Rainbow Cupcakes!

I just had my 3 consecutive days of examination and my hands itched to bake so much!
This is my 2nd trial with rainbow cakes/cupcakes.
I bought my WILTON gel colours when I went to JB so I baked some Rainbow Cupcakes with them today! This entire project took about an hour and yields 9 cupcakes.
Recipe adapted from Cupcake Creations.

Rainbow Cupcakes

175g self-raising flour, sifted
150g castor sugar (or super fine sugar)
150g butter, softened (I used salted)
1 tsp vanilla paste (Mine's from PH)
3 eggs
WILTON gel colours 
(I used violet, blue, green, yellow, orange and red)

200g icing sugar, sifted
2 tbsp hot water
Cupcake decorations: Chocolate chips, 100s and 1000s, sparkly sand
9 cupcake cups

The ingredients!

Self-raising flour sifted.

Add the sugar in.

The butter.

My butter wasn't softened as it was an impromptu baking session. 
So, I cubed the butter with the back of my butter knife to allow it to soften faster. 

3 eggs!

Whisk them first.

Add the butter, sugar and flour in.

Mix well using an electric whisk for 1/2 a minute. 
Add the vanilla paste.

Mix more for another 2 - 3 minutes till it's light and fluffy.

Separate the batter into 6 bowls.
Add 1/6 tsp of gel colouring into each bowl and mix well.

Heat up the oven to 200 degree Celsius.
Scoop about 1 tsp of purple batter into the cupcake cup.
Knock the cupcake cup with the batter against your palm to allow the batter to sink into a flat layer.
Bake the cupcake for 1 minute and remove from oven.
The purple layer should be slightly cooked. 

Add a teaspoon of blue batter into the middle of the cup and pop it back into the oven for another minute.
Remove from oven and repeat steps for the green, yellow, orange and red batter.
Your cup should be 3/4 filled when it's filled with 6 colours.

Lower the oven's temperature to 180 degree Celsius and bake for another 20 minutes or till a toothpick comes out clean when poked into the middle of the cupcake.

The fresh cupcakes!
Set cupcakes in front of fan to cool.

My frosting was just a simple partial glaze to allow my cupcake decorations to stick.
Sieve the icing sugar and add 2 tbsp of hot water to it. Mix well.
If mixture is too thick, add a lil' more hot water.
If mixture is too thin, add a lil' more icing sugar.
Use the glaze as 'glue' to stick the decorations on it!

The final product! LOVE how pretty the colours are!

The cupcakes were moist and sweet. However, my mum didn't wanna try it cos it was too colourful and didn't seem appetising to her! The fav boy thought it was okay.. Maybe next time round, I'll try 2 tsp of vanilla bean paste to make it tastier! (:

But I really love the colours, it's like my HAPPY PILL! (:

I'd love to see the bakes or stuff you've cooked using the blog's recipe! Do share photos of stuff you've baked or cooked using the blog's recipe with me either via FB message to OR OR via email at! I look forward to hearing from you! (: 


  1. which part in JB able to find WILTON color? and is jb cheaper?

    1. Hello!

      Most newer generation baking shops in JB will have it.. But it's not really cheaper as compared to Singapore.. (:

  2. hi, i tried baking it about 15minutes but the inside of the cake is still not cooked. i baked for another round it seems to be burnt. and if i left it cool one side, it turns hard on the outer. any suggestion? tyvm! (:

    1. Hello,

      Recipe calls for the cupcakes to be baked for 20+ minutes. 15 minutes is way too little. And what do you mean by bake another round? Another 15 minutes?

  3. But it turns to be burnt and harden. Isit i put any thing too less tt causes it?

    1. Your baking timing is all wrong.. that's why the bake failed.

      Please follow the recipe properly. Bake it for 20+ minutes as indicated in the recipe and if it's not cooked, DO NOT BAKE FOR ANOTHER ROUND but monitor and bake it for several more minutes till a toothpick comes out clean when poked into the middle of the cupcakes.

  4. Hi Cynthia,

    I am curious. Do we really have to bake the colour one by one for 1 min? Can I simply put in all the colours, layer by layer (without mixing) and bake at one go for 20+ mins? Sorry if this question sounds stupid as I am a beginner.

    Thank you.

    1. I did that so that each layer 'sets' a little.. else the design might be rather different and possible mixed up.. then again, rainbow cupcakes baked all at once's pattern is highly dependent on the heat of the oven so even if you use the recipe, you may not get the U shaped design I got (:

  5. Hi Cynthia,

    Where do you buy your cupcake liners (solid ones)?

    1. Hello!

      They can be purchased from baking shops like Phoon Huat or Sun Lik.

  6. Hi Cynthia,

    Can I replace the vanilla paste with vanilla essence instead?


    1. Hello,

      yes you may do so but it won't taste as great (:

  7. hi i wld like to know which brand of gel coloring did u use and whr to get them


    1. Hello!

      I used wilton gel food colouring. You can get them from most baking stores.
