.5 cups
- Food Colours as needed
FOR SUGAR SYRUP:
- Sugar - ¼ cup
- Water - ¼ cup
- Preheat oven to 180 degree C.
- Line three 8 inch round cake pan with parchment paper and set aside.
- Take flour, salt, baking powder in a bowl. Use a whisk to mix. Set aside.
- Take sugar and eggs in a bowl. Use a electric beater to whip it for 1 min or so till combined.
- Add vanilla and mix well.
- Add in oil and mix well.
- Add in half of the flour mix, half of the milk and mix.
- Add remaining flour and remaining milk and mix well.
- Now divide the batter between 7 bowls.
- Add food colour into each bowl and mix gently.
- Now pour the batter into the cake pan. I baked three cakes at a time.
- Place the cake pan in a preheated oven and bake the cake for 7 to 10 mins.
- Don't over bake the cakes. Bake until the cakes are just baked.
- Remove and cool for 5 mins. Un mould and peel off the parchment paper. Set aside in a cooling rack to cool.
- Now bake all the cakes like this and set aside to cool completely.
- Meanwhile whip the cream. Take cream powder and water in a large cold bowl. Whip it till stiff peaks form.
- Mix sugar and water and stir till sugar is melted.
- Now assemble the cakes. Take one layer of cake in a cake stand. Apply syrup.
- Spread cream on top. Stack each cake and repeat.
- Cover the entire cake with cream and put this in fridge for few hours till set.
- Divide the remaining cream between small bowls and mix food colours. Set aside.
- Take the cream in a piping bag, i used star tip.
- Now decorate the entire cake with the cream as you wish.
- Let the cake set for at least 5 to 6 hours.
- Slice and serve.
2)Never over bake the cakes. The cakes are thin so it requires very low time to bake.
3)Every oven varies. So the baking temperature varies accordingly.
4)I used whipping cream powder, you can use frozen non dairy whipping cream as well.
5)If you are using whipping cream, add some icing sugar and vanilla and whip till stiff.
6)Use best quality natural food colours.
7)Always keep the cream cold. so it is easy and pipeable.
8)If the cream gets liquid after adding food colour, whip it again for few minutes and then use.
9)Use gel food colour for best result.
10)You can decorate the cake as your wish.
11)Soak the cake in syrup to keep the cake moist and soft.

Superb.. I actually plan to do this for my son aarav's bday. (Jan 18).. I love your blog. picture presentation is great. Can u differentiate between baking soda and baking powder. ?

Hi Aarthi, loved this colourful cake...Can u pls tell me..How can I bake 2 cakes at a time?? Is it pssble to bake it in 28ltrs Lg microwave oven??
super delicious.. wow.. hats off for ur patience..
@shilpa goonu can bake 1 cake at a time.
I made the cake according to your recipe yesterday for my brothers 18th Birthday. I was very happy with how it turned out. The surprise element of when you cut into it is just awesome. I could not achieve the brown colour on mixing those four colours, and too much of icing overall made it too sweet for our taste, but it is the best looking cake I have made so far. Check it out:http://instagram.com/p/x2G-mnPiHy/
Thank u so much aarthi for d recipe...gonna try dis..I hope mine will turn out half as nice as yours....

@rohini murthycreaming butter and sugar till it is light and creamy will make this ssoft and fluffy

I just loved your cake Aarthi. I would like to prepare the same on my son's birthday, can you please tell how to make a eggless rainbow cake?
Aarthi this is the prettiest cake i have ever seen. Its not that I am trying to flatter you, but this is really a very pretty creation beacuse a lot of love and affection has got into it. In fact I love all the cakes that you have posted in your blog. I can see that you have used liquid food colour for the cake batter; have you used these for the buttercream also?
Congrats the cake looks yummy 🙂
Hi Aarthi, can you tell me the weight of the final cake?
it will be around 3 kgs
