Rainbow Cake from Scratch.

I'm often unsure whether or not to be complimented when you serve something and people ask "where did you buy this from?" which has happened at least 5 times recently. Do you take it positively because they think what you've offered is so good they think it has to be done by a professional? Or do you take it as an insult because the person doesn't think you're capable of making something so nice?

Either way, I was asked this about this cake when I remade it for youth group, but most of them were just in awe of the colours.

I decided to redo this recipe only without the boxed cake and icing mixes, so here's a "from scratch" version for you - and it's just as fun the second time making this. I was also in shock at how many comments and links and emails I got about the Rainbow Cake I made for Taste and Create I just felt I needed to do it again.

Rainbow Cake from Scratch


175g butter or margarine
175g caster sugar
3 eggs
250g self raising flour
little milk (optional)

Butter Icing
75g butter or margarine
225 g icing sugar, sieved
2 tbsp milk
food colouring (optional)
sweets/hundreds and thousands to decorate (optional)

1. Preheat oven to 180˚C and grease two 17cm cake tins
2. Beat the butter and sugar together until light and creamy.
3. Mix in eggs one at a time, then fold in the flour. If the mixture seems dry add a little milk.
4. Split the batter into 6 and add the different food colourings.
5. Pour half of the first batter into each tin in the centre and tap it out to spread. Repeat with every other colour.
4. Bake for 25 minutes until form to touch and golden.

5. To prepare the icing, beat all the ingredients together until fluffy and light.
6. Leave the cake to cool on a wire rack, then ice and decorate.


  1. That really looks amazing. Great for a wee one's birthday cake. I must bear this in mind. Knowing me it would end up brown. Mixing colours always does that to me.

  2. what a nice and colourful cake. Ideal for spring :)

  3. Oh wow, how fun is that???

  4. What a fun cake that I'm sure gets lots of ooo's and aaahhh's. You definitely have more patience than I do.

  5. Going to go for it. Is the recipy for a double layer cake, or one layer?

  6. Thanks RG, hope you give it a go even if it does turn out brown!

    Thanks Nat

    Perfect for it Snooky Doodle

    Way much more fun than it looks Amanda

    It created a lot of excited teenagers giz lol

    Hi Mark - this recipe is for the double layer cake - hope it turns out well!

  7. I just love these cakes. Everytime I see one they amaze me. I love the pictures before the cake is cut.

  8. Made it for my tech class and they loved it. Used our own cake recipie and adapted it to your recipie. Really amazed at how simple it is to make and the massive impact it has when people cut a slice.
    I made two cakes for the class, one a chocolate, decorated with lots of chocolate stuff, and this one decorated with white iceing and love hearts (two of the class are getting married). The class went for the chocolate cake at first, but when they saw the inside of the rainbow cake, they were blown away. Thanks for the recipie,and i will use it for years to come.

  9. Thanks Ivy.

    Hey Mark! Great news! They really are so easy right? Glad you (and your class) loved it!

  10. This rainbow cake looks so beautiful with the colors, I'm sure it'll be a big hit with the kids! Nice rainbow colors! Although I'm to a big fan of rainbow cake, this sure looks yummy! I'm normally the one that will say no to rainbow cake. thank you for shearing your post.
