Eggless Rainbow Cake

When I first saw the Rainbow Doodle cake on Sweetapolita’s  blog, I was awestruck. I kept staring at the photos of the cake and wondered if I could ever do something remotely resembling that. Then I proceeded to Whisk Kid’s blog where Sweetapolita saw the cake and her daughter fell in love with it. One fine day, my Sister-in-Law suggested that I bake  her daughter’s birthday cake. As if I was just waiting to be asked , I agreed to the suggestion immediately. And what a perfect occasion to try the Rainbow Cake. I was apprehensive initially but then decided to go ahead.


UPDATE : For the basic sponge cake(eggless) – The recipe given below is for one layer only. Since I dont have a weighing scale  and I have a microwave cum convection oven , I baked  6 cakes using different colours for the rainbow cake.

Recipe Source : cookcurrynook

1/2 cup All purpose Flour

1/4 cup sugar

1/3 cup yoghurt

1/2 teaspoon baking powder

1/6 teaspoon baking soda

1/3 teaspoon vanilla essence

1/6 cup olive oil or any vegetable oil

8-10 drops of  food colouring – Red, Blue, Green, Yellow , Orange and for Purple you can mix Red & Blue together

For the buttercream frosting:

Recipe Source: Australian Women Weekly’s Baking Favourites

450 gms butter

5 cups of icing sugar

2- 3 teaspoons of vanilla essence

6 tablespoons of Milk


For the cake:

1. Preheat oven to 200 C. Grease a 6″ round baking pan

2. Mix sugar and yoghurt in a bowl until the sugar is completely dissolved. Add baking powder and baking soda. Mix it gently. Keep aside for 3 minutes

3. In the meantime, sift the flour thrice. Keep aside.

4. The yoghurt mixture would be airy and full of bubbles by now. Add the oil and vanilla essence to the mixture and mix gently.

5. Add the flour and gently fold it into the yoghurt mixture.

6. Add the food colour.

6. Pour the mixture into the greased pan and bake for 10 mts at 200C . Once reduce reduce the temperature to 180 C  and bake further for 10 more minutes. By this time your kitchen will be filled with the vanilla aroma wafting from the oven.

7. Once done , cool for 15 mts and invert it onto a wire rack for further cooling.

For the frosting:

(Will be ideal if using a electric mixer, since I dont have one, I did the whisking process by hand)

1. Whisk the butter so vanilla essence so that the butter becomes as white as possible. You will get a creamy colour here since you have also added vanilla essence.

2. Add the  sugar milk in three batches.

For assembling the cake:

1. On a cake board, spread a little of the frosting before placing a layer of the cake so that it doesnt move

2. Start with the purple coloured and alternate with the frosting and the coloured cakes  in the order as they appear in the rainbow.

3. Finally do a crumb coating of the cake and place it in the refrigerator for a couple of hours and finish with a final coat of frosting.

This cake was well received in the birthday party and the birthday loved the colourful surprise once the cake was cut.

  1. Thanks for the attempt of instructions on a rainbow egg-less-cake. The dough wasn’t even ready. After several attempts I have almost died of giving up. I wouldn’t recommend this website. Even to someone I highly dislike. I had a- many pain, stress and dislike to the instructions. It’s great knowing you succeeded though in troubling us . But would have preferred more instructions perhaps? Next time you could have been paid more attention to detail, and been more precise or even close . These instructions were PATHETIC . It was for my friend’s birthday and she didn’t have a proper cake. It didn’t even be sufficient for a mini cupcake, that, was how bad it was or edible. I’ll NEVER look back to this site.

    • First of all a heartfelt aplgogy for the stress and the pain caused due to the error in the instruction provided. The ingredients show the requirement for one layer of cake only. The rainbow cake needs 6 layers and this will have to be repeated as such using different colours. I have updated the post with the clarification. On an aside note, I would have wished you had written for clarification seeing that the batter was not enough for 6 mini cupcakes let alone 6 layers. Probably you could have avoided the stress. Just a thought though

  2. Hello
    Thank you for the effort for letting every one know this lovely recipe, i baked this for my husband, its turned out lovely. I think the brand i ve used for color has let me down its not as vibrant as yours. A general note when a recipe is posted I think its definitely a tried and tested recipe.. if it comes out well or not it depends on each individuals grasping power.. if it doesnt turn out well there must be some wrong in the technique they have used I dont think its fair to jus show anger on the blogger who has taken the time and effort to let others know how to do it..such act is very juvenile..
    Really Gayathri kudos to your effort… thank u so much ..
